Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system kick on and you’re ready for a cozy blast of warm air, but instead all you feel is cool air blowing. That’s not what you want in the freezing weather!

There are a couple reasons why your heating system could be putting off cold air. Wesley Wood Service Experts Heating & Air Conditioning is here with a few of them to help you locate the problem.

 

  • Thermostat

 

It might feel silly, but the thermostat is the first place you should check. It’s the starting point for any heating technician, too. Make sure the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your heating system will blow continually, even when it is not actually heating the air coming out, thus blowing cold air. Turning it to “auto” will make sure the heating equipment only blows when it’s really heating the air to keep your home warm and comfy.

 

  • Air Filter

 

Most air filters need to be changed monthly to keep them from growing dirty and clogged. If your filters aren’t replaced often enough, the soiled air filter may restrict airflow into your heating equipment. If this takes place, it can overheat your system, 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 furnace to blow cold air, it could actually run up your heating bills since your furnace is heating non-living space, and will have to work more to keep your home warm.

 

There are several other reasons that your heating equipment could blow cold air.
