Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your HVAC system kick on and you’re expecting a comfy 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 system could be putting off cold air. Service Experts Heating & Air Conditioning is here with a few of them to help you locate the culprit.

 

  • Thermostat

 

It might feel silly, but the thermostat is the first place you should check. It’s the first place any heating system technician will check, too. Make sure 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 is not actually heating the air being released, thus blasting cold air. Changing it to “auto” will make sure the furnace only blows when it’s actually heating the air to keep your home warm and comfy.

 

  • Air Filter

 

Typically air filters need to be changed every month to avoid them from growing dirty and clogged. If your filters aren’t replaced often enough, the clogged air filter may impede airflow into your heating equipment. If this occurs, it can overheat your system, causing the system to stop heating as a safety measure.

 

  • Duct Work

 

If your duct work contains leaks, connection issues, or was designed incorrectly, it could permit warm air from the furnace to escape out. This would not only cause your heating system to blow cold air, it could actually run up your heating bills since your heating system is heating non-living space, and will have to work overtime to keep your home warm.
