Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system kick on and you’re ready for 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 couple reasons why your heating equipment could be blowing cold air. Service Experts Heating & Air Conditioning is here with a couple of them to help you find the culprit.

 

  • Thermostat

 

It could sound silly, but the thermostat is the first place you should check. It’s the first place any heating system technician will check, too. Verify the system is set to “auto and not “on.” If the thermostat is set to “on” then your furnace will blow constantly, even when it isn’t heating the air coming out, thus blasting cold air. Flipping 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

 

Most air filters need to be changed every month to prevent them from becoming dirty and clogged. If your filters aren’t swapped out often enough, the clogged air filter may restrict airflow into your heating equipment. If this happens, it can overheat your equipment, causing the furnace to stop heating as a safety precaution.

 

  • Duct Work

 

If your duct work has leaks, connection troubles, or was designed incorrectly, it could allow warm air from the heating equipment 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 heating system is heating non-living space, and will have to work overtime to keep your home warm.

 

There are multiple other reasons that your heating system could give off cold air.
