Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system start up and you’re expecting a cozy blast of warm air, but instead all you get is cool air blowing. That’s no good when it’s cold outside!

There are a few reasons why your heating equipment could be putting off cold air. Midway Services is here with some of them to help you detect the culprit.

 

  • Thermostat

 

It could seem silly, but the thermostat is the first thing you want to look at. It’s the starting point for any heating technician, too. Confirm the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your HVAC system will blow continuously, even when it isn’t heating the air coming out, thus putting off cold air. Changing it to “auto” will make sure the heating system only blows when it’s really heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

The majority of air filters need to be changed every month to keep them from getting dirty and clogged. If your filters aren’t swapped out often enough, the soiled air filter may impede airflow into your heating equipment. If this happens, it can overheat your equipment, causing the furnace to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work includes leaks, connection issues, or was not designed correctly, it could let warm air from the furnace to escape out. This would not only cause your heating equipment to give off cold air, it could actually run up your energy bills since your furnace is heating non-living space, and will have to work harder to keep your home at the desired temperature.
