A gas furnace is a heating system that uses a gaseous product as fuel to generate heat. The gaseous product that the furnace uses will vary depending on where you live. Typical choices are natural gas and propane.
Gas furnaces use a heat exchanger to warm the room air. The heat exchanger is a metal box. Inside the metal box of a gas furnace is a pilot light connected to the fuel source. The pilot light is also connected to a thermostat. This enables the homeowner to adjust the heat that the gas furnace produces without actually visiting the furnace.
Designed to deliver reliable and economical warmth, furnaces have efficiency ratings from 80% all the way up to 95% AFUE (Annual Fuel Utilization Efficiency is a measurement used to rate furnace efficiencies by dividing the ratio of heat output by heat input). And many are ENERGY STAR® qualified, which means they can significantly lower your utility bills, compared to conventional models. For optimal comfort and efficiency, a gas furnace can be combined with an electric heat pump in one dual-fuel system.
Possible Tax Credit - As part of the Energy Policy Act of 2005, the U.S. government has made a provision for tax credits of up to $200 for homeowners who install furnaces with an efficiency of 95% or greater. Consumers should discuss these tax credits with a tax professional to see if they qualify.
