As the temps change, the more you feel the cool air blustering outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Wyandotte home, it’s time to contact Gee & Missler Heating & Air Conditioning. Occasionally an absence of warm air from your gas furnace calls for a large repair, but a lot of time it can be an easy fix. Here are some of the main reasons your gas furnace might be blowing cold air instead of warming up your house.
Your furnace could be overheating
If you haven’t had ongoing maintenance performed on your gas furnace for some time and you’ve neglected to replace your air filter, either could indicate why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. If that happens, 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, particularly with older furnaces, for a breeze to smother a pilot light. Other reasons for an extinguished pilot light are damaged 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 correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle to stay lit and leave you in the cold.
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.
