Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the weather changes, the more you feel the cool air blustering outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Chatsworth home, it’s time to call True Temp Heating & Air Inc. Sometimes an absence of warm air from your gas furnace calls for a big repair, but often it can be a simple 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 completed on your gas furnace for some time and you’ve overlooked changing 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. When this happens, the furnace might 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 related to something as simple as a pilot light that’s gone out. It’s possible, particularly with older furnaces, for a gust of air to extinguish 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 cause challenges 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 fight to stay lit and not be able to bring warmth to your home.

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 even reaches the vents throughout the home.
