    Confused

    Ok now I really need expert advice.

    Current Models of A/C, Coil and furnace are as follows:
    Allegiance 10 7A0048A100A0 manufacture date 9/96
    American Standard TXHC41A4H9A0 MFR DATE L32
    Consolidated Industries HBA100ND5R Install date 10/3/96
    (motor is a Fasco no. 7021-6376 and Honeywell is on a few other parts of the furnace)


    Hvac Load sheet shows I need about 38,000 BTU for the house. So Im going with a 3.5 Ton unit.

    What are my best options?
    If I keep the furnace will that restrict the SEER rating and how well a New outside unit and coil runs?

    Is it best to replace all 3 items?
    12 SEER or like a 16 SEER

    I live in Houston

    Heat pump vs furance?

    Don't replace anything, just fix what you've got. Besides you won't be living there that much longer anyways.

    The furnace is fine as long as you stay with single stage outdoor unit and don't want super SEER which requires a variable speed blower. Key is matched indoor coil. If you stay with American-Standard or Trane, you may be able to keep the existing indoor coil and just add an expansion valve to it. If you change brands, you should have new indoor coil. If you want to take advantage of the extra dehumidifying capability of a variable speed blower, that would be nice in your area.

    We have some Houston area contractors on here who could help you. Where's Al when you need him?

    XL16i 4-ton or equal is recommended for stated conditions.

    48,000 Total Capacity is generally about
    36,000 Sensible Capacity

    explain a heat pump vs ac/coil and furance?


    heat pump for places that only need a little heat in the winter?


    Should they be cheaper then buying AC and furance?


    thanks again

    Question

    another question


    with the mismatched 4tom outside unit and a 3.5 ton coil and the AC being 10 years old do you think it is still running equal to a 10 SEER or more like a 8 SEER as one contractor stated
