We had a ducted "multi-split" system retrofitted last year, upgraded from a ancient 80+ gas furnace. Not looking back - apart from being orders of magnitude more efficient, it's also a lot quieter and more comfortable as it keeps the temperature far more constant. Even in CA where such a system is an absolute no-brainer, I was shocked how ignorant or even hostile towards heat pumps some HVAC contractors are. One tech claimed that they are some newfangled technology that "always breaks", another gave us offers for gas and hybrid systems even though I was very clear about wanting to ditch natural gas. Imagine what we could achieve if just a fraction of the $30+ billion the US wastes annually to subsidize fossil fuels was spent on upgrading insulation and HVAC systems. Stay on your soap box, Alec!

Your comments on contractor price gouging are spot on. My municipality offered a $1,000 rebate for installing a hot water heat pump last year but you had to choose from their list of 16 installers. Each one of the first few installers quoted between $5,000 and $6500. By the time I contacted 6 of these contractors I realized this is just a scam to have the $1000 handed over to the installer plus they are gouging beyond that. I ended up calling a regular plumber who was not familiar with heat pumps. together we went through the install procedure and he installed it perfectly at $2,200. Most of that was for running the 22V electric since I previously had gas only in that corner. Even without the rebate it was still way cheaper than using those who manipulate government incentive programs. Plus I always wanted a couple of 110V electric outlets in that corner of the garage and he ran lines for those as well (included in the $2,200). So buyer beware in areas where you must use contractors from a specific list (please shop outside the list to get the real price)

Thanks to the resources you present here, I was able to: 1) compare my natural gas and electricity costs directly in kWh to find the breakeven CoP (3). 3) use historical weather data for my location to see that my winter temps are above 17 degrees Fahrenheit ~100% of the time. 2) use the NEEP list to find multiple heat pump models with CoP > 4 at 17 degrees Fahrenheit. Now I know that replacing my natural gas furnace with ductless mini-splits will decrease my heating costs. Thanks Technology Person!

Here in Norway heatpumps are mostly the norm if you're looking to upgrade your home in terms of heating. It gets cold here, and -12C in winter is common even along the coast, and inland it can get down to -30C, though it usually stops at -20C. Most homes now have heatpumps, it's rare to see one without it. We live in a newer home that already had a heatpump when we moved in, but it broke down after aproximately 20years of faithful service(and that had to do with bad maintenance), so just a couple months after we moved in it had to be replaced. The cost of ripping out the old one and installing a new one(both indoor and outdoor) came to 30 000 nok, which equals to approx. 3500 american dollars. And that was both the job and the price of the new system. So the price you guys have over there is outrageous, you shouldn't have to file for a loan to fix your heating, that's stupid. We've not had a single issue with heating this winter, though it crept down to -20C. I also have friends that live in houses as old as 300 years(yes, their house is older than the US), and with a heat pump installed, no insulation upgrade, and a woodstove, it keeps their house way above freezing without issue. They're planning on getting in some new insulation this summer, and are looking forward to their heat pump being more efficient because of it. Their heating and woodbills have majorly decreased after the heatpump got installed. So greetings from the arctic circle, heatpumps works here too.

Splits make a LOT of sense, compared to a ducted system. So much more power-efficient to just heat what areas you need, and not have all the losses in the ductwork. Also, having splits means that you can size them to heat/cool FAST, rather than having to leave everything running 24/7. I'm in Australia and there is no need to cool bedrooms *AT ALL* during the daytime. Using splits you can fire them up 10-15 minutes before bedtime, and the room is cool and ready to go. If a room isn't being used, just shut the door and leave the A/C off. PS: Americans: To prevent getting raped by installers, stop calling them "heat pumps". Just call them Air Conditioners, don't even tell the installers that they are Reverse Cycle.

@@JeffKubel - not with any form of energy efficiency. Zoning is literally just blocking off the vents to a certain area, let's say the bedrooms. You are still running a massive A/C system outside, you just aren't utilizing it's full capacity. So, let's say you have 5 bedrooms and only one of them is occupied, what do you do? Heat all the bedrooms, or not switch on that zone? And with zoning, each room doesn't get individual temperature control, eh ? Big central systems cannot cope with that - unless they use a very inefficient system called "reheat" where they heat/cool to suit the lowest temperature in all zones, then use resistive heating in a smaller zone's air-handler to make just that particular area warmer. Furthermore, ducted and zoned systems are usually undersized and designed to be run continuously. So if had the bedroom zone disabled and suddenly someone wanted to use a bedroom, you have to enable the A/C for that zone, and then wait quite a long time for it to bring the entire large zone to target temperature. Most people end up just leaving the whole house A/C enabled the whole time, which is extremely wasteful. One of the biggest advantages of split systems is to NOT have a huge A/C unit, but instead have a number of small units that you only enable if and when you need them. For example, right now there is only me here in the house. 2 stories, 4 bedrooms and only one person. A zoned central system cannot cope with just heating/cooling the room(s) that I am actually using. I hope that makes sense, it's hard to explain in a youtube comment. I have worked for a long time in the energy efficiency industry and these concepts are often difficult for people to grasp.

