Roger G asked:
My heat pump is set for heat, but late in the night or early morning, while the heater is on, it switches itself and blows cold air. A few days this past week, it seemed to me that it was blowing cold air for about 30 mins, then would switch back to heat. Is this normal?
I live in Phoenix, AZ
Also, the unit was new and installed in 2005. House also vibrates when the unit is on.
I contacted them about 10 days ago when it started to do that. The guy was up there for 20mins. He said everything is fine. I have had a lot of problems with Sun Energy, Inc. They had an advertised price in the paper. They said that it will be a Ducane and it is a divison of Lennox. So I thought it would be a good system. So I went with them. This year I had the blower wheel and 2 thermostats replaced. Plus I had freon added 2 times since 2005. The repairman from the company says that the manufacturer didn’t put enough freon the first time. I am considering contacting someone for help with this company.

The reversing valve is relatively new contact you original vendor there may not working or booster is kicking in place.
The fan on top the outdoor unit wont be running intervals usually when it goes into defrost cycle is possibly going into defrost because the fan on top the fan on top the cold air until defrost after timed running intervals usually when.
