As the temps change, the more you feel the cool air blustering outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Crystal and Twin Cities home, it’s time to call GV Heating & Air. Sometimes an absence of warm air from your gas furnace calls for a large repair, but often it can be a small fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of warming up your house.
Your furnace might be overheating
If you haven’t had routine maintenance done on your gas furnace lately and you’ve neglected to replace your air filter, each could indicate why your furnace is blowing colder air. A dirty air filter can prevent air from flowing freely through your furnace. If that happens, the furnace might overheat and shut down its burner.
Your pilot light may have gone out
It could be that 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, especially with older systems, for a gust of air to put out a pilot light. Other causes of an extinguished pilot light are defective 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 properly 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
If your ducts aren’t sealed properly or if they have any cracks or holes in them, you could be losing a lot of heated air before it ever reaches your vents.
