Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC 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 in the freezing weather!

There are a handful of reasons why your heating equipment could be giving off cold air. San Antonio Air Service Experts is here with a few of them to help you locate the culprit.

 

  • Thermostat

 

It may sound silly, but the thermostat is the first thing you want to look at. It’s the starting point for any heating technician, too. Confirm the system is set to “auto and not “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 released, thus putting off cold air. Turning it to “auto” will make sure the furnace only blows when it’s actually heating the air to keep your home warm and cozy.

 

  • Air Filter

 

Most air filters need to be changed once a month to prevent them from becoming dirty and clogged. If your filters aren’t changed often enough, the soiled air filter may obstruct airflow into your furnace. If this occurs, it can overheat your furnace, causing the equipment to stop heating as a safeguard.

 

  • Duct Work

 

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