Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your HVAC system turn on and you’re anticipating a comfortable 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 few reasons why your heating equipment could be giving off cold air. Service Experts Heating & Air Conditioning is here with some of them to help you find the culprit.

 

  • Thermostat

 

It may feel silly, but the thermostat is the first thing you want to look at. 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 continuously, even when it is not actually heating the air being produced, thus putting off cold air. Turning it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and cozy.

 

  • Air Filter

 

Typically air filters need to be changed monthly to prevent them from getting dirty and clogged. If they aren’t changed often enough, the dirty air filter may impede airflow into your heating system. If this takes place, it can overheat your furnace, causing the equipment to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work includes leaks, connection problems, or was not designed correctly, it could permit warm air from the furnace to leak out. This would not only cause your furnace to produce cold air, it could seriously run up your heating bills since your furnace is heating non-living space, and will have to work overtime to keep your home warm.
