efficiency chart

An American Standard gas furnace burns fuel and distributes it throughout the house.

  • Lower unit cost than heat pumps, but you’ll have to pair with an air conditioner.
  • Less efficient than heat pumps but upgrading to an energy efficient model can lower your energy bills.
  • Runs less often and has fewer moving parts so it will last longer
  • Warm and cozy hot air you can feel.

A super-efficient and quiet ductless system makes a lot of sense for condos and smaller homes, as well as for places in larger houses like additions, sun rooms, finished attics or garages.
