As the weather changes, the more you feel the cool air blowing outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your the Rio Grande Valley home, it’s time to call Cytech Heating & Cooling L.C.. Occasionally the loss of warm air from your gas furnace calls for a major repair, but often it can be a simple fix. Here are a few of the more common reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.
Your furnace may be overheating
If you haven’t had routine maintenance completed on your gas furnace recently and you’ve neglected to replace your air filter, both could indicate why your furnace is blowing cool air. A dirty air filter can prevent air from flowing freely through your furnace. If this occurs, the furnace might overheat and cause the burner to shut down.
Your pilot light may have gone out
Sometimes 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 systems, for a gust of air to smother a pilot light. Other reasons for an extinguished pilot light are damaged gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can cause 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 battle to stay lit and leave you in the cold.
Your ducts may not be properly sealed
If your ducts aren’t properly sealed or if they have any cracks or holes in them, you may be losing a lot of heated air before it ever reaches your vents.
