Why Your Furnace Could be Blowing Cold Air

You hear your HVAC system start up and you’re expecting 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 putting off cold air. Service Experts Heating & Air Conditioning is here with some of them to help you locate the issue. 

  • Thermostat 

It could feel silly, but the thermostat is the first thing you want to look at. 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 heating system will blow continuously, even when it isn’t heating the air being released, thus blowing cold air. Flipping it to “auto” will make sure the furnace only blows when it’s really heating the air to keep your home warm and comfortable. 

  • Air Filter 

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

  • Duct Work 

If your duct work has leaks, connection issues, or was not designed correctly, it could allow warm air from the furnace to seep out. This would not only cause your heating equipment to give off cold air, it could seriously run up your heating bills since your heating equipment is heating non-living space, and will have to work more to keep your home warm. 

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