Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system turn on and you’re ready for a cozy blast of warm air, but instead all you have is cool air blowing. That’s not what you want in freezing temperatures!

There are a couple reasons why your heating system could be putting off cold air. Strand Brothers Service Experts is here with a few of them to help you detect the problem.

 

  • Thermostat

 

It could feel silly, but the thermostat is the first place you should check. It’s the starting point for any heating technician, too. Verify the system is set to “auto and not “on.” If the thermostat is set to “on” then your furnace will blow constantly, even when it isn’t really heating the air being produced, thus blowing cold air. Turning it to “auto” will make sure the furnace only blows when it’s truly heating the air to keep your home warm and comfy.

 

  • Air Filter

 

The majority of air filters need to be changed monthly to keep them from growing dirty and clogged. If your filters aren’t changed often enough, the clogged air filter may impede airflow into your heating system. If this occurs, it can overheat your furnace, causing the furnace to stop heating as a safety measure.

 

  • Duct Work

 

If your duct work has leaks, connection problems, or was not designed correctly, it could let warm air from the heating system to escape out. This would not only cause your heating system to produce cold air, it could actually run up your heating bills since your furnace is heating non-living space, and will have to work overtime to keep your home warm.

 

There are several other reasons that your furnace could produce cold air.
