Bergmann and Spohn... the best of the best. HVAC is truly a lifelong practice. I'm 64 and still in the field and love what I do. However, it's frustrating reprogramming the technicians and installers under my wing to throw out the lies of their old, inadequate methods.
Damn, just a homeowner here that hired a terrible HVAC guy to install our new heat pump. Hack is definitely the correct term for this guy. I’ve corrected everything on the system I can, air leaks, insulation, room balancing, verifying static pressure to help set fan speeds, and so much more, but I can’t verify he flushed the line set with nitrogen and properly evacuated it. I’m worried I might end up with a situation like this down the road, that will cause the early failure of our system. I’m contemplating finding a new guy to drain, flush and refill the system. More stress than I need.
Bill I can not believe with all you know you had a handyman install your unit. You are good friends with JIM BERGMANN, BRYAN ORR, the few of us that are pretty good at this!!! You could have called ANY one of us and we would have flown out and done it for free for all you’ve done for the industry!!!! Leaving your house system to a handyman????? Mind blown!!!! 🤯
Square feet is not the only variable that determine system size. A very well insulated and sealed home may need very little heating/cooling. Not every house needs a 5 ton unit
Not sure why you say you cant clean the system up after acid, and who paid for the entire system changeout? The manufacturer wont, the guy who put it in wont. I will typically cut the system into 2 sections at the least,some package units/rtus,ect maybe more sections, and flush with rx11 as well as add a scavenger and honestly that has worked very well almost always,but ill still let that run for a few days then come back and replace the drier,refrigerant and add a small amount of scavanger for good luck on large systems. Ive gone back and tested to find no acid. It can be done.
@@HVACRTECH-83 it’s because of the system type. The metering device is in the outside unit and there is no line between the condenser outlet and the metering device inlet to install a liquid line dryer.

Great video and very informative 😊
Thanks for your persistence in getting the message out.
I think it is starting to sink in

@@frankgall6 it was contracted by the builder. Not Bills call.
Awesome info. Enjoyed the entire video. But hold on. Your house is how many square feet and you have one 2 ton system. 😮

@@phamlam3720 I agree. It’s just amazing the amount of square footage and such a small unit.
Triple vac :]
