Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cooler air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Derby home, it’s time to call Giordanos Heating and Air Conditioning. Sometimes a lack of warm air from your gas furnace means a big repair, but often it can be an easy fix. Here are several reasons your gas furnace may be blowing cold air instead of making your home warm and cozy.

Your furnace might be overheating

If you haven’t had routine maintenance done on your gas furnace lately and you’ve overlooked changing your air filter, each could be the reason why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace might overheat and shut down its burner.

Your pilot light may have gone out

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

Your furnace is dirty

Just as a dirty air filter can result in challenges for your gas furnace, so can other furnace components if they aren’t correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to fight to stay lit and leave you in the cold.

Your ducts may not be properly sealed

When ducts are correctly sealed or if they have any cracks or holes in them, you may be losing a lot of heated air before it even reaches the vents throughout the home.
