Great video! 👍 I've been an ASE master tech for a while and changed over to working on Heavy equipment. What I noticed is dirt is the biggest culprit of poor cooling. So definitely checking filters and airflow on condensers and Evaporators is key.

On pressure washing, use a 35-40 degree nozzle and spray coil straight on and through. Spray with the coil and not sideways against. You can also spray from the top straight down on the front side. Always be careful, though.

What could cause an evaporator to frost over? I'm a heavy equipment mechanic and have been fighting with a machine with this issue, the evaporator is clean and pressure is spec as per Volvo.

Low charge, or freeze switch is bad causing compressor to never cycle, or evap plugged not getting enough hot air blowing across it some things to look at

Awesome video. I have a few questions I hope you can help me with. I have been working on barko log loaders and the evaporator is under the seat, would you have to remove it to wash it out? Also I have had several restrictions in the lines and replaced the dryer and expansion valve. I pulled a vacumm on the system, recharged but all 4 of them I've done I couldnt get the suction pressure higher than 18-22 psig. They havnt been freezing up but still seems like something isnt right. Do you ever have to adjust the block style expansion valve?
@jimguzzo8661

18-22 lbs is not bad, if the rpm’s on the motor is 1500 or so. Yes, you may have to pull the seat to pressure wash evaporator, blowers and all. If the evap has a blanket of dirt over it, your suction pressure will be low. Get it clean and start with that. Also, don’t get mis directed with adjusting thermostats. That is not your problem! A log loader is in a very dirty environment. Make sure the filters are clean too. Let me know what you find. What part of the world are you? Let me know.

Three of the loader are stationary electric with a separate 3 phase motor turning a automotive style AC compressor but I honestly haven't checked the speed because there just one speed all the time. I just thought that if the pressure was that low that they would freeze up from being under 32 degrees in the middle of the evaporator. It was the expansion valve / TXV that i was curious about adjusting. I havn't tried to adjust but I had the thought in my mind because I know they're adjustable in stationary ac and refrigeration. I will pull the seat when i get a chance to see what the back side of the evap looks like. I sprayed coil cleaner on front side of evap and rinsed it out on the last one and could feel the blower pulling more air but pressures seemed to stay the same. There isnt tags I've found that state how much refrigerant to add to the system, only has badges that said badger truck refrigeration. I guess I might could try to get into contact with them to see if they can tell me from the model number. Thanks for the help! There isn't much info on the net about heavy equipment AC systems. I'm from east tennessee.

I understand better now. The best way to charge a system, if there’s no site glass, is while adding Freon, hold the suction line with your hand, at the compressor and you’ll feel it get colder and colder. When you feel it cold to the bone, that’s it. Be careful and watch your suction pressure and charge till cold. If you get used to doing this, you will always be right on. Also, be careful charging a prescribed amount from the factory.. They are often wrong! Let me know how you come out. Jim

Dustin, You can also feel the suction line at the accumulator, if it has one, or the suction line at the evaporator.
