Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your furnace turn on and you’re ready for a comfortable blast of warm air, but instead all you have is cool air blowing. That’s no good in freezing temperatures!

There are a few reasons why your furnace could be putting off cold air. Roy Inch & Sons Service Experts Heating & Air Conditioning is here with some of them to help you detect the issue.

 

  • Thermostat

 

It may 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 HVAC system will blow constantly, even when it isn’t really heating the air coming out, thus blowing cold air. Turning it to “auto” will make sure the heating system only blows when it’s truly heating the air to keep your home warm and comfy.

 

  • Air Filter

 

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

 

  • Duct Work

 

If your duct work includes leaks, connection troubles, or was not designed correctly, it could let warm air from the heating equipment to leak out. This would not only cause your heating equipment to give off cold air, it could significantly run up your utility bills since your furnace is heating non-living space, and will have to work more to keep your home comfortable.
