Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your furnace turn on and you’re anticipating a comfortable 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 furnace could be giving off cold air. Comfortech Service Experts is here with a few of them to help you detect the problem.

 

  • Thermostat

 

It may seem silly, but the thermostat is where you should start. It’s the first place any heating system technician will check, too. Confirm the system is set to “auto instead of “on.” If the thermostat is set to “on” then your HVAC system will blow constantly, even when it is not actually heating the air coming out, thus blasting cold air. Turning it to “auto” will make sure the furnace only blows when it’s really heating the air to keep your home warm and cozy.

 

  • Air Filter

 

The majority of air filters need to be changed once a month to avoid them from getting dirty and clogged. If your filters aren’t changed often enough, the clogged air filter may restrict airflow into your furnace. If this occurs, it can overheat your furnace, causing the furnace to stop heating as a safeguard.

 

  • Duct Work

 

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