Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the cooler air gusting outside. And … inside your home? If your gas furnace is blowing cold air and putting a chill to your Liberty home, it’s time to call Air Unlimited Heating & Cooling. Occasionally the loss of warm air from your gas furnace results in a big repair, but many times it can be an easy fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of making your home warm and cozy.

Your furnace may be overheating

If you haven’t had routine maintenance done on your gas furnace recently and you’ve neglected to replace your air filter, both could be the reason why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace may overheat and shut down its burner.

Your pilot light may have gone out

It could be that a lack of warm air from your gas furnace can be credited to something as simple as a pilot light that’s gone out. It’s possible, specifically with older systems, for a draft to smother a pilot light. Other factors when it comes to an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can result in problems for your gas furnace, so can other furnace components if they aren’t properly cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle to stay lit and not be able to bring warmth to your home.

Your ducts may not be properly sealed

If your ducts aren’t sealed properly or if they have any cracks or holes in them, you could be losing a lot of heated air before it can get to the vents.
