Nothing to do with real estate on this one, just a good old public service announcement. Like most folks the outside condenser unit at my house, which was installed with a matching air handler, is tired. Being “thrifty” I would like to change out JUST the condenser and keep my air handler. I started to Google the question, reading and watching You Tube. Lots of broad strokes and warnings but how would I KNOW one that I buy off say Facebook Marketplace will work? I now know. I got a clue from and AC tech and looked into it. The answer is AHRI
Get the make and model number of your air handler, the inside component. Then go to the AHRI website. Do a search by the model number and it should return a list matched systems to that component. It will even give the SEER rating of the system. Not surprisingly if you have say a Trane system the results will be Trane (or American Standard) matching condenser units. Still, now you know for certain which units will work with that air handler. And what to buy and have installed that should work.
