As the weather changes, the more you feel the colder air blowing outside. And … inside your home? If your gas furnace is blowing cold air and putting a chill to your Franklin Lakes home, it’s time to reach out to Total Comfort. Occasionally a lack of warm air from your gas furnace means a big 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 could be overheating
If you haven’t had routine maintenance performed on your gas furnace lately and you’ve overlooked changing your air filter, each could signal why your furnace is blowing cool air. A dirty air filter can block 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 related to something as simple as a pilot light that’s gone out. It’s possible, especially with older furnaces, for a gust of air to extinguish 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 appropriately cleaned. A dirty gas burner or flame sensor could cause your furnace to fight to stay lit and reduce the warmth inside your house.
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 may be losing a lot of heated air before it ever reaches your vents.
