Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system start up and you’re anticipating a comfy blast of warm air, but instead all you have is cool air blowing. That’s not preferable when it’s cold outside!

There are a handful of reasons why your furnace could be putting off cold air. D.A. Bennett Service Experts is here with some of them to help you locate the problem.

 

  • Thermostat

 

It might feel silly, but the thermostat is where you should start. It’s the starting point for any heating technician, too. Verify 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 is not actually heating the air coming out, thus blasting cold air. Turning it to “auto” will make sure the furnace only blows when it’s truly heating the air to keep your home warm and cozy.

 

  • Air Filter

 

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

 

  • Duct Work

 

If your duct work contains leaks, connection problems, or was designed incorrectly, it could let warm air from the heating equipment to seep out. This would not only cause your heating equipment to give off cold air, it could seriously run up your energy bills since your heating equipment is heating non-living space, and will have to work overtime to keep your home at the desired temperature.
