Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system turn on and you’re expecting a cozy blast of warm air, but instead all you feel is cool air blowing. That’s not what you want in the freezing weather!

There are a couple reasons why your furnace could be blowing cold air. Service Experts Heating & Air Conditioning is here with some of them to help you locate the culprit.

 

  • Thermostat

 

It might feel silly, but the thermostat is where you should start. 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 isn’t heating the air being released, thus blasting cold air. Changing it to “auto” will make sure the heating system 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 monthly to avoid them from growing dirty and clogged. If your filters aren’t changed often enough, the clogged air filter may impede airflow into your furnace. If this happens, it can overheat your system, causing the furnace to stop heating as a safety measure.

 

  • Duct Work

 

If your duct work has leaks, connection issues, or was designed incorrectly, it could allow warm air from the heating system to escape out. This would not only cause your heating system to produce cold air, it could significantly 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.

 

There are multiple other reasons that your heating equipment could produce cold air.
