Reasons for Your Furnace Blowing Cold Air in Hebron, KY

January 31, 2025

There is nothing more frustrating than dealing with a furnace that blows cold air during the winter in Hebron, KY. Let’s explore four possible reasons this would happen with your furnace.

1. Clogged or Dirty Air Filter

A clean air filter is vital to ensure your furnace runs efficiently. A dirty air filter will prevent incoming air from entering your system. This will cause longer heating cycles where your system will blow cold air before it can heat it to the appropriate temperature.

2. Leaky Air Ducts

Holes or cracks in your ductwork can allow cold air to enter your HVAC system. While your furnace still can operate correctly when there are leaks, the cold air that enters your air ducts can give the appearance that it’s blowing out cold air.

3. Damaged Pilot Light

If you have a gas furnace and experience cold air coming out of your vents, check to make sure the pilot light is on. The pilot light ignites the burners and adequately heats the air before pushing it throughout your home. Proper maintenance is the best way to make sure all of your systems’s components work correctly all year long.

4. Incorrect Thermostat Settings

When running your furnace in the winter, you should make sure to set your thermostat to Auto mode instead of On. When using the On setting, your furnace’s fan will run continuously throughout the day even when it’s not producing hot air. This will give the appearance that your furnace is blowing out cold air when it’s just the fan circulating air.

Whenever you notice your furnace blowing cold air, it’s important that you quickly address the issue to prevent a larger problem from occurring. Contact our friendly team at Western Hills Heating and Air Conditioning today for efficient heating repair services.
