Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system start up and you’re expecting a comfortable blast of warm air, but instead all you get is cool air blowing. That’s no good in the freezing weather!

There are a few reasons why your heating equipment could be putting off cold air. Service Experts Heating & Air Conditioning is here with a couple of them to help you detect the issue.

 

  • Thermostat

 

It could seem silly, but the thermostat is the first place you should check. It’s the first place any heating system technician will check, too. Confirm the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your heating system will blow continually, even when it is not actually heating the air coming out, thus putting off cold air. Turning it to “auto” will make sure the heating equipment only blows when it’s actually heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

Most air filters need to be changed once a month to keep them from growing dirty and clogged. If they aren’t swapped out often enough, the clogged air filter may restrict airflow into your heating equipment. If this happens, it can overheat your system, causing the equipment to stop heating as a safeguard.

 

  • Duct Work

 

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