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 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. Service Experts Heating & Air Conditioning is here with a few of them to help you locate the problem.

 

  • Thermostat

 

It may seem silly, but the thermostat is the first place you should check. It’s the starting place for any furnace technician, too. Confirm the system is set to “auto and not “on.” If the thermostat is set to “on” then your heating system will blow constantly, even when it isn’t heating the air being produced, thus putting off cold air. Turning it to “auto” will make sure the heating equipment only blows when it’s really heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

Most air filters need to be changed once a month to keep them from getting dirty and clogged. If air filters aren’t replaced often enough, the clogged air filter may obstruct airflow into your heating equipment. 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 troubles, or was not designed correctly, it could let warm air from the furnace to seep out. This would not only cause your furnace to blow cold air, it could significantly run up your energy bills since your heating system is heating non-living space, and will have to work more to keep your home warm.
