Gas furnaces convert fuel into heat and use a blower to circulate warm air throughout your home. During the summer months your furnace shuts off its burners and works with your heat pump or AC to circulate cool air in your home. The more efficient your furnace is the less gas it will take to create heat all while saving you money on your gas and power bill.
When purchasing a gas furnace the AFUE (Annual Fuel Utilization Efficiency) is the standard for measuring the efficiency of a gas furnace. If you have a older furnace you may be spending more money on gas than you need to. Upgrading from a AFUE of 60 to 90 could save you up to $33.00 of every $100.00 spent in fuel. Most gas companies offer a rebate to their customers that have a high efficient gas furnace installed.
