I have an issue... I purchased a prefab home and it came with an electric havc system installed... My ac works fine in the summer, but in the winter it appears that it only runs in auxilary heat. The air coming out of the vents is somewhere in the order of 120 degrees, all the time. Even in mild weather - whenever the heat is on. This of course leads to the unit kicking on and off very frequently and high power bills. My thermostat only has a cool, off, and heat setting, unlike the older models I've had that have 4 settings - so I'm lead to assume that the regular and aux heat modes are supposed to be automatic.
I do know that the outside heat pump/condenser does NOT kick on when the heat is engaged regardless of outside temperature... But since the ac works I'm assuming its wired wrong? The unit is only about 1.5 years old and has done this since day one... I opened the thermostat trying to find the model number, which is 1f86-337, and noticed that the gas/electric switch was turned to gas.... So I turned it to electric but there wasn't a change and the outside unit still did not kick on. Overlooking of this switch tells me the tech had his head up his rear though..
Any thoughts on it being something simple or will I have to call it in?
