    Is this too much hardware?

    My 1500 sf house, 2 floors, Good installer says:
    Carrier 16 Seer 2 Spd HP
    Variable Speed handler
    change to 2 zones
    Is it worth saving $1000 each to cut back to 14 Seer 1 speed HP
    and/or stay with single zone?

    I thought you said it was 1700 sq ft.

    Do you mean 2 16 SEER units.
    Or 1-16 SEER unit zoned.

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

    You have not given enough information. I owned an 800 sf home that ran through 1000 gallons of oil per season in 4500 degree days. You can't project energy savings without some notion of what your energy cost is over the useful lifespan of the gear. So you can't make informed choices without that data. If you save 10 % off of a $300 yearly expense, it's not the same as saving 10% from $3000 yearly cost. At $3000 yearly energy expense, better equipment will pay back even if you finance it so long as you live there for a while.

    If your looking for comfort. I doubt you'll have a complaint going with the Infinity 2 stage and zoning.

    what size Carrier Infinity 16 HP?

    has your dealer performed a Man J heat/cool load calculation?

    what size are you replacing?

    has ductwork been checked as to size, condition, supply/return?

    I am replacing 3 ton with 3 ton and certainly the infinity 16 will do a great job.
    A york 15 Seer will give me better heat at a lower install cost here in Boston area.
    I calculate the saving to be about $100/year for each SEER number so payback is a while after the jump from 10 to 14 or 15.
    This is like buying a car without being able to drive it

    Thanks to all of of you
