Why Your Furnace Could be Blowing Cold Air

You notice your heating system kick on and you’re expecting a cozy blast of warm air, but instead all you have is cool air blowing. That’s not preferable in the freezing weather! 

There are a few reasons why your heating system could be blowing cold air. Service Experts Heating & Air Conditioning is here with a few of them to help you locate the culprit. 

  • Thermostat 

It may seem silly, but the thermostat is where you should start. 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 HVAC system will blow constantly, even when it isn’t heating the air coming out, thus putting off cold air. Changing it to “auto” will make sure the heating system only blows when it’s truly heating the air to keep your home warm and comfy. 

  • Air Filter 

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

  • Duct Work 

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

There are many other reasons that your heating system could produce cold air. Call Service Experts Heating & Air Conditioning today and we’ll send a technician to diagnose your issue and get your home warm and comfy again in no time.
