Gas Furnace

Gas furnaces are one of the most commonly used home heating systems in the United States. Furnaces push warmed air through duct work and vents throughout the house. It is possible for a furnace to heat a space without duct work, however many homeowners purchase central heating and air units that are larger and often at the center of a heating system.

Average Gas Furnace Prices

Ever wonder how much a gas furnace costs? The price and efficiency of your new furnace will vary from brand to brand, so it is highly important to get multiple estimates from local heating contractors. Gas furnace prices are said to be more affordable than oil furnaces or electric heating.

Small gas furnace units cost between $800 -$1,600. Expect to pay an extra $1,000 -$2,000 for furnace installation.
Replacing a gas furnace with existing duct work costs $1,500 -$4,500. Older systems can be unpredictable however, and may run $6,000 -$7,500 if extensive work is needed to install your new furnace.
New installation of a high efficiency gas furnace runs an average cost of $2,600 -$5,750 for most brands. If there is repair work needed to your existing duct work, you can expect a price of $6,000 -$10,000.

Gas Furnace Efficiency Ratings

The effectiveness of a gas furnace is based on AFUE (Annualized Fuel Utilization Efficiency) measurement. So what exactly is AFUE?

“Essentially the AFUE number is a percentage which relates to the amount of energy that is used to heat your home. In other words – how much heat do you get to enjoy versus heat that escapes out of a chimney or vent pipe.” - Home Improvement Helper

A 15 year old furnace typically loses about half the heat it puts out, giving it an AFUE rating of 50-60%. A modern gas furnace can range as high as 97% AFUE.
