As the seasons change, the more you feel the cooler air gusting outside. And … inside your home? If your gas furnace is blowing cold air and giving a chill to your Los Angeles home, it’s time to contact AZ Air Conditioning and Heating. Sometimes a lack of warm air from your gas furnace results in a major repair, but often it can be an easy 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 regular maintenance completed on your gas furnace recently and you’ve neglected to replace your air filter, both could be the reason why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, 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 models, for a gust of air to extinguish a pilot light. Other factors when it comes to an extinguished pilot light are faulty 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 fight 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 could be losing a lot of heated air before it can get to the vents.
