What To Do If My Heater Keeps Running

December 30, 2019

There are several explanations for a heater that keeps running for too long. It could signal that it’s time for a tune-up. There could also be a malfunction outside of your heating system causing the problem. Here are some common reasons for heaters running too much.

Your Thermostat Isn’t Set Correctly

Since this is a simple problem, it’s the first one to address. Your spouse or someone else might’ve cranked up the heat to 80 degrees, which can result in your heater constantly running. Check also that the thermostat is set to “heat” and that the fan is on the “auto” setting.

Inspect Your Air Filter

A clogged, dirty air filter can cause your heating system to work overtime. It’s not able to send enough heat into your home, so it just keeps running. The air filter should be cleaned and replaced every two to three months.

Head to Your Attic to Check Your Ductwork

Your ductwork may be leaking. This means that some of the heat is ending up in your attic instead of your house, causing the heating system to keep going. Carefully walk only on the joists and look at the ductwork. While the heater is operating, search for leaks and seal them with HVAC tape.

It Might Be the Fan, Not the Heater

It might be that it only sounds like your heating system is constantly operating. If you have your thermostat fan setting set to “on,” this makes the heater blower motor run constantly. Set it to “auto” so that the motor only operates when the heating system is functioning.