I have been disgusted by the experiences of friends family members in recent years as the large companies now dominating the local region are obviously engaged in serious price-gouging *and* seem to have a policy to refuse to repair existing units in order to encourage easy, high-profit replacements. And this was true even *before* the economic woes of the 2020's. I'm sure that it's even worse today. Get as many quotes as practical and look up equipment prices on your own to be as informed as possible.

That seems like a tremendously naive design that only made sense before we had cheap electronics. Especially if boilers large enough to heat the building can be built with variable output. Then you could maybe have per-apartment thermostats control valves that admit the hot water into a particular apartment's radiators, and linked up so that the boiler only puts as much energy into the water as is actually needed to serve demand. The upside is that if you have all the windows open maybe the airflow is better, but I can't help thinking there's better ways to do that (maybe not as retrofittable though; it's not like solenoid valves are big).

About a decade ago the government also subsidized insulation installation for 1.2 million homes for AU$1.5 billion (approx. one B-2 Spirit stealth bomber), the program has since saved >100 TWh of electricity, pushed back the growth trend of natural gas consumption by two years and saved an equivalent 27 million tonnes of CO2.

The problem here is he is simply too focused on his own area. In my area, steam heat is common as is the 75 plus year old rowhome. Some of the rowhomes are so old, they go back before the turn of the 20th century. Many of the homes in my area were serviced by central steam heat and that still exists in some parts of my city (Philadelphia). Retrofitting insulation is not particularly easy or even possible. Running duct work is not possible. Steam heat uses only 1 pipe (steam rises gets to the radiators, condenses and falls back down the same pipe it rose in) and so hot water heat is not possible. It would be MAJOR construction to tear out the plaster walls to get to the pipes. Outside of the city, nobody has natural gas, they have oil tanks. Oil fluctuates and heat pumps would probably be better than the oil. NOBODY is going to dump thousands of dollars in a completely new system for some abstraction like reduced co2

5:00 I'm reminded of the topic of incentive Nudges as policy - in England(? I could be forgetting details) they really wanted people to insulate their old homes. Tried all the things, carrot and stick. Very few takers. It wasn't until the policymakers examined the pain points of insulating an old house that they realized that it was all well and good to offer cheap/free insulation but most people were reluctant because they would have to clean out their attic full of storage. Instead of paying for insulation, they started offering an attic clean out service (plus insulation) and suddenly the adoption skyrocketed. If someone offered me 'nebulous future utility savings but I had to do physical work' I probably would pass...but if they offered to clean my house and give me nebulous savings...I'd be on board.

Thank you for this information. I live on Gabriola Island in BC Canada. Here we have a community program started by an enterprising small group of retired professionals and a willing HVAC professional. They researched heat pumps 10 years ago and decided on the high efficiency Fujitsu. They became a Fujitsu dealer and have been bringing the 12,000 BTU mini split into the community at wholesale. They arranged for a local installer and, once the physical installation is complete the HVAC guy comes by and commissions the unit. In our small community they have installed over 1000 units, even giving some away to needy recipients. BC Hydro has noticed the huge reduction in demand during the winter because most systems replace baseboard heaters, and hundreds of homes are more comfortable and more healthy during the winter (and air conditioned during the summer!). Community in action! It can be done!!

I love this channel so much. One of my all time favorites on youtube. You have an incredible ability to succinctly explain complex stuff. I just wanted to point out that Insulating without Air-sealing can be very problematic. Any time you insulate, you should also air-seal--and vice versa (especially in older homes!) to ensure that the thermal boundary and pressure boundaries are aligned. For example, if you insulated an attic and didn't air seal, now all of the sudden the attic is significantly colder than it was before, when it was heated by the warmth flowing up through the living space. If warm moist air from the inside of the house is still able to make it up through the attic, then you can get condensation on the underside of your roof and create mold and mildew problems or rot your roof off. I'm a Weatherization auditor and I would love to continue to see you explore topics related to weatherization. Maybe a blower door video?? I feel like that's totally up your alley. Thanks for all your amazing work, Alec!

Bradley, A blower door video would be great! Why not make one yourself? Try to write out a script, and then read it without saying Um every 30 seconds! It really helps to practice the script a couple of times before going "Live" on video tape. You have seen those video's where the commentator is saying um all the time, and you hate it - Right. At my house, the State of Oregon sent out a auditor who did a air duct leak test. They never closed off the air filter, or put anything in to stop air backflow through my 4 ton heat pump. They "Claimed" that there is air loss from the air ducts of 250 CFM or something. Then they removed every floor register, and put in duct sealant, and did the test again. Surprise, the ducts are now sealed with less than 50 CFM lost at this test. I never did tell them I know a thing or two about HVAC and air flow. What a rip off, but at least my air ducts have sealant in the area where they meet the floor, and actually are sealed better than before. To do a true test, I would seal each air outlet vent with a plastic shopping bag, then place the vent register back in place. Then with the air filter also in a trash bag, and put back into place, the only air duct open now could have about 1" of static pressure to see how many CFM of air is flowing into the air ducts, and thus out the door! I have seen diligent air loss tests, where the air door blows air into the building, and they used a chemical sprayer to shoot soapy water onto the exterior of the home, to look for leaks. Like around the electrical outlets, window frames, door frames, ect. They got lots of air bubbles. Even at 0.25" of water column pressure in the home. It made quite the display on that video! Soap bubbles everywhere!

