Gas Furnaces

Deciding whether to repair or replace your gas furnace is a difficult issue. Furnaces are rated by the Annual Fuel Utilization Efficiency ratio (AFUE), which is the percent of heat produced for every dollar of fuel consumed. Like the miles per gallon on your car, the higher the AFUE rating, the lower your fuel costs. All furnaces manufactured must meet at least 78% AFUE. If your furnace is 10 to 15 years old, it probably falls well below the current furnace minimum and wastes energy.

An older gas furnace could waste up to 45% of the heat it generates. But today's furnaces can operate at as much as 97% AFUE, which means instant cost savings in operation.

Other important factors to consider when replacing your furnace include:

  •  How long you plan to live in your house
  •  Special comfort needs
  •  Fuel availability
  •  Fuel cost
  •  Geographic area and climate

All these factors, plus your lifestyle and family needs, add up to show you which system is best for you.

There are many options for replacing your gas furnace. We recommend Lennox, Trane, Maytag and Carrier -- the top brand names with finest manufactured and most efficient systems in the industry. Most of our new systems have received the Energy Star rating for high efficiency.
