Why Does My Heater Keep Running?

It’s a common concern during the colder months your heater runs constantly, and you’re left wondering if something’s wrong. Not only can this drive up your energy bills, but it can also be a sign that your HVAC system needs attention. At Parker’s Heating and Air Conditioning, we specialize in professional heating services, helping homeowners uncover the cause and offer effective, affordable solutions.

Common Reasons Your Heater Won’t Turn Off

There are several reasons your heater constantly running might be more than just a cold-weather response:

1. Thermostat Issues

If your thermostat is malfunctioning or set incorrectly, it may tell your heater to keep running even after your home has reached the desired temperature. Double-check your settings, and if it’s an older model, consider upgrading to a smart thermostat for better efficiency.

2. Dirty Air Filter

A clogged air filter can restrict airflow, forcing your system to work harder and longer. Replacing your air filter regularly can prevent your heater fan from running continuously when it is not needed.

3. Leaky Ductwork

When heated air escapes through duct leaks, your system has to compensate by running longer to maintain the set temperature. Parker’s offers duct inspection and sealing services to address this hidden issue.

4. Blower Fan Settings

If the heater fan keeps running, check your thermostat fan setting. If it’s set to “ON” instead of “AUTO,” the fan will blow air continuously, even when the heater isn’t actively warming the air.

5. Faulty Limit Switch

A malfunctioning limit switch can also cause the heater fan to run continuously, even after reaching the desired temperature. This requires a professional diagnosis and repair, which we’re happy to provide.

Why It Matters

A heater constantly running not only causes discomfort and noise, but it also leads to higher utility bills and potential wear on your system. Ignoring these signs can shorten your HVAC system’s lifespan and lead to costly breakdowns.
