90%+ AFUE AC + Gas Furnace Systems

High-efficiency air conditioner + gas furnace systems with a 90%+ AFUE gas furnace. AFUE is the share of the fuel a furnace turns into heat for your home: a 90% or higher furnace wastes 10% or less, condenses its exhaust and vents through PVC pipe.

These systems make the most sense in colder climates and long heating seasons, where the fuel savings add up fastest, and they are often required by local code or rebate programs.

What you’ll find here

  • Brands: Goodman
  • Cooling efficiency: 13.4 to 19 SEER2
  • Furnace efficiency: 92%, 96% and 97% AFUE
  • Furnace configuration: upflow, downflow and horizontal
  • Also available with two-stage equipment
  • 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
  • Plan for a condensate drain and PVC venting if you are replacing an 80% furnace
  • Compare SEER2 for cooling efficiency; higher numbers lower summer bills
  • Size from a Manual J load calculation, not just square footage
  • Check the furnace cabinet width so the coil and plenum line up

What changes when you move to a 90%+ furnace?

A condensing furnace needs a condensate drain and PVC intake and exhaust piping, so plan for a drain line and a new vent route if you are replacing an 80% unit. In exchange you get lower gas bills and, in many areas, eligibility for utility rebates. Check local code: some regions now require high-efficiency furnaces in new installs.
