What is a 90% Furnace?

A 90% furnace has an Annual Fuel Utilization Efficiency of 90% or higher.

The most efficient gas furnace on the market is one that has an A.F.U.E. (Annual Fuel Utilization Efficiency) of 90% or higher. For every dollar spent on your heating bill, between 90-98 cents actually heats your home and only 8-2 cents are lost to your chimney. So a lower rated furnace heats your home less and loses more. We can talk to you about any other question you have about 90% furnaces or schedule an appointment to install one in your home.
