As the weather changes, the more you feel the colder air gusting outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Franklin & South Indy home, it’s time to call Winters Heating and Cooling. Once in a while an absence of warm air from your gas furnace means a big repair, but often it can be a small fix. Here are several reasons your gas furnace could be blowing cold air instead of keeping your home toasty.
Your furnace could be overheating
If you haven’t had regular maintenance performed 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 block 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’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 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 appropriately 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.
