Let me start over. I was thinking they could either A)replace a-coil as is and stay with R22 which is going to cost them a bunch to recharge. (something like $600 quoted to them just for recharge, I think) or B)replace a-coil with one for R410 and then of course they would have to replace the condenser in the heat pump outside to match. It sounds like you guys are saying that you don;t replace the condenser alone but the entire unit. Or of course C)replace the heat pump outside and the air handler inside which is going to be a massive job that I think will end up well over $6k or even $7k
I want to recommend option B if it is at all feasible, since in my mind I was thinking they could get away with a job costing closer to $3k and have basically the same result as option C but without the brand new warranties.
OK, let me know if my thinking is crazy talk.
OH and I'm almost 100% certain Goodman makes an R410 a-coil that would fit this old air handler. |
Just to verify for you. You CANNOT use a 410a coil with a R-22 condenser/compressor. The bulb that the TXV, expansion valve, uses to control how much refrigerant the valve lets by is charged with 410a refrigerant. That bulb will either allow too much refrigerant by or not enough. The bulb is strapped to the copper lines in the coil. It is suppose to sense the temperature of the refrigerant flowing through the coil and open the valve the proper amount. Those temperatues need to be the same for the valve to operate correctly. Those temperatures will not be the same if you put 2 different refrigerants together. This will prohibit the unit from working correctly and cost them even more money.
