Home A/C blowing hot air afte compressor fan replaced?
Question:My A/C unit was blowing hot air and a tech replaced the compressor fan (it was not running). At that moment, the air was coming out cool. However, when I returned home from work, the unit was again blowing warm air. Is this a compressor problem and should it have been diagnosed on the first visit? if so, what is the price range for this part?
Answers:
was the outside unit running when you came home and found your home hot...if yes, was compressor running, if yes then low on freon, if no then 1 bad capacitor 2 bad compressor.it would be very hard to diagnosis if the compressor ran while he was there and if it cooled while he was there..need to call him back and get him to check the unit again..if it was something he overlooked you should only have to pay for parts...if it is something he could not detect while there first time you will have to pay for another call plus parts.the company or him should stand behind their work..
maybe it had a leak and all of the coolant leaked out
sounds like it may need freon. The guy "should" have checked that but maybe he didn't. Just a guess.
Dig out the credit cards... sounds like the compressor itself. I had to have a whole new unit installed a month or so ago too.
Check your coils... they might be froze up. That could be why you are getting hot air. Since your fan wasn't working, and if its been froze up after a new fan, is probably low on freon...or whatever coolant its using. Low on coolant... probably a bad compresssor because your fan hasn't been working.
have the freon check .
You might be out of coolant.
And yes, it should have been checked
on the first visit.
Ok...if your a/c is blowing hot air, that means your indoor coil is not iced up, if it were iced up you would have no airflow at all. Now it was working when the tech left but now it is not, he changed the CONDENSOR fan motor, so check the condensor fan motor while unit is running, is the fan spinning? if so, the motor should'nt be the problem. The outdoor unit could be tripped on a hi or low pressure switch and may be holding the unit off, or the compressor might be tripped on internal protection(usually will happen if refrigerant charge is low, compressor will then overheat and trip).in a nutshell call the service co. back and have them recheck it.
Keep in mind if you do have a compressor failure now, it may be a result of running your air conditioner with that burned out fan motor, you may have cooked your oil and it has now locked up or burned. This does happen sometimes and you cant necessarily say it should have been diagnosed on the first visit, its a new problem that occurred due to a previous one.
good luck and hope its not a compressor failure, if so...replace the entire condensing unit rather than just the compressor, its better in the long run dollar wise.
It prob need a shot of freon too may be leaking out
