Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system start up and you’re ready for a comfy blast of warm air, but instead all you get is cool air blowing. That’s not what you want in freezing temperatures!

There are a couple reasons why your heating equipment could be blowing cold air. Midway Services is here with some of them to help you detect the problem.

 

  • Thermostat

 

It could seem silly, but the thermostat is the first thing you want to look at. It’s the starting point for any heating technician, too. Make sure the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your HVAC system will blow continuously, even when it is not actually heating the air coming out, thus putting off cold air. Changing it to “auto” will make sure the heating system only blows when it’s really heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

The majority of air filters need to be changed monthly to avoid them from getting dirty and clogged. If your filters aren’t swapped out often enough, the soiled air filter may impede airflow into your furnace. If this occurs, it can overheat your equipment, causing the system to stop heating as a safety precaution.

 

  • Duct Work

 

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