Where the GZV7SA2410 dual fuel system fits

Dual fuel is the right choice when you already have gas at the house and you want the cheaper of the two heat sources running at any given outdoor temperature. The ComfortNet thermostat watches the outdoor temperature and hands heating between the heat pump and the furnace at the balance point, so you get heat-pump efficiency through the mild part of the season and full gas heat when it turns genuinely cold. At 2 tons and 23,200 BTU of cooling this is a system for roughly 900 to 1,200 square feet, but a load calculation on your actual house is what should set the size, not a rule of thumb.

Everything in the box is factory-matched: the GZV7SA2410 variable-capacity heat pump, the GRVT800603BN 80% AFUE two-stage gas furnace, the CAPEA3026B3 upflow coil and the GTST-CW-WH-A WiFi thermostat. Note the coil orientation — this is the upflow configuration, for a furnace standing upright with the coil on top. If your furnace lies on its side in an attic or crawlspace you want the horizontal-coil version of this same system instead. An 80% AFUE furnace also vents through a metal flue rather than PVC, so it is the simpler swap when you are replacing an existing 80% unit.

Browse the rest of the range in Goodman dual fuel systems, or work out the size first with our HVAC sizing tool. This is a licensed-installer system — gas, refrigerant and venting all have to be done to code — and if you want us to sanity-check the model numbers or the orientation before you spend the money, call (877) 843-4822.
