AC + Gas Furnace Systems by Furnace Efficiency (AFUE)

Shop air conditioner + gas furnace systems by the efficiency of the gas furnace. AFUE (Annual Fuel Utilization Efficiency) is the share of the fuel a furnace turns into heat for your home.

Choose your efficiency

  • 80% AFUE: lower upfront cost and simple metal-flue venting, a good fit for warmer climates with short heating seasons
  • 90%+ AFUE: condensing furnaces that waste 10% or less of their fuel, vent through PVC and save the most in colder climates

Every system is sold as an AHRI-matched set. Not sure which you need? Call 1.888.509.3391 and we will help you match your home.