That may have been the best impression of a condenser starting up that I've ever heard. You've got some good info here. We are currently building a new house in Niles, IL and I really geeked out on the HVAC system. 96% two stage gas furnace, 18seer two stage heat pump, zoned duct system, and in-floor hydronic to boot. Thermostats are programmed to use gas equipment at lower outdoor temps and the heat pump when it is more mild. With 6kw of solar on the roof and gas rates increasing lately, I may end up pushing that threshold temp lower as long as the HP efficiency remains decent.. I've done the entire installation myself (I'm a contractor) except for connecting the lineset and charging the system. I basically had to 'trick' my HVAC guy into thinking he was charging a standard a/c unit by not springing it on him that it was a heat pump until he arrived. Pretty sure he's still not happy about it (the charging process is exactly the same). Every HVAC contractor I have discussed the subject with around here have scoffed at the idea of a heat pump.

The house was built in the late 50's.

I'm replacing an oil furnace and this house will have AC for the first time in its 132 years of existence.

When I saw the numbers on these latest generation of units I was surprised and impressed. Unfortunately the particular unit I want for _my_ place has been on backorder for months or else I would have been able to heat with that this past winter, which would almost have paid for itself in one year just with the energy savings.

One of the things I've noticed in the builder/contractor scene being a GC in the southeast for over a decade is that there are a LOT of "old school" techs out there that are afraid to adopt new technology. They've been installing the same ac/heat pump units for decades and they know it down to the tee, brazing lines, climbing in sweltering attics and damp and cramped crawlspaces to install air handlers and evaporators is all part of "how it's done" in their minds. They know what it takes and can give a solid price number that they are comfortable with. I hate to use the "ok boomer" analogy with it, (I'm knocking on 40 atm), but their resistance to trying anything other than what they can do blindfolded makes them overcompensate in pricing for "that new-fangled stuff the kids are talking about". I see the same issue with metal frame homes vs traditional stick construction. Had 2 friends in nearby towns have nearly identical metal homes built right b4 covid. One hired the well known contractor that had built stick homes for 40 years, the other found a builder that was familiar with metal buildings. The cost difference due to change orders from the stick man having to order additional material (he framed everything 12" on center, thus wasting literal tons of material as he could at least gone 16" or up to 24".) But the point still stands, the stick builder built the metal building as if it were traditional lumber because he was unfamiliar with a different building practice and mindset in general. I was also told his labor cost was also about 20% over what he would have charged on a traditional stick building bc of the "added complexity". My century plus home has/had a traditional 3.5 ton outdoor heat pump/air handler combo on it. The previous owner added around 2000sqft to the house but didn't upgrade the unit to compensate (standard estimates call for a ~5ton unit for the total size now. Regardless, the unit finally gave up the ghost last winter as it would normally run full tilt with emergency heat just to try to keep up with the piss poor ductwork for the house (6 vents alone in the kitchen that was directly against the wall where the unit was installed.) dropped pressure to the point that the rooms at the far end of the house (3 rooms with 2 ducts each) each room only had 1 duct connected and even then, airflow was marginal at best. All that being said, I am looking to install 2 mini split systems next month. I have sized the outdoor heat pumps to be overkill for the initial install. They are capable of 4 heads each but I only intend to run 2 heads to start for the downstairs then will add additional heads upstairs later if need be. I had intended to do all the work myself from the get go, but called a few local hvac techs to get quotes for just install (I would provide parts) and all of them gave quotes that were around 2 times their quotes to replace the traditional unit and upgrade the ductwork compared to just installing parts that I was providing separately.

Well, am I glad I live in Australia. I paid about $600 for my Mitsubishi split A/C system, installed it myself, and it all runs on sunshine. Ok, the climate here is much like San Diego, but I originally came from Canada, so I know what it's like up there. But your presentation brought home the extent to which North Americans are chained to the existing methods of heating & cooling. It's going to take quite awhile for this to change. You are probably the most effective motivator there is at present. The people in the industry don't want to change; neither do the people who make the rules and regulations. But they have to. Especially if there's someone like you standing there beating a drum. You're not wrong about the noise issues. The outdoor unit for my bedroom A/C is less than a metre from my head when I'm in bed, with a very thin wall between. Yet I can barely hear it when it's running, even when it's going full tilt. Did I mention my hot water heat pump, that I made myself out of a dehumidifier? Ok, I had help from a friend in the refrigeration industry, but I gassed it myself with propane, and it works just fine., It needs to run for maybe an hour to make enough hot water for a shower. Rather than try to invent a complicated thermostat system, I just put a 2-hour clockwork timer in the power line to it, so I can run it whenever I need some hot water. In the summertime, I don't need the heat pump, there are 3 solar panels on the roof that are connected directly to the water heater element. The heat pump is needed in winter because there's not enough sunshine. Works for me.

