    11.5 EER, 8.6 HSPF, 15.5 SEER. I did not find this on AHRI either--had to look at Carrier's performance data table. Carrier makes a nice system. Hopefully you're getting the Infinity controller. Given the efficiency of the furnace, you'll qualify for the tax credit (30% up to $1500).

    Thanks Ryan,

    Yes I am getting the Infinity controller.

    I thought I read one time that you had said something about the small furnance - is it too small.

    Furnace sizing is determined by calculating your home's heat loss. You can ask your dealer about this and how he arrived at the sizing. That's a 40k furnace only but it can deliver the airflow needed for the 3 ton unit (-14 = 1400 cfm). I'm not sure why it isn't listed on AHRI.

    Thanks Ryan - now I know what the 14 means - I did see 14s' and 20s' = 2000

    Ryan or anybody

    Would a 58MVC 60 -14 change any of my ratings.

    Thanks

    The 58MVB040-14 is a 17 inch wide furnace, but the CNPVP4824 is a 24 inch wide coil. Why is the contractor proposing this? I have a CNPVP4821 (21 inch wide) on top of one of my 58MVC60-14 (17 inch) furnaces. The contractor made a transition duct between the two. You could also use the CNPVP3617 coil which is 17 inches wide and requires no transition (I have this set up also).

    Mike,
    The 040-14 is 24" wide, and the 060-14 is 17" wide. No issue with coil width here.

    M&B,
    25HNA636A30
    CNPVP3617ATA
    58MVC060-14
    11.5 EER, 15 SEER, 8.4 HSPF

    It does qualify for the tax credit because the furnace is 95% AFUE (as long as its in the upflow position which I assume it is).

    Thanks Mike,

    I do not know yet and as you can see Rayn did not say anything about the width. You are saying the coil is wider than the furnance.

    Is there a better coil that will not lower my ratings and fit?

    Thanks

    For which setup? For the setup I listed with the 58MVC060, 17" is the width you want to be flush with the furnace, so that is the best coil option. For the 58MVB040, 24" is the width you want and so I believe they quoted you the best coil (4 ton) there.

    Ok, I am a little slow - been looking at a lot of #'s. I see the coil # now.

    Thanks Ryan

    Since you have a heat pump for primary heat source, really no need for the 3 heating stages of the 58MVC. The 58MVB should be more than sufficient with 2 stages.
