Overheating is a common cause of furnace repair issues. You may smell a burning odor, hear unusual noises (like a loud, continuous hum), or experience frequent cycling, which occurs when the furnace turns on and off repeatedly without adequately heating the home. Here’s what you should know about the causes of and solutions to an overheating furnace.

What Causes an Overheating Furnace?

Poor airflow is a common reason for an overheating furnace. Air circulating through the system wicks heat away from the moving parts. When air can’t pass freely through the system, the components may overheat.

Dirty and worn parts can also cause overheating. Dust, debris, and faults in the moving components can result in friction that raises the system's internal temperature.

This often worsens as equipment ages, starts deteriorating, and accumulates grime. It's more likely to occur with furnaces that are at or near their expected life span of about 20 years.

How Can You Avoid an Overheating Furnace?

The most effective way to prevent overheating is to change the furnace filter regularly. The filter cleans the air before it enters the HVAC system. When it is dirty or clogged, it blocks airflow and allows heat to accumulate.

Change the filter ever 60 to 90 days or more frequently if your household contains pets or smokers. Ensure your duct vents aren't blocked so that air can circulate freely.
