As the seasons change, the more you feel the cool air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Dresden home, it’s time to reach out to McFadden Heating & Cooling. Occasionally a lack of warm air from your gas furnace calls for a big repair, but a lot of time it can be a small fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of making your home warm and cozy.
Your furnace may 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 cold air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace could 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 attributed 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 extinguish a pilot light. Other reasons for an extinguished pilot light are defective gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can mean 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 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.
