A frosty house is an unwelcome situation. The best thing to do when this happens is to check and assess your gas furnace before it fails. Do not wait when a problem comes up or when you have freezing indoor temperatures. It might be time to replace your gas furnace.
Checking Your Gas Furnace
- Know the Age of Your Unit. Your gas furnace may have been there before you moved in and as old as the house. Look for the manual or call the manufacturer by giving the furnace’s model number.
- Lifespan. The average lifespan of modern furnaces is 20 to 30 years. If the unit is more than 15 years old and not working properly, then consider replacing it.
- Energy Efficiency. Compared to an ordinary or traditional gas furnace, a new Energy Star-qualified gas furnace is usually 15% more efficient and is 4% more efficient than a standard model. This is according to the U.S. Energy Star program. The Environmental Protection Agency added that a new Energy Star gas furnace would save every homeowner an average of $91 in energy costs each year.

Know the AFUE Rating. AFUE (annual fuel utilization efficiency) is a rating to measures a furnace’s operating efficiency. An AFUE of below 8% means you need to replace your furnace with a more efficient unit. The new gas furnaces are commonly ranked by efficiency. The ultra-high-efficiency gas furnaces have up to 97% efficiency. These models have variable-speed controls and fans. The high-efficiency furnaces have a 90% efficiency while the mid-efficiency furnaces have an 80% efficiency.
