    Pls Help Choose a System (specifics included)

    Replacing our upstairs system (2 tons) in our two-story 1960s era house in North Texas (hot, fairly humid in the very long summer, very little time when heat is really needed during the year - but it is needed every winter at some point). We do not anticipate living in this house forever - probably will move within five years.

    OPTION A - Carrier Comfort 16 R410a, single stage
    Condenser - 24ABC624A003 (single stage)
    Furnace - 58PHA045-1-08 Boost 80 (single speed)
    Coil - CNPVP3017ALA


    OPTION B - Trane single stage
    Condenser Trane XR15
    Coil - Trane AHRI
    Furnace - Trane XT80


    OPTION C - Carrier Performance 2-stage R410a
    Condenser - 24ACB724A003 (2-stage)
    Furnace - 58CVA Infinity 80 (variable speed)
    Coil - CNPVT3014ALA


    OPTION D - Amana two-stage
    Condenser - Amana 16 SEER Performance 2-stage
    Coil - Amana
    Furnace - Amana 80% Two-Stage, Variable Speed, 70,000 BTU


    Thanks in advance for any advice you experts can offer! We understand the importance of good installation and these providers all have excellent Angie's list ratings (and lots of them).

    Last question - how much difference in our electric bills will a two-stage versus single-stage system make in our climate?

    Which company did a load calculation? The amana is almost 2x the size of the carrier's. 2 speeds doesn't necessarily save energy, however 2speeds are only offered in higher efficiencies and will probably lower your bill over what you have now.

    Let's assume these are all 2-ton systems. I've been getting quotes on systems for upstairs and downstairs, so that is where the confusion on the sizes is (my fault).

    Our current systems are old and very low efficiency. We are going from 8 SEER to much more efficient. Our electric bills are currently astronomical, so any change will be a huge improvement.

    How much less electricity is consumed on a 16 SEER versus a 13 SEER?

    Also, how much difference in electricity consumption does it make to have a two-stage system versus a single stage system? Is it more of a comfort/noise issue rather than an energy consumption issue?

    ETA - all the systems we're considering right now (above) are 16 SEER.

    What size area?

    I like the Trane best.

    What size furnace was quoted?

    The XT80 has a high eff blower motor.

    Post back with the matching AHRI matching directory number.

    And for info, two stg condensers are more about comfort than operational savings.

    IMO

    What size living area for the zone system will serve?

    You are being oversized on the XT80 furnace.

    I would drop down to the 60 KBTU size.

    Ask dealer for the matching AHRI system number.

    You are being quoted a 2 or 2 1/2 ton AC condenser?

    What size furnace and AC are you replacing?

    Post back.

    Ask if they do a load calculation. You stated 2 tons is working fine....why are they putting in a 2.5 ton.

    And by the way...I like Carrier/Bryant but don't bring up brands because the installation is more important

    ??????

    So If I read correctly we have an upstairs and downstairs system? And 60K would be okay for the upstairs system? The 60K would probably heat the whole house (on a snow day)

    Thanks so much for all the advice!

    Could you guys please explain to me why you would reduce the size of the furnace? What difference does it make to have an 80 furnace versus a 60?

    I apologize for the confusion. We have two systems. Downstairs is 2.5 ton. Upstairs is 2 tons. We have been getting quotes for both but have decided we are only replacing only the 2 ton system upstairs for now. I have no idea what the upstairs furnace is now - other than old an very inefficient (oh, and cracked).

    I totally sweat these decisions, man. I'm hoping we can choose and be done with this today. I'm ready to move on after a week of collecting bids, discussing with people, researching, etc.

    Thanks, again, for all the help you guys are giving!

    How about we don't "assume it's a 2 ton"

    OP, what exactly is your current equipment upstairs and downstairs???
