Top Reasons Your Furnace is Blowing Cold Air

Posted on

When the cold weather hits the DC area there’s nothing more satisfying than relaxing in a warm and cozy home. And there’s nothing worse than a working furnace that’s blowing cold air—leaving you chilly and your home uninviting. But there’s no need to worry! If your vents are blowing out air that is room temperature, we have a solution. The heating experts at Michael Bonsby Heating & Air Conditioning have come up with several simple ways for you to troubleshoot the problem yourself!

Stop Your Furnace from Blowing Cold Air

One of the only ways to address furnace problems before they cause unrepairable damage is through proper annual HVAC maintenance. But if your furnace is running and the air coming out of the vents is cold—give the following tips a try!

  • Is your thermostat set to ON? Or is your thermostat set to AUTO? Many homeowners think that your heating system should be set to ON—when in reality, this means that the fan on the furnace is continually blowing air through the homes’ ventilation system even when the furnace is not actually heating the air.
  • Have you checked your air filter lately? A dirty air filter restricts the airflow into your furnace, which can result in an overheated furnace. If your furnace becomes overheated, a safety control will shut off the burners—stopping the furnace from heating the air.
  • Is your pilot light out? If the pilot light is out, there could be a problem with the ignition system, which means the furnace isn’t lighting the fuel. Try relighting the furnace pilot light, if it stays on it was a simple fix! If it doesn’t stay on, it could be a bigger issue that needs to be addressed by a professional.
