Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your heating system kick on and you’re ready for a cozy blast of warm air, but instead all you feel is cool air blowing. That’s no good in the freezing weather!

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

 

  • Thermostat

 

It could sound silly, but the thermostat is the first thing you want to look at. It’s the starting place for any furnace technician, too. Verify 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 isn’t really heating the air coming out, thus blasting cold air. Changing it to “auto” will make sure the furnace only blows when it’s truly heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

Most air filters need to be changed monthly to keep them from growing dirty and clogged. If they aren’t swapped out often enough, the dirty air filter may restrict airflow into your furnace. If this takes place, it can overheat your furnace, causing the furnace to stop heating as a safeguard.

 

  • Duct Work

 

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