Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system kick on and you’re expecting a comfortable blast of warm air, but instead all you have is cool air blowing. That’s no good in freezing temperatures!

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

 

  • Thermostat

 

It may sound silly, but the thermostat is where you should start. 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 furnace will blow constantly, even when it isn’t really heating the air being released, thus putting off cold air. Flipping it to “auto” will make sure the heating system 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 monthly to keep them from becoming dirty and clogged. If they aren’t swapped out often enough, the soiled air filter may obstruct airflow into your furnace. If this happens, it can overheat your equipment, causing the system to stop heating as a safeguard.

 

  • Duct Work

 

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