Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system start up and you’re expecting 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 putting off cold air. Service Experts Heating & Air Conditioning is here with a couple of them to help you detect the problem.

 

  • Thermostat

 

It might sound silly, but the thermostat is the first thing you want to look at. 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 constantly, even when it isn’t really heating the air being produced, thus blowing cold air. Changing 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 avoid them from becoming dirty and clogged. If they aren’t swapped out often enough, the soiled air filter may obstruct airflow into your furnace. If this happens, it can overheat your furnace, causing the equipment to stop heating as a safeguard.

 

  • Duct Work

 

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