My husband and I had a 14-seer Ducane installed 6 weeks ago and it is blowing only hot air now. This started yesterday. Tech came out yesterday and can’t figure out what is going on, he has two theories, 1) the suction valve is too small (have a 5/8", he says it needs a 7/8") or 2) the expansion valve is bad.
He called the mfg. this morning and they said to turn off the unit for 2 hours and then turn it back on as this would allow the suction valve to do whatever it does to get back to normal. Well, that didn’t work. It is over 100 degrees outside and 88 degrees in the house…I’m dying!
The tech is stumped, he is coming back over soon and I would love to help give him some suggestions…has anyone seen this before? If so, what did you do? Any other ideas I could give the tech?
Thank you in advance!
