How Often Should You Service Your Furnace?

January 7, 2026

This is one of the most common questions we hear from homeowners, especially once the weather starts getting cold. The short answer is once a year, but there’s more to it than just checking a box.

Once a Year Is Usually Enough


For most homes, having your furnace serviced once a year is all it really needs. The best time to do it is in the fall, before you actually rely on it every day. Annual maintenance helps catch small issues early, before they turn into a no-heat call in the middle of winter.


During a normal furnace service, a technician will usually:

  • Check that the burners are firing correctly
  • Inspect safety switches and controls
  • Look over electrical connections
  • Check airflow and temperatures
  • Inspect the heat exchanger for visible issues
  • Make sure everything is running the way it should


It’s not about selling repairs. It’s about making sure the system is safe and reliable.



What Happens If You Skip Furnace Maintenance?


A lot of people skip maintenance because the furnace seems “fine.” And sometimes it is. But when problems do happen, they usually come from lack of maintenance.


Skipping service can lead to:

  • Higher energy bills
  • More wear on parts
  • Shorter system lifespan
  • Breakdowns when you need heat the most


Most emergency furnace repairs we see didn’t come out of nowhere. They built up over time.



Older Furnaces Need a Little More Attention


If your furnace is over 10 or 15 years old, yearly maintenance becomes even more important. Older systems are more likely to have worn parts, airflow issues, or safety concerns that aren’t obvious until someone looks closely.


Regular inspections can help you plan ahead instead of being forced into a rushed decision during a breakdown.



What You Can Do Yourself


There are a few simple things homeowners can handle:

  • Change the air filter regularly
  • Keep vents and returns clear
  • Pay attention to new noises or smells


Anything involving gas, electrical components, or internal safety controls should always be left to a professional.
