Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system kick on and you’re anticipating a cozy blast of warm air, but instead all you feel is cool air blowing. That’s not what you want in the freezing weather!

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

 

  • Thermostat

 

It might seem silly, but the thermostat is where you should start. It’s the first place any heating system technician will check, too. Verify the system is set to “auto instead of “on.” If the thermostat is set to “on” then your furnace will blow continuously, even when it isn’t heating the air being produced, thus blasting cold air. Changing it to “auto” will make sure the heating equipment only blows when it’s truly heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

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

 

  • Duct Work

 

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