Is your furnace blowing cold air instead of warm air in your home? Though Theodore, AL, rarely dips below freezing, having a heater that’s out of order can still create an uncomfortable environment quite quickly. In this article, we discuss possible reasons your furnace might be blowing cold air and what you can do about it.

1. Clogged Filter

When your furnace struggles to get enough airflow, it can overheat and shut down, continuing to run the fan and push cold air to cool the system down. A leading cause of restricted airflow is a clogged and dirty furnace filter. Changing this may solve the problem and prevent future overheating errors from occurring.

2. Faulty Thermostat

Your thermostat is like the brain of your HVAC system. If a wire has a loose connection, it may mess up the entire temperature balance in your home. Alternatively, your thermostat may simply have the fan switched to ON instead of AUTO, causing it to run even when the heat isn’t.

3. Pilot Light Problems

It’s not an uncommon thing for a pilot light to go out. If it’s not on an automatic ignition system, you’ll need someone to come out and relight it for you. Our team would be happy to assist you with this problem, as well as fully inspect the system for other problems.

4. Damaged Ductwork

Holes in your ductwork cause a lack of proper airflow and circulation. Cold air from the attic may even leak into your home, causing cool air to blow out of the vents instead of warm air. Having experts properly check and seal your ducts will solve this problem.

5. Lack of Fuel

If the gas supply to your home is off, there will be nothing to ignite your furnace and heat your home with. Our team can help solve this problem and restore gas to your property.
