Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your HVAC system kick on and you’re anticipating a cozy blast of warm air, but instead all you get is cool air blowing. That’s no good in the freezing weather!

There are a few reasons why your furnace could be putting off cold air. Midland Air Service Experts is here with a few of them to help you detect the culprit.

 

  • Thermostat

 

It might seem silly, but the thermostat is the first place you should check. It’s the starting place for any furnace technician, too. Verify the system is set to “auto and not “on.” If the thermostat is set to “on” then your heating system will blow continuously, even when it is not actually heating the air coming out, thus blasting cold air. Changing it to “auto” will make sure the heating equipment only blows when it’s truly heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

Typically air filters need to be changed once a month to avoid them from becoming dirty and clogged. If your filters aren’t swapped out often enough, the dirty air filter may obstruct airflow into your heating system. If this takes place, it can overheat your system, causing the equipment to stop heating as a safety precaution.

 

  • Duct Work

 

If your duct work has leaks, connection troubles, or was not designed properly, it could permit warm air from the furnace to seep out. This would not only cause your heating equipment to blow cold air, it could seriously run up your heating bills since your furnace is heating non-living space, and will have to work more to keep your home at the desired temperature.
