    Hmm

    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

    Is this a heat pump or an electric furnace?

    A heat pump would have the setting 'Em Heat' available on the thermostat.

    Mechanical Designer?
    Is that what we used to call a draftsman?

    What did your contractor say was wrong with it?

    I can't imagine any professional that would not be able to properly troubleshoot an electric furnace. You need to find a different person to take a look at it.

    I assume it was a electric furnace since it has coil type heating elements in the airpath. (I've seen them myself)

    BUT, it does have a 'EM HT' option... ?? I thought if it had a heating element, then it was conventional electric.

    No.. it's not a draftsperson... But I do CAD in my job.

    I haven't had anybody else look at it. My wife and I are confident we can troubleshoot it (she's an electrical enginner by degree, controls logics programmer by trade) but we've never been educated in HVAC at all.

    Some of us Mechanical Designers do way more than just drafting. We might be the person inspecting your job, reviewing your submittals, or answering your dumb questions the day before a bid is due. If you called me a draftsman or questioned my professionalism, I would be insulted.

    electric furnaces dont blow hot air through the registers , they just blow warm air. On a gas fired furnace the registers will blow hotter air than what you have. I think that your thermistat is satisfied, does you feel good when its 70 in the house? electricity went up in price and I think there is no problem here

    o.k... let me say it another way.

    Now and then, the air is warm, most the time it's cool air, and the fan NEVER turns off.

    Is that normal?

    NO.

    Have your wife get out her multimeter and the schematic and start checking things...

    See if the outdoor unit is running in the heat mode,if it is it's a heat pump.

    Heat pumps ,at low temperatures can run virtually all the time,the strip heat can cycle on and off to provide the extra heat needed to maintain the temperature set point.

    Depending on the outdor temperature ,it may be normal,give us some more info..Location ,temperature,model numbers,etc..

    However,this is not a DIY site,see the rules.

    It has been in the 20's and 30's here during this learning process. Looks like pro help may be needed unless we determine this is normal.

    Thanks ya'll.

    I apologize if you are feeling insulted.
    I never intended to insult you, or your chosen profession.
    I just simply had not memorized the Dictionary of Titles.
    (I've never placed much importance on titles anyway.)

    "Mechanical Designer" is a new term for me.
    What sort of coursework allows one to display that title?

    My goodness...I just wanted to learn why my fan ran all the time, and look what it started..

    not that is all that important, in my carreer, I work with engineers to get designs done, and manufactured. Sometimes I have to do some drafting (I'm not above that), other times someone does drafting for me..

    heck, for the right money, I'll sweep floors and you can call me whatever you'd like.

    Now, for a heat pump, with outside temps in the 20's and 30's, will I find that the fan runs most the time? or is this a problem I need to get professional help to fix? I don't mind either, I just need to know 'cause right now I'm at a loss.

    Thanks to the good guys who care.
