Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your heating system turn on and you’re anticipating a comfortable blast of warm air, but instead all you have 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. Comfortech Service Experts Heating & Air Conditioning is here with a few of them to help you detect the problem.

 

  • Thermostat

 

It may seem silly, but the thermostat is where you should start. It’s the first place any heating system technician will check, too. Confirm the system is set to “auto and not “on.” If the thermostat is set to “on” then your HVAC system will blow continually, even when it isn’t heating the air coming out, thus blasting cold air. Turning it to “auto” will make sure the heating system only blows when it’s really heating the air to keep your home warm and comfy.

 

  • Air Filter

 

The majority of air filters need to be changed once a month to avoid them from getting dirty and clogged. If your filters aren’t changed often enough, the dirty air filter may obstruct airflow into your furnace. If this occurs, it can overheat your system, causing the furnace to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work has leaks, connection problems, or was not designed properly, 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.
