Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your heating system start up and you’re anticipating a cozy blast of warm air, but instead all you have is cool air blowing. That’s not what you want in the freezing weather!

There are a handful of reasons why your furnace could be giving off cold air. Service Experts Heating & Air Conditioning is here with a few of them to help you find the problem.

 

  • Thermostat

 

It could feel silly, but the thermostat is where you should start. It’s the starting place for any furnace technician, too. Confirm the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your furnace will blow continuously, even when it is not actually heating the air coming out, thus putting off cold air. Flipping 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

 

The majority of air filters need to be changed once a month to avoid them from becoming dirty and clogged. If air filters aren’t replaced often enough, the clogged air filter may impede airflow into your furnace. If this happens, it can overheat your system, causing the system to stop heating as a safety precaution.

 

  • Duct Work

 

If your duct work contains leaks, connection issues, or was not designed correctly, it could permit warm air from the heating system to leak out. This would not only cause your heating equipment to produce cold air, it could significantly run up your heating bills since your heating equipment is heating non-living space, and will have to work overtime to keep your home at the desired temperature.
