Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system start up and you’re expecting a comfortable blast of warm air, but instead all you feel is cool air blowing. That’s no good in the freezing weather!

There are a handful of 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 seem silly, but the thermostat is where you should start. It’s the starting point for any heating technician, too. Make sure the system is set to “auto instead of “on.” If the thermostat is set to “on” then your heating system will blow continuously, even when it isn’t heating the air being released, thus blowing cold air. Changing it to “auto” will make sure the furnace only blows when it’s truly heating the air to keep your home warm and cozy.

 

  • Air Filter

 

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

 

  • Duct Work

 

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