    Total replacement - Need informed help

    Location - Knoxville, TN
    One level - 1200 to 1400 sqft

    Two days ago my AC unit died, tomorrow I have 5 installers coming for estimates. What I have (had) was an AC unit outside & an elertic furnace in the attic. The system is orginial (25 - 30 years old) so I am going with a total replacement.

    I'm not a big fan of heat-pumps (never warm enought in the winter). So I am looking at replacing with the same type of system.

    If I do go with a heat-pump would the ducks need resizing?

    After I get the estimates I will add this with more information or what information do I need to supply?

    Tia

    I would make sure that you scedual the sales guys so they are not tripping over each other. Makes things hard. DO NOT show them each others estimates, or ask about what the other guy said. Wait until you get all the quotes side by side then come back here. Brand is not as important as a good install.

    So your price shopping ha? no matter what we say if you have 5 companies coming for estimates you are probably looking for the best deal not the best install or equipment, JMO.

    Just what I was going to say (about insufficient timing).

    I hope they don't come in company-identified vehicles. Might be a little embarrasing.

    Am I "price shopping" - It matters but NO, different dealers, different brands, and I am assuming different suggestions. I have setup the installers to come at 2 hour intervals.

    I seldom ever go with the lowest estimate - prefer to do it correctly and only have to do it once.

    No assumption needed different suggestions are pretty much a given in this business.

    Your ductwork may or may not be sized correctly for a heat pump.
    Newer heat pumps have a higher air temp then the old ones did.

    I left a sales call once and there was five other guys waiting behind me to give a pitch.

    I looked at my schedule and discovered that the guy I just left had made four appointments that day with us. One for each number in our ad.

    Sure hope the OP didn't pull on of those .

    Hybrid ~ Heat

    That is a fancy word for Duel/Fuel system.

    Carrier Hybrid heat uses a gas furnace with heat pump that keeps indoor temperature comfortable down to 25* outdoors , then gas furnace comes on and supplements heat after that set-point.

    Check it out you might be surprised at the newer systems and the heat that they produce vs old style heat pumps..

    Hmm What is Warm Enough? 100 110 120'F

    Dual Fuel system (gas furnace + heat pump) would be the best operating cost and comfort option in TN with low electric rates and relatively mild winter temperatures.

    Air should be warm enough > 80&#37; of the time with the heat pump.
    "Warm enough" should also address the low winter relative humidity.

    Switchover to the gas furnace can be set to your wishes.

    ... ... Curiously, ...
    Why don't people frequently mention that the A/C air is not cool enough in the summer ?

    What is Cool Enough supply air from the HomeOwner's perspective?

    No Gas

    Gas is not an option - Unless I want to pay the local utility company to run a line down the street to my address (over $10,000).

    Just had a little bit of sticker shock on the first estimate - Will post all estimate information this evening after I get them all.
