Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your furnace turn on and you’re anticipating a cozy blast of warm air, but instead all you feel 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. TML Service Experts is here with a few of them to help you detect the issue.

 

  • Thermostat

 

It might seem silly, but the thermostat is the first thing you want to look at. It’s the starting point for any heating technician, too. Make sure the system is set to “auto and not “on.” If the thermostat is set to “on” then your HVAC system will blow continually, even when it isn’t really heating the air being released, thus blasting cold air. Flipping it to “auto” will make sure the heating equipment only blows when it’s actually 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 getting dirty and clogged. If they aren’t swapped out often enough, the soiled air filter may restrict airflow into your heating equipment. If this occurs, it can overheat your furnace, causing the furnace to stop heating as a safety precaution.

 

  • Duct Work

 

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