    Please comment on my proposed system

    This is an add-on to my existing 7-year-old Heil 80% 5-ton furnace that I will try to get derated to 4-ton if possible. I've tried to come up with the most cost-effective solution to meet my needs. The cooling load has been professionally sized by two contractors at 2.8 and 2.9 tons, and my own HCAV-Calc results agreed with that. Using the heat pump will reduce the usage of the somewhat ineffecient gas furnace. We need humdification almost year-round here (Albuquerque NM).

    Rheem RPNL026JAZ 3-ton heat pump condensor
    Rheem RCFLHM3621AC 3-ton coil
    White Rodgers "Big Blue" 1F95-1291 Thermostat
    White Rodgers F145-1378 Outdoor Temperature Sensor
    Honeywell TrueSTEAM humidfier controlled by the 1F95-1291 Thermostat

    I'd like to oversize the coil by 1/2 ton but Rheem doesn't have a 3.5-ton and I don't want to mix-and-match. The specs for this Rheem combo look pretty good, probably due in part to the large supply duct size (21 inch) for the 3-ton coil.

    I can't post prices here but this can be done at a very reasonable price.

    Any thoughts or comments?

    RPNL is a good heat pump. We have quite a few out over the last couple of years.

    Good equipment but the RPNL does come in a 3.5 ton.

    No it's the RCFL coil that I would oversize to 3.5-ton if it was available.
