As the seasons change, the more you feel the cool air blowing outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your York home, it’s time to contact Strine's Heating & Air Conditioning. Sometimes a lack of warm air from your gas furnace means a major repair, but a lot of time 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 could be overheating
If you haven’t had regular maintenance done on your gas furnace for some time and you’ve forgotten to change your air filter, either could indicate why your furnace is blowing cool air. A dirty air filter can prevent air from flowing freely through your furnace. If that happens, the furnace might overheat and cause 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 credited 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 damaged gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can cause issues 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 leave you in the cold.
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 might be losing a lot of heated air before it ever reaches your vents.
