Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your HVAC system kick on and you’re anticipating a comfy blast of warm air, but instead all you get is cool air blowing. That’s no good when it’s cold outside!

There are a couple reasons why your heating equipment could be blowing cold air. Service Experts Heating & Air Conditioning is here with a couple of them to help you find the issue.

 

  • 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 instead of “on.” If the thermostat is set to “on” then your HVAC system will blow constantly, even when it isn’t heating the air being released, thus putting off cold air. Flipping it to “auto” will make sure the heating equipment only blows when it’s actually heating the air to keep your home warm and cozy.

 

  • Air Filter

 

Most air filters need to be changed once a month to keep them from getting dirty and clogged. If your filters aren’t swapped out often enough, the clogged air filter may obstruct airflow into your heating equipment. If this takes place, it can overheat your equipment, causing the system to stop heating as a safety measure.

 

  • Duct Work

 

If your duct work contains 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 furnace to blow cold air, it could seriously run up your heating bills since your heating system is heating non-living space, and will have to work overtime to keep your home at the desired temperature.
