Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your furnace turn on and you’re expecting a cozy blast of warm air, but instead all you have is cool air blowing. That’s not what you want in the freezing weather!

There are a few reasons why your furnace could be giving off cold air. Peachtree Service Experts Heating & Air Conditioning is here with a couple of them to help you detect the culprit.

 

  • Thermostat

 

It may feel silly, but the thermostat is the first thing you want to look at. It’s the starting point for any heating 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 continuously, even when it is not actually heating the air being produced, thus blasting cold air. Turning it to “auto” will make sure the furnace only blows when it’s truly heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

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

 

  • Duct Work

 

If your duct work contains leaks, connection problems, or was not designed properly, it could allow warm air from the heating equipment to seep out. This would not only cause your furnace to give off cold air, it could significantly run up your energy bills since your heating system is heating non-living space, and will have to work more to keep your home at the desired temperature.
