Why Your Furnace Could be Blowing Cold Air

You hear your heating system turn on and you’re anticipating a cozy blast of warm air, but instead all you have is cool air blowing. That’s not what you want in freezing temperatures! 

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

  • Thermostat 

It may sound silly, but the thermostat is where you should start. It’s the starting place for any furnace technician, too. Make sure 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 isn’t heating the air being released, thus putting off cold air. Turning it to “auto” will make sure the heating system only blows when it’s really heating the air to keep your home warm and cozy. 

  • Air Filter 

Most air filters need to be changed once a month to avoid them from growing dirty and clogged. If they aren’t swapped out often enough, the clogged air filter may obstruct airflow into your heating system. If this occurs, it can overheat your furnace, causing the system to stop heating as a safety measure. 

  • 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 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 overtime to keep your home comfortable. 

There are several other reasons that your heating equipment could give off cold air.
