Why Your Furnace Could be Blowing Cold Air

You notice your HVAC system kick on and you’re anticipating a comfy blast of warm air, but instead all you get is cool air blowing. That’s no good in freezing temperatures! 

There are a handful of reasons why your heating equipment could be giving off cold air. Stevenson Service Experts is here with a few of them to help you find the issue. 

  • Thermostat 

It may sound silly, but the thermostat is the first thing you want to look at. It’s the starting place for any furnace technician, too. Verify the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your HVAC system will blow constantly, even when it is not actually heating the air being produced, thus blowing cold air. Flipping it to “auto” will make sure the heating equipment 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 avoid them from becoming dirty and clogged. If air filters aren’t replaced often enough, the soiled air filter may impede airflow into your furnace. If this occurs, it can overheat your equipment, causing the system to stop heating as a safety precaution. 

  • Duct Work 

If your duct work contains leaks, connection troubles, or was not designed correctly, it could permit warm air from the heating system to escape out. This would not only cause your heating equipment to blow cold air, it could actually run up your utility bills since your heating equipment is heating non-living space, and will have to work more to keep your home warm. 

There are multiple other reasons that your heating equipment could give off cold air. Call Stevenson Service Experts today and we’ll send a professional to diagnose your issue and get your home warm and comfy again in no time.
