Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your heating system start up and you’re anticipating a comfortable blast of warm air, but instead all you get is cool air blowing. That’s no good in the freezing weather!

There are a couple reasons why your heating equipment could be blowing cold air. Aramendia Plumbing, Heating and Air is here with some of them to help you find the problem.

 

  • Thermostat

 

It might sound 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 continuously, even when it is not actually heating the air being released, thus putting off cold air. Flipping it to “auto” will make sure the furnace only blows when it’s really heating the air to keep your home warm and cozy.

 

  • Air Filter

 

Most air filters need to be changed once a month to avoid them from getting dirty and clogged. If they 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 furnace, causing the equipment to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work has leaks, connection problems, or was not designed properly, it could let warm air from the heating equipment to escape out. This would not only cause your furnace to produce cold air, it could seriously 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.
