My HEIL unit will sometimes blow cold air, like this morning when it is 27° outside. If I turn off the main breaker in the house, and then turn it back on, the heater will blow hot air like it is meant to do. Anyone have any idea about this? The folks who installed it in 2001 have come out and tried to figure out the problem but never did. At first they thought it may have been a circuit board malfunctioning; but, didn't ever find the problem.
Has anyone had any similar or the same problems with their HEIL Central Air & Heating unit, if so I would like to hear what you have to say about it. Thank you.
