Why is My Furnace Blowing Cool?

Furnace Blowing Cool

Is your furnace blowing cool air into your Harvey, Louisiana, home? If you’re not getting the warmth that you need, it’s important to evaluate the problem as quickly as possible. Some faulty parts will only get worse if the issue isn’t addressed. Check for these common causes of cool air from your furnace.

The Filter Is Clogged

Check your filter first if you’re having trouble with your home comfort. A clogged filter makes it hard for the furnace to pull air through. This reduction in airflow will cause you to feel less warmth coming through your vents. You should change your filter every one to three months, or any time it’s visibly dirty.

The Thermostat Settings Are Wrong

Make sure your thermostat settings are correct if your heating system is blowing cool air. If the fan is set to “on” rather than “auto,” your heater will blow air continuously whether it’s actively warming that air or not. You will also experience cool airflow if your system was accidentally set to AC rather than heat. These accidents are especially common in homes with children.

If the settings are correct, you may have a more complex problem with the thermostat where it’s not communicating your settings properly to the furnace. This requires the assistance of a trained technician who can recalibrate your thermostat for you.

Problems With the Pilot Light

Check the pilot light for your furnace and make sure that it’s on. If the light is off, you can attempt to relight it yourself to get the heater up and running again. If you have trouble lighting it, however, you should call a professional. You might have a faulty thermocouple or electronic ignition, both of which require a knowledgeable repair person.

If these tips don’t help you get to the bottom of the problem, it’s time for you to call an experienced technician out to check your furnace. Call Caribbean Breeze Heating & Cooling for all your furnace repair needs.
