My heat pump uses R22 refrigerant. It is currently connected to a KEEPRITE electrical furnace which needs to be replaced.
A technician from a LENNOX dealer will install a CBX27UH air handler (not a CB27UH) to replace the KEEPRITE. As you know, there are two models available: CBX27HU for R410 refrigerant and CB27UH for R22 refrigerant. The technicain told me that to make my R22 heat pump compatible with the R410 CBX27UH air handler, he will simplly install a valve, it will be ok.
My question is: Is the CBX27UH model (R410) really compatible with my R22 heat pump? Why does not he install a CB27UH for me, that way we are sure there is no problem for compatibility?