My name is David and one year ago I moved into a home from ruffly the 1930's. One of the first upgrades we made to this h9use wich had no central heating and air was to centrally mount a heat pump system. I used your videos to do the installation with some help from the directions and other KZitemr's. Over the last 365 days or so this is what I have observed For the space I am using this single unit in (1500ish square feet) it works wonderfully for heating and cooling the home. With a few ceiling fans we are able to move the air across the house. We have found this to be a bit of a necessity as if we do not then we end up with one or two rooms climate controlled and the others closer to the exterior temperature. The insulation did not require any special tools however I did get pipe cutters so I could shorten the distance of coper pipe. I had a service tech check it after my installation and he said it was all good. The unit runs some days all day and night in the winter with no problem thus far. I am curious to see how it handles this summers heat. That is my report of the unit and of the product/idea. I am very please and after some rewiring we will be adding insulation and I'm excited to see the effect. New windows will be last as far as insulation goes (large older odd sizes)

The house is 132 years old and has exposed brick in a couple of rooms. In order to insulate it properly we'd probably have to renovate the entire thing. And the upfront cost is just... phew. Funny enough our neighbors got a heat pump last year, one of the Carrier mini splits, and all he had to say about it was "we overpaid". I'll have to really crunch the numbers and make sure, but dang, I'm disappointed.

It's shameful! We are so set up to have heat pumps, but domestic availability is generally quite crap and the HVAC trade really likes to gouge for mini-splits. There are some issues that will need to be solved on a case-by-case basis, for sure, but Asia has innovated some amazingly flexible equipment - if only Carrier, Lennox, York etc. would kick into gear and start copying their successes.

actually old houses are fine to use a heat pump UNLESS there has been zero upgrades done in the past 50 years but at that point you might want to invest in some double glazing first. please get this basic concept to get your mindset correct: insulation (or lack thereof) only tells you how much energy you need to heat your home, not how to get said heat into the home. your home does not care if the kW's come from a heat pump or a gas furnace, heat is heat. the only thing you want to focus on is keeping the water temperatures (if you use radiators) as low as possible. i have converted dozens of very old homes over the years. not once have i failed in making the home gas-free.

I'm working on convincing my parents to replace their decades-broken AC system and 60-year-old furnace with a heat pump, and this video going into specifics about brands that can be used to replace such an existing system is especially great for that! They've been getting hit *really* hard by their gas bills in recent years, which is the main reason I'm getting through to them about a heat pump being a good idea. Though I imagine that insulation is probably an equally, if not more important thing to do, in their 1960s-built California home. I *know* their windows are garbage, but they have over a dozen BIG ones, and several are these old-style "bulging window frames" where there's a huge empty frame with a shelf *outside* the walls, and *then* the window panes themselves in this elaborate metal edifice with several panes of glass per window. It'd be ridiculously expensive to replace all these windows... But they did just get their entire attic cleaned out, so adding new insulation up there might well be fairly easy. But they *also* need a new roof soon, onto which they intent to add solar panels. So these home improvement costs are getting astronomical... Oi.

Homeowner in NYC here 🙋♂️ After finding a gas leak in September 2022, I was told by my energy provider that I would have to bring my 100-year old gas pipes up to code before I could get my gas turned back on. Plus, the city would need to come out and inspect work. All in, I was looking at a $14,000 job plus 6 weeks or 6 months time-I could never get a straight answer. Decided to go all-electric given we were facing down cold weather soon. Got a few quotes from some HVAC people ranging from $15,000 to $80,000 for a 72,000 btu heat pump system to replace my 90,000 btu gas steam boiler in my 1,300 square foot single family house. What sucked for me was that the state incentives for converting to all electric heat had run out and federal incentives wouldn’t be available until early 2023. I went with the cheaper option and couldn’t be happier. The install isn’t beautiful, felt like a DIY job if I’m being honest, but the system works well. Before converting to all electric, I must have spoken with a dozen plumbers who all told me that the heat pumps wouldn’t keep up with winter cold and getting rid of gas would devalue my home. I think the HVAC installers all quote on the high end because they know one quarter to half of the cost is being covered by government incentives. NYC has passed legislation instituting a moratorium on new gas hookups in 2024 so I hope the HVAC industry gets their act together soon.

Alec, thank you for pointing out the price gouging. I was turned away from an HVAC company for a mini split because they claimed they no longer had a mini split person. As if it is really any different to install. 3 others quoted 10k per indoor unit, the equipment was about $4500 shipped to me and they wanted $30k to do it, nothing more than greed. I ended up going with a MrCool unit that requires no vacuuming of line sets and is an easy DIY. If a local company had quoted me 12k to install a 3-4 indoor multi-zone system they would have gotten a sale instead they all wanted more than double that and therefore I did it myself over a weekend. The industry needs serious changes or else they will lose to more DIY options.

