    Trane System w/ 80% or 90% Furnace

    Thank you all for the feedback on my other posting. I feel wary of Amana even with the Lifetime warranty so I believe I will be going with a Trane system. Here are the 3-ton 13-seer specs: A/C Condenser XR80 - 4TTR3036 , Coil 4TXCD36 matched with a XL80 Furnace TUD1B080A936.

    The question is would it make since to use the Atlanta Gas Light Rebate of $250 to upgrade to a 90% AFUE Furnace? What would be the time to recoup the costs?

    With gas prices going up would it be worth upgrading the furnace instead of going with a dual fuel combo?

    Personally I'd go dual fuel. In your area, you'd spend little time on gas.

    Dual fuel makes more sence then just upgrading furnace efficiency.

    How many times must one fix something before it is fixed?

    Depends on pricing

    I would find out price of gas and price of electricity. If gas is cheap, invest into high efficiency. It electrical rates are simmilar or cheaper, go dual fuel.
    Do it right the first time.

    if i were in atlanta I would probably go with a heat pump and an 80% furnace with a variable speed motor

    you already have to have AC, so a heat pump should only cost marginally more

    I probably wouldn't invest in a high efficiency furnace- it will only be used when it starts to get close to freezing, which isn't very often in Atlanta, so having a furnace that uses 10-15% less energy won't make much of a difference
