Practical Tips to Extend the Life of Your Home’s Furnace

Atlantic Refrigeration • July 7, 2025

The reliability and lifespan of your furnace depend on how well you take care of it. However, as a homeowner, you might not know for sure what steps to take to maintain it. Here are some of the best ways to ensure your furnace lasts for as long as possible.

Change the Filters

Every two to three months, change the filters in your furnace. Clean filters help it heat and blow out air more effectively. They also spare your heater from overworking, using too much energy and wearing out prematurely.

Keep the Vents and Register Clear

Inspect and clean the vents in your home regularly. Use a brush, broom or vacuum to remove dust, dirt and other debris. Make sure there are no objects, like furniture or boxes, in front of the vents and register.

Seal and Insulate the House

Take Care of the Blower Motor

Hire technicians to inspect and service your furnace’s blower motor at least once a year. This component has moving parts that need regular lubrication to prevent friction and wear. Servicing it annually also prevents the blower motor from accumulating and blowing out dust into your home.

Keep the Area Around the Furnace Clear

Your furnace will have to work harder, increasing the risk of premature wear, if you fail to keep the area around it clear. Avoid placing objects, like totes and boxes, around it that can impede airflow. Likewise, vacuum or sweep the area around it regularly to keep dust and lint away.

Monitor the Heat Exchanger

The heat exchanger in your furnace transfers heat from the combustion process to the air in your home. If it corrodes or has damage like cracks in it, it puts your heating system at risk of failure. A damaged heat exchanger can also put your home in danger of carbon monoxide poisoning.

Keep the Thermostat at a Steady Setting

Avoid changing the setting on your furnace’s thermostat repeatedly. Keep it at a steady temperature. Changing the setting frequently causes the heater to use more energy and cycle more often.

Schedule Professional Maintenance

At least once a year, schedule professional maintenance for your home’s furnace. Professional technicians will inspect it thoroughly. This service addresses minor issues before they become larger and pricier ones later. It also helps your heater last longer and work more efficiently.

In general, most furnaces and heat pumps will last 15 to 20 years.
