The weather is changing in Madera, CA, which means now is the time to make sure your furnace is ready for the upcoming cold winter months of the year. If your furnace is old, you might be wondering how much longer it will last. Learn about the lifespan of a furnace and what you should do if your furnace has reached its life expectancy.

Life Expectancy of Electric Furnaces

An electric furnace usually lasts for 20 to 30 years. They are quick to install, and they have low maintenance needs. Because nothing is burned, there’s no need for a flue. The interior parts don’t get as dirty because no fuel is used. The parts most likely to fail are the capacitor and blower motor.

Typical Lifespan of a Gas Furnace

A gas furnace has a lifespan of 15 to 20 years. They require regular maintenance in order to safely burn gas. The combustion process creates toxic byproducts, and regular maintenance is critical for safety. The combustion of gas creates ash and other particles that can get into the inner workings, and those layers may cause problems for sensors, relays, blower belts and other components.

How to Help Your Furnace Reach Its Full Lifespan

Keeping up with regular tune-ups is the best way to help gas or electric furnace to reach its full lifespan. We recommend an autumn tune-up. Between professional maintenance visits, you should check the air filter. Do this each month. When it’s visibly dirty, replace it. Don’t wait longer than three months between air filter replacements. Maintain at least six feet of clearance around the furnace and your home’s air ducts and vents.
