Thermostat

We have a 3 1/2 ton Trane heat pump that works for a few weeks and then quits. We had a repairman out twice now and the first time he replaced the compressor and the control board on the outside unit the next visit he replaced the transformer on the inside heating unit. Each time the unit worked again for a few weeks and then quit. We are beginning to think he really doesn't know what is wrong and hate to call him back. HELP!!!

 

Wow, you must have paid quite a few bucks to have that work done. And it still doesn't work? The bad part about calling someone else is that they will have to start from square one and will not give you credit for any work that was done previously. If you call the same guy back, he will know what he has already done and possibly cooperate on future repairs. On the bright side, he has replaced the most expensive parts in there except for the reversing valve. That's all the help I can give without knowing more or knowing what made the tech replace the compressor.

 

wow, if they will not work with you to fix it (talk to the service manager or owner) do not hesitate to call someone else. they do not have to be trane dealers. either you have several problems or you are getting service from a "parts changer"

 

You dont say how old is this unit???? You could call trane there and talk to them. Like hvac4u said this guy could be just a parts changer till he gets the part that dont work ED

 

Yikes, I've been in the HVAC buisness for 45 years and when I hear stories like this it makes me want to throw up. If this is a reputable company call the owner or service manager. You should not have to spend another nickle. "Hint" TRANE heat pumps are prone to locking on out on evaporator coil freeze stats, especially if they are over sized. Unfortunately this is a common practice. Whan it come to A/C, bigger is never better. By the way, KField is right, and the reversing valve could very well have caused the supposed component failures you have already experienced. As I said, pick up the phone and scream...