The biggest issue for DIYers is that many HVAC companies will not service your system if it wasn't installed professionally. I am fairly confident if I ever have a failed part on my DIY installed unit, I'll struggle to find someone to fix it. But given the price difference of 30-40k for a 3 or 4 zone unit, I could easily buy 8 systems at the current price before my investment was a bad deal. I'll take those odds even if it is incredibly wasteful to essentially throw away a system if I can't fix it or get it fixed. The good news is they are relatively simple systems and parts replacement outside of the refrigeration loops is likely very doable. We'll see if I have any regrets in the future but so far I have none.

I recently replaced my heat pump in Central Florida. I was surprised by several companies that were trying to talk me out of it. I asked a lot of questions pretending I didn't know about heat pumps and got a mix of good and bad answers. Also I had a 3 ton unit and just over by a few square feet to move to a 3.5 ton unit. In the end I found someone with very little markup for a heat pump, took time to add freon in my old leaking system to help determine if the current system would cool well enough and give me options that made sense. Luckily for me my Honeywell smart thermostat showed over 150 hours of use for heating in the winter. I had 7 quotes with only 3 that seemed like they understood heat pumps and the reasons they were valuable. A couple companies said that they just were not needed because it didn't get that cold. It got down in the 30's last winter which would have been too cold in house for me. I used heat pumps in Missouri and Kansas and they worked great until it got below 25 degrees Fahrenheit for the older units. Makes sense in most of US.

Hydronics is very underrated. It allows to add a whole new level of flexibility. For example, you can use the hot water tank to shift the heating (or cooling) demand by preheating or precooling it in advance, when the electricity costs are lower. You also can use hydronics with head units that simply run hot/cold water through heat exchanger instead of refrigerant.

In our new farm house we added a layer of clay onto the brick walls. Then wood shaving insulation panels and another clay layer. Next the pex tubing and another thick layer of clay. The whole wall is open for steam release but with good insulation values and lots of thermal mass. Another benefit of this style are lower temps in the lines (better for heat pumps) and the moisture regulating properties of clay. We are going to install solar, a heat pump,plus a sensible heat store (insulated water tank). When the sun is shining we will preload the walls and tank in the daytime and use the heatpump less at night.

You're right about the price gouging going on. I live in the Seattle area and wanted to get a mini-split system installed last spring. The cheapest quote I could get for a 4-head 3 ton unit installed was 12K. The high end quote I got was 19K. I ended up going with the low bidder, but it turned out to be something of a mistake. The technicians really didn't know what they were doing and it took 4 follow-up visits and a different company with competent techs to figure out that they didn't tighten the flare connectors enough to stop them from leaking refrigerant. I blame part of the cost on inflation and demand, though. There are a lot of people retro-fitting similar systems for cooling around here as our summers are becoming increasingly hot and most of the existing houses weren't built with cooling systems. I'm still very happy I did it. The cooling made last summer's record high temperatures actually bearable, and our heating costs this winter have been significantly lower (we have a gas furnace).

I live in a pretty high price area too. I have the common central ducted system with a condenser outside and a furnace/evaporator coil inside. My system was over 20 years old and the outdoor AC unit was dying, it was either fix it or replace the system. Decided this was a good time to switch to heat pump as I didn't want to risk a broken AC during the sweltering summer here and heating oil prices are only getting worse, epically with the current supply chain issues. Last year my AC broke in the middle of summer and it took over a month and a half to get a replacement part and I didn't want to go through that again. For a 3.5 Ton SEER 16 HSPF 9 heat pump + new air handler I was quoted anywhere from $9.5K to $14K (depending somewhat on the brand: Bryant was cheapest, Carrier & Trane was middle of the road, and Lennox was sky high). This was for a normal "entry level" single stage heat pump, not a mini-split, not a multi-stage or variable speed, and not a cold climate heat pump. When I looked at systems that were cold climate adapted, basically could pull heat even at 0F with very little loss in efficiency, the prices where through the roof! We are talking $18K - $30K! I wish there was more incentive to bring this new tech down to the masses, I think it could help a lot of people but right now the tech seems to be limited to only the premium and luxury models. I got quotes from 4 different vendors so it wasn't an outlier.

Promising as these are, and as far as they've come, I feel like I'm stuck in the mid '80s, shopping for a computer, and looking at paying $4000 for an 8088 running DOS 3 from floppies at 4mHz. Retrofitting my house with a heat pump was quoted last year at over $30,000, and that's really hard to justify when the existing boiler and occasionally leaky radiators heat the house pretty well for around $1500 annually. If electricity were free, I'm still looking at a 20 year break even point, assuming I've even got that many years left. I'd be happier to rip out the whole rusty, noisy system and replace it with a minisplit but as you mention, there just aren't a lot of contractors out there willing to do this for a fair price. I'm confident I could do the work myself, but it's just not in my aging bones to take on that sort of a DIY project anymore. The only hope for our planet is that my computer analogy is correct and that the $4000 desktop system evolves rapidly to become the $300 laptops we have to day, faster, cheaper, better and longer lasting. But to deploy heat pumps where they could make the most difference, not only reducing emissions, but creating financial stability for millions of families, is going to take an effort comparable to rural electrification, and I do not believe the US has the political will to carry it out.

