Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the colder air gusting outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Kingsville home, it’s time to reach out to Four Seasons Air Conditioning and Heating LLC. Occasionally the loss of warm air from your gas furnace means a big repair, but often it can be a small fix. Here are some of the main reasons your gas furnace might be blowing cold air instead of keeping your home toasty.

Your furnace may be overheating

If you haven’t had ongoing maintenance performed 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. When this happens, the furnace may overheat and force the burner to shut down.

Your pilot light may have gone out

It’s probable 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 furnaces, for a breeze to extinguish a pilot light. Other reasons for an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause problems for your gas furnace, so can other furnace components if they aren’t appropriately cleaned. A dirty gas burner or flame sensor could cause your furnace to battle 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 could be losing a lot of heated air before it can get to the vents.
