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 Manassas home, it’s time to contact Woody's Sudden Service Inc. Occasionally a lack of warm air from your gas furnace results in a large repair, but a lot of time it can be an easy fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of keeping your home toasty.
Your furnace might be overheating
If you haven’t had regular maintenance performed on your gas furnace for some time and you’ve neglected to replace your air filter, either could indicate why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace could 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 credited to something as simple as a pilot light that’s gone out. It’s possible, particularly with older systems, for a breeze to extinguish a pilot light. Other factors when it comes to an extinguished pilot light are damaged 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 properly cleaned. A dirty gas burner or flame sensor could cause your furnace to battle 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 may be losing a lot of heated air before it can get to the vents.
