As the temps change, the more you feel the cool air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your Cambridge home, it’s time to contact Pliescott HVAC Services LLC . Sometimes an absence of warm air from your gas furnace means a big repair, but many times it can be an easy fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of warming up your house.
Your furnace might be overheating
If you haven’t had routine maintenance done on your gas furnace recently and you’ve overlooked changing your air filter, either 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 might overheat and shut down its burner.
Your pilot light may have gone out
It could be that 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 models, for a breeze to put out a pilot light. Other causes of an extinguished pilot light are faulty gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can result in issues 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 battle to stay lit and not be able to bring warmth to your home.
Your ducts may not be properly sealed
When ducts are correctly sealed or if they have any cracks or holes in them, you could be losing a lot of heated air before it even reaches the vents throughout the home.
