r-22 dry heatpumps?

[movielife1234]

i have a new property owner with which i do work on the side and he is in need of heat pump cheap and fast. first off let me give you guys my background. ive been in the trade for 11 years now but just recently jumped over to commercial/industrial about 2 years ago. I have my md journeymens and im cfc universal as well as nora bronze certification. so im kind of out of the loop with some new residential stuff thats out.... ill try to make this easy, i could not get into the property due to the tenant but i know its a old lennox airhandler. the heatpump is so worn i cant make any info out. i know it should be a 2 ton system. so my question is are these dry heatpumps compatible with any brand would i have to replace the metering device and how well do these systems work? I would rather replace complete system but he's in the rental game in baltimore city not somewhere you want to drop alot money.. thanks for your help

Since the dry unit is 13 SEER you could have issues with the size of the old indoor coil being too small. You might end up having to change refrigerant amount at change of mode.

How many free service calls do you want to do a year. What size line set. Is it an IFC/RFC(not sure what its called anymore, Lennox used the liquid line as part of the metering device, don't recall if it was used on heat pumps also). If so, you'll be changing out more then just the condenser.


Baldie, when is Eric going out to that ladies house.

First lesson in heat pumps - Mismatching brands = bad. Mismatching brand AND seer very bad. mismatching brand seer and improper lineset size even worse. Will it work? maybe. Will it work in different seasons? As beenthere says, you may have to work on it often. too much freon, too little freon, repeated service call costs
Best to do it right and get a good long term result and avoid the headaches, will save money in the long run.
