Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system turn on and you’re anticipating a cozy blast of warm air, but instead all you have is cool air blowing. That’s not preferable in freezing temperatures!

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

 

  • Thermostat

 

It might seem silly, but the thermostat is the first place you should check. It’s the first place any heating system technician will check, too. Confirm 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 being released, thus blowing cold air. Turning it to “auto” will make sure the furnace only blows when it’s actually heating the air to keep your home warm and cozy.

 

  • Air Filter

 

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

 

  • Duct Work

 

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