Purchase and installation was about $6,000 CAD in 2016, under $5,000 USD. We paid an electrician to come out ahead of time and prep a breaker circuit for the unit, which was coincidentally super cheap because for some reason this house had two oven circuits even though we only have one kitchen, so a great circuit was just sitting there empty, waiting to be used. It may be important to mention that 1) we bought through the installer, who runs a one-man show, and 2) the Newfoundland provincial government is really pushing for non-gas heat solutions.

We had a minisplit put in just over a year ago, and I am so glad that I paid the exorbitant prices from a local HVAC company instead of doing it myself. Every 2-3 months, it would lose the last of its refrigerant, and we would need to have it serviced. I got to know the technicians (pretty much all the ones this company had), since they were in our house so frequently. They were extremely knowledgeable and capable, and seemed to assure us each time that the problem was actually solved, but, as you can tell, it wasn't. Eventually the head was completely replaced, and that fixed the issue, but before they reached that point, there was at least 60+ hours of work spent trying to diagnose and fix our lines. Even though it was a bit more than a year (the term of our warranty), the installation company never charged us a dime, which is amazing since for every hour they spent installing this unit, they spent 10 hours on service calls, not to mention at least a thousand dollars on refrigerant (it was replaced probably 8 to 10 times in that year+). I think this is why quotes are so high.

I have to say that my experience lines up with your anecdotes. I live in NC USA so I need both heating and cooling, but more cooling. I added a Mitsubishi minisplit to my garage so I could work out in it during the summer comfortably (and I love it!). The first company I called that had serviced my home's barrel style heat pump didn't do minisplits at all for some reason. Later I had my A/C go out in August due to a cracked coil and the recommendation was to replace the condenser and coil given the age of the system. I wanted a variable speed system with high efficiency, but that would have been a 2 month wait and more than double the cost, even though the installation would have been essentially the exact same. I didn't want to go months without HVAC, so I got something very similar to what was originally installed, which is a 14 SEER unit. In the winter the aux heat comes on for a lot of the time and I end up further supplementing with my gas fireplace. I hate it. For a future video I think you should do something on HRV/ERV units that are installed in very airtight homes, like those following the passive house standard. It's a very interesting technology and I think we ought to be pushing codes much closer to passive house standards for both insulation and air tightness. They are dramatically more energy efficient, and have additional benefits including much better indoor air quality (and in NC we have horrible pollen in the spring) and are much, much quieter indoors. Homes like this can often get away with a much smaller HVAC system, and the "lego-like" split systems you talked about are great options there.

We replaced it under the California Energy Upgrade plan with a 3.5 ton split two state variable speed heat pump with electric auxiliary heat with two zones and it’s been really nice. The old unit was an American Trane. The new unit is a Bryant (Carrier). I asked for a 3.5 ton oven a 3 ton recommended because I didn’t understand why the previous was 5 ton. And the O terminal is the reversing valve pin for most thermostats but not Trane- I think it was C. Servicing my dying unit the HVAC contractor shorted the reversing valve and blew the fuse confusing it for common. I knew the difference because I downloaded the manual. Then when it frozen over, I diagnosed the defroster board was bad. They didn’t believe me and replaced it only to humor me and exclaimed it was bad when they saw scorch marks on the board replacing it- no they hadn’t check when I mentioned the symptoms matched- they just kept saying my filter’s probably dirty despite me having replaced it. I should not know more than the expert I hire to do the work. The contractor seemed familiar with ducts and coolant lines but seemed completely untrained on the electronics.

Part of the maintenance was smacking the Taco superheat pump so it would make hot water that keeps the heating load balanced, it’s impeller had seized from buildup since the relay was bad.

I installed a Blue Ridge 2 head mini split system into my small (576sqft) home, and it was easy. My friend had a vacuum pump, and we did it all in probably 2 days of work, most of which was drilling holes in the block walls. I think all in it was less than $2500, and seems to work great. Thanks for the recommendation of a heat pump! Otherwise i would've gone with window units and space heaters lol.

I would love to re-insulate my house, install new windows, and look into switching into a heat pump with gas for emergency heat, but we also need programs to assist folks who own older homes that contain asbestos. What would be a relatively simple (yet not inexpensive) reinsulation project turns very quickly into something completely uneconomical when the ridiculous cost of asbestos abatement is factored in. It almost turns it into one of those "It's cheaper to demolish" situations, but I can't justify the cost and disruption to my life in order to do this. So I'm stuck - I can't afford a better home because home costs have gone crazy, and I can't afford to resolve issues in my current one in order for my life to become "greener". Sigh.

