5 Ton Dual Fuel Systems with a 100,000 BTU Furnace

A 5 Ton heat pump, a matched evaporator coil and a 100,000 BTU gas furnace, sold together as one AHRI-matched dual fuel system. In summer the heat pump cools like a central air conditioner. In winter it heats the home until the outdoor temperature drops to the switchover point, then the furnace takes over.

5 Ton systems typically suit homes of about 2,400 to 3,000 square feet. That is a balanced pairing for mixed climates, where the home needs real heating in winter and full cooling in summer.

What you’ll find here

  • Brands: Goodman
  • Cooling efficiency: 15.2 to 16 SEER2
  • Heat pump heating efficiency: 8.2 to 8.5 HSPF2
  • Furnace efficiency: 80%, 96% and 97% AFUE
  • Furnace configuration: upflow and downflow
  • Refrigerant: R-32
  • Every system is sold as an AHRI-matched set

How to choose

  • Confirm your furnace configuration (upflow, downflow or horizontal) matches your existing install
  • Choose 80% AFUE for mild winters and simple venting, 90%+ for cold climates and lower gas bills
  • Compare HSPF2 for heat pump heating efficiency and SEER2 for cooling
  • Size from a Manual J load calculation, not just square footage
  • Check the furnace cabinet width so the coil and plenum line up

Why pair a 5 Ton heat pump with a 100,000 BTU furnace?

Cooling capacity is set by the size of the home and its summer load. Heating capacity is set by winter. Pairing a 5 Ton heat pump with a 100,000 BTU furnace lets you size each side for its own job instead of compromising on one. The furnace and heat pump split the season roughly evenly in most mixed climates.
