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 feel is cool air blowing. That’s not what you want when it’s cold outside!

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

 

  • Thermostat

 

It may feel silly, but the thermostat is where you should start. It’s the first place any heating system technician will check, too. Make sure the system is set to “auto instead of “on.” If the thermostat is set to “on” then your heating system will blow constantly, even when it isn’t heating the air coming out, thus blasting cold air. Flipping it to “auto” will make sure the heating system only blows when it’s truly heating the air to keep your home warm and cozy.

 

  • Air Filter

 

Typically air filters need to be changed once a month to avoid them from growing dirty and clogged. If air filters aren’t swapped out often enough, the dirty air filter may obstruct airflow into your heating system. If this happens, it can overheat your system, causing the equipment to stop heating as a safety precaution.

 

  • Duct Work

 

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