Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the colder air gusting outside. And … inside your home? If your gas furnace is blowing cold air and putting a chill to your Edinburg home, it’s time to contact Cytech Heating & Cooling. Sometimes a lack of warm air from your gas furnace calls for a major repair, but a lot of time it can be a small fix. Here are several reasons your gas furnace may be blowing cold air instead of keeping your home toasty.

Your furnace might be overheating

If you haven’t had regular maintenance done on your gas furnace for some time and you’ve neglected to replace your air filter, either 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 that happens, the furnace could overheat and cause the burner to shut down.

Your pilot light may have gone out

It could be that a lack of warm air from your gas furnace can be attributed to something as simple as a pilot light that’s gone out. It’s possible, specifically with older models, for a breeze 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 struggle to stay lit and reduce the warmth inside your house.

Your ducts may not be properly sealed

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