It's surprising how many homes have some kind of complicating factor like this - and they're the ones that would benefit the most from upgrades! Although asbestos removal can be inexpensive. Recently had a contractor look at my asbestos drainpipes - and they said they'd have to remove them but they could double bag them leave them here and we (as residents, rather than a company) can get a local authority to take them for free. If they took it away (as a company) they'd need an asbestos license and to pay per kg. In my case - I want a heat pump but don't qualify for a grant because I don't have cavity wall insulation. I can't get cavity wall insulation because of concrete gutters - they're known to fail over time and leak onto the insulation, causing really bad damp problems - so no regulated installer will install it unless the gutter has a guaruntee'd lining. So in order to install a heat pump, I have to remove/reline my gutters 🤯🤯

@@naxxtor Certainly, sometimes asbestos removal can be fairly inexpensive, especially in the case of Vinyl Asbestos Tile, Pipe Insulation, Acoustical Ceiling Tiles, etc. In my case, there is use of Zonolite-Sawdust/Asbestos insulation in the walls and ceiling spaces. Tearing open all the walls - even the upper level floor (which used to be an attic) to remove it - would mean I'd have to move out completely in the process. I'd be willing to bet that the cost would be $30-40k just to have it removed, then add the costs of putting whatever new back (foam, fiberglass, etc) and then new wallboard, paint. It's a nightmare.

@@MrCheeto01 No. I don't need the government to pay for all of my "expensive" choices. However - the real estate industry does a piss poor job of informing buyers and obtaining disclosure from sellers regarding the presence of things like asbestos, lead paint, and other hazardous materials. It has also been a sellers market for many years, and as a buyer in this climate you don't really get the opportunity to get thorough inspections of houses if there are multiple people bidding on every shitty house you can barely afford. Additionally, governments do a terrible job of informing potential homebuyers of the probability of their new homes containing these hazardous materials, and the risks posed by them, or the expense involved in mitigating them. Also, many younger folks do not understand the building materials and practices that were used to build these older homes, and moreover - don't really have a "choice" as you suggest. They have a budget, and the market determines what areas they can buy in, and what vintage of house they can afford. It's not like they teach kids how to choose and buy a home in school. I guess they just expect that nobody will be able to afford to buy anymore? Sadly, it seems like we're headed in that direction. Our governments outlawed things like asbestos and lead paint, lead pipes, etc., all for public safety reasons decades ago - but yet, the effort to ensure that younger generations are informed about them have mostly disappeared. Why? Maybe they don't want to get in the way of the real estate bubble, and the revenue they earn from it. So now a new generation is stuck with these houses that aren't worth what it would take to either remediate/renovate, or demolish and rebuild - and the folks living in them can't afford to do either, because they could barely afford them in the first place. Anyway, I "chose" to buy a house I could afford and get out of my parents' basement and not become a KZitem comment troll. It only takes one uninspired comment to see what your choices were.

My Mom and Dad built their first home in 1975, a year after my birth. They decided to go with a heat pump. It's in Zone 5b if you're familiar with agricultural zones. Our winters are frikkin cold and our summers are hellishly hot and humid. It's normal to see 95° F with 90% humidity and -10° F with high wind. For the first decade, that heat pump was the only source of heat in the house. And this was using 1970s heat pump tech. That unit was replaced...6 years ago. What a trooper of a heat pump. Yes, it had emergency resistance heat, but it was rare that it called for it. You knew in an instant when it turned on, as the dust would burn off and produce that distinctive smell. Well, that and the big red light on the thermostat, lol. A heat pump is one of the most energy-efficient ways to heat your home, even in northern states with cold winters.

Thanks for producing such a informative balanced and accurate video about heat pumps in particular but so much else gets a mention, VRV, inverters and more. I'm a Brit who was taught by guy's, all men who had been through a war and then back into industry, we all worked for a US air heating company who was diversifying. 1970 Condensing broilers, natural gas, the manufacturing hadn't arrived. Heat pumps did arrive by 1980 as a cooling unit for cellar cooling for hundreds of pubs with below ground cellars. The heat transfer was to pre heat a first stage hot water cylinder for a constant three to one energy gain 365 days. I was told by Toshiba I installed the first Tosh heat pumps in the UK. An a/c pipework only installed the units. An electrical contractor wired, I was to make the final connections, vac and charge with some publicity shots. The installation was a mainframe computer that would never require heating forever, cooling only at a kW in equals a kW output. The ad agency went away happy and the chief engineer took me out to dinner as I was staying the night. I tried to pay but he said no quite forcibly and smiled. He said the IT manager would be paying, he thanked me being honest as he had insisted the computer room would never require heating but his !level of science the IT produced literature that the heat pump would save money.

I shopped around, and at the time, Lennox offered the most efficient system (XP25: 24 SEER), which was only $3000 more expensive than the 13 SEER base AC-only models + gas furnace every installer was pushing. Besides two bizarre hardware failures caused by bad firmware, I've been very happy with it. Paired with solar, the only cost to operate it has been maintenance. The service techs always comment about how rare and fancy this unit is, which saddens me - it should be standard by now!

