Gas Furnace FAQS


How long does a gas furnace last?

The life span of a gas furnace typically ranges between 15 to 20 years, although some can last even longer with proper maintenance and care. The longevity of your furnace can be influenced by several factors, including the quality of the installation, the brand and model of the furnace, how well it’s maintained, and the frequency and intensity of its use. Regular maintenance and timely repairs are crucial to maximizing the lifespan of your gas furnace.


How often does a gas furnace need professional service and maintenance?

It’s generally recommended that a gas furnace receive professional service and maintenance at least once a year. This typically involves a thorough inspection and cleaning of the furnace’s components, including the burner, heat exchanger, and blower motor. Regular maintenance helps ensure efficient operation, identifies potential issues before they become major problems, and extends the life of the furnace. The best time to schedule this service is in the early fall before the heating season begins.


What is AFUE?

AFUE stands for Annual Fuel Utilization Efficiency. It’s a measure of how efficiently a furnace or boiler converts the energy in its fuel to heat over the course of a typical year. Expressed as a percentage, a higher AFUE rating means higher efficiency. For example, a furnace with an AFUE of 90% converts 90% of the fuel to heat, with the remaining 10% lost in the conversion process. When shopping for a new furnace, looking at the AFUE rating can help you understand its efficiency and potential heating costs. In the United States, the Department of Energy mandates certain minimum AFUE ratings for new furnaces to ensure baseline efficiency and energy savings.
