Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the cooler air gusting outside. And … inside 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 a lack of warm air from your gas furnace calls for a big repair, but many times 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 might be overheating

If you haven’t had routine maintenance done on your gas furnace for some time and you’ve forgotten to change your air filter, both 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 could 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, particularly with older systems, 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 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 battle to stay lit and reduce the warmth inside your house.

Your ducts may not be properly sealed

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