I installed a 4 ton heat pump in my 1,800 square foot home, buying the equipment from a mail order place in 2014. It has worked great, and I never hooked up the electric back up heater, using that furnace to carry the air through my existing ductwork. I changed the indoor fan from 1/3 HP to 3/4 HP to increase the airflow up to 1,600 CFM to meet the needs of a 4 ton system. I can cool my house in Portland Oregon by 5-7F each hour, as the cooling capacity is oversized! But at 23F, the lowest normal outside air temperature in winter is 26,000 Btu's per hour. So the heating is sized just right! I was in a home that had a 3 ton unit with about 2,400 square feet between the first, second floor and the finished basement. It was not nearly large enough, but I suggested a 12,000 Btu unit in the master bedroom, to provide plenty of cooling there, and the cool air could circulate around the home when running both units on a hot day. The units are very quiet! The person I bought the home from said that one winter, the January bill was $400. I have never been over $135 with my heat pump. The 20 KW system is still there, and not hooked up at all! I replaced a lot of PTAC at a retirement center that I worked at. The new ones work great to about 35F, then switch to electric heater at that point. They had 75 rooms heated with PTAC's and about 60 using two Mitsubishi ductless heat pumps with two 480 volt outdoor units running all of the ductless systems. The other buildings used regular furnaces and A/C units. I installed a 120 volt ductless 12,000 Btu unit in my nephew's rental home. Not drilling any holes in the wall, I installed the indoor unit on a TV cabinet, that is about 6 feet tall, and 24" deep, 40" wide. The tubing and drain line run out a window, to the outdoor unit, and the plug comes inside to a nearby 120 volt receptacle. When he moves, he can take the indoor unit and pass through the window, then take it to his new home! Don't need to disconnect the lines to move it. Your friend with the propane furnace and A/C unit should have considered and installed a heat pump, sure it will cost about $500 more for the equipment, and the Nest or other thermostats can change over automatically when the outside air temperature is less than about 25F to propane. Yes most companies take the cost of the equipment and double it, then add the labor costs, and add about 15% more for profits. So the $6,000 system will cost about $6,000 more to install than a $1,500 system that is installed for about $4,500 total. Your San Diego friend would be happy with a 18,000 Btu ductless heat pump in the living room, and then leave the doors open to the other rooms to keep them cool. Perhaps install a window A/C in the bedroom if required at some point, but hey, Sand Diego the nighttime temperatures is OK. And with 0 hours less than 20F in San Diego, and less than 40 hours per year less than 35F, they can get away without any back up electric heater. The air duct insulation on the San Diego house - if built more than 30 years ago might not have any insulation or R-2 insulation. With undersized air ducts, go for the heat pump that is about the size for the air ducts that you have. Then install a ductless system in the living room to handle more of the heating needs of the home in the very cold days, or very hot days. And the ductless system that the unit will use a lot less power per 100,000 Btu's of heating or cooling than the central system. And no air loss from the air ducts! Some systems can lose a lot of heat from the air ducts.

These heat pump videos are pretty great, Alec, but are mostly from the point of view of regions where refrigerated AC is very common. Here in the Southwest USA (NM, AZ, West TX) refrigerated AC is comparatively rare and seen as superluxurious, with evaporative cooling and gas furnaces being ubiquitous here in the domestic space (excepting, of course, commercial AC installation), but refrigerated air is also becoming a little more common. It would be interesting if you could make an episode comparing the two types of cooling (mostly in _arid_ regions), their respective resource usages (one uses a load of water but can plug into the wall, the other _makes_ water but drinks power like no tomorrow) especially considering the SW megadrought and potential power generation shortages, the pros and cons of replacing one system with another, and what it would mean for a heat pump installation instead of gas.

One of the largest markets for these split systems is RVs. Lots of full time RVers are installing solar panels on their roofs and lithium batteries to store that collected energy. In this situation the efficiency available in split systems can allow AC or heat to run all night on the stored energy, especially if you only really need to run the head unit in the sleeping space. Add in the fact that full time RVers usually follow the moderate temps because their homes are, you know, on wheels, and you have a perfect use case. Another excellent use case is when homes or living spaces are expanded. It is much easier to add a mini split to a converted garage or attic space than expand or replace an existing whole-house system. Once folks have good experiences with the units in their expanded living space, they may add more mini split systems when it comes time to replace their existing whole house system.

One very real problem with using ductless systems in small homes is the limited lower end of indoor unit size. It is pretty much impossible to find a small enough indoor unit for many applications. And those lovely modulating inverter systems? They can only modulate down to 25 or 30% of rated capacity. This means that if you have a multi-head system you can't efficiently air condition only a single room to save energy. Modulation and over-sizing also come into play when using the heat pump for air conditioning. If the system is oversized, then it doesn't dehumidify effectively. You end up being forced to have an excessive relative humidity or you have to over-cool to get a desirable RH. My _guess_ on the HSPF number being lower than expected from the COP is that HSPF includes energy consumption at partial load, at no load, and when defrosting; not just the COP during rated operation. I'd love to collaborate on a deep dive into HSPF, but I bet one of your other readers actually knows. On the cost of installation, do keep in mind the concept of 'mark up'. Professionals generally charge for their time and some multiple of the cost of the hardware being installed. Think about two systems that take 10 hours to install. You might think that the total installed cost is 'wholesale cost + 10x hourly rate'. But that doesn't include the potential cost of something going wrong. People make mistakes, they are after all human. Responsible professionals fix their own mistakes. But to stay in business they have to charge enough to be prepared to fix those mistakes. That means that they need to charge more to install more expensive hardware, even if the effort is the same. Jon
