I apologize, but when it comes to HVAC, I don't know much, and that is why I am here. To learn a few things so I can hopefully become someone who can do more than change my filter now and then. I'm having a problem with the electric heater in my house. Here are the symtoms that drive me crazy.

1) VERY high electric bill.
2) Fan seems to run all the time (not 100% sure, but I am 99% sure of this)
3) Air is only warm sometime. (like not very often, but when it is warm, it is nice)
4) Thermostat is set on 'auto' at about 68-70 degrees.

I have a theory that someth'n ain't right. I was under the impression that these unit run when it is warming the unit, then has a short just fan time to cool the element, then the fan stops. Therefore, most the time the air is blowing, it would be warm air. (until that brief time before the fan shuts off)

Help me, I want to learn, but am at a loss..

Thank you
