    New HVAC system

    Hey Sirs!
    I decided to select the TRANE HVAC 16 SEER System to replace my existing 08/05/2005 Manufactured 10 SEER Carrier system. My 2006 SFH is built in Northern Virginia, finished with two levels (3,560 Sq.ft) and I plan on adding a finished basement (800 Sq.ft) in future. Is it worth the money to move from 2.0 ton to 2.5 ton for Attic and 3.0 ton to 3.5 ton for Basement? Will the current Air Ducts handle air flow with an increment of 1/2 ton? Did any one claim the home insurance to cover the old HVAC replacement costs? Any advantage with the TRANE over Carrier brand. Appreciate valuable suggestions! Please comment on any mismatch Trane system pair.

    Bigger is better doesn't work with HVAC equipment. When buying shoes, do you buy a pair a couple sizes larger because bigger is better? No, you buy the size that fits you. You need the the equipment that is sized correctly for your home.

    you would need to see how much humidity is in the air/foundation and foundation walls in your basement..and make sure it is water tight.you should already have a geothermal temp. the basement will not need much except dehumidification with excess humidity if its not water tight. the cooler return air from the basement could possibly assist you cooling load upstairs...some basements could have 12' ceilings and others are 6'...you home load calculations will tell you what you need...without it you are just guessing at this point...

    do it the right way...have the load calculation done..then return with that info..

    NOVA is not a city that I can find in Virginia.

    First level is a basement which implies it is fully underground IMO. To be confirmed.

    A fully underground level probably does not have any windows. To be confirmed.

    An Air Conditioned/ Heated basement with eight diffusers ( registers) and a separate A/C system is not " UNfinished. "
    .. i.e. __ Block wall with R-13 insulation? or _ _ ?

    Choice between Hybrid System(s), Heat Pump and/or Furnace
    depends on the locale / climate, natural gas and electric rates along with the
    ACCA Manual J & S calculations.

    Furnace may be selected for main level
    and not selected for the basement.
    Heat strips may be selected if electric rate is < $0.11 / kw-hour
    and natural gas is > $1.00 / therm.
