Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the cool air gusting outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Marshalltown home, it’s time to contact Kapaun & Brown Inc.. Occasionally an absence of warm air from your gas furnace calls for a big repair, but a lot of time it can be a small fix. Here are several reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.

Your furnace might be overheating

If you haven’t had regular maintenance completed on your gas furnace for some time and you’ve overlooked changing your air filter, either could signal 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’s probable 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, especially with older models, for a breeze to extinguish 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 mean 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 battle 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.
