Why Your Furnace Could be Blowing Cold Air

You notice your HVAC system start up and you’re anticipating a comfy blast of warm air, but instead all you have is cool air blowing. That’s not preferable in the freezing weather! 

There are a couple reasons why your heating system could be giving off cold air. Service Experts Heating & Air Conditioning is here with some of them to help you find the issue. 

  • Thermostat 

It might seem silly, but the thermostat is where you should start. 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 HVAC system will blow continually, even when it isn’t really heating the air being released, thus blowing cold air. Changing it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and comfortable. 

  • Air Filter 

Typically air filters need to be changed once a month to avoid them from getting dirty and clogged. If air filters aren’t replaced often enough, the clogged air filter may impede airflow into your heating equipment. If this happens, it can overheat your equipment, causing the furnace to stop heating as a safeguard. 

  • Duct Work 

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

There are many other reasons that your heating equipment could blow cold air.
