Why Your Furnace Could be Blowing Cold Air Published on October 21, 2016 You listen to your heating system start up and you’re expecting a cozy blast of warm air, but instead all you get is cool air blowing. That’s not preferable when it’s cold outside! There are a handful of reasons why your heating equipment could be putting off cold air. Barlow Service Experts Heating & Air Conditioning is here with a couple of them to help you find the culprit. Thermostat It may sound silly, but the thermostat is the first thing you want to look at. It’s the starting point for any heating technician, too. Verify the system is set to “auto and not “on.” If the thermostat is set to “on” then your heating system will blow continually, even when it isn’t heating the air coming out, thus putting off cold air. Turning it to “auto” will make sure the furnace only blows when it’s really heating the air to keep your home warm and cozy. Air Filter Typically air filters need to be changed once a month to prevent them from becoming dirty and clogged. If your filters aren’t replaced often enough, the soiled air filter may obstruct airflow into your heating system. If this occurs, it can overheat your system, causing the furnace to stop heating as a safety precaution. Duct Work If your duct work has leaks, connection problems, or was not designed correctly, it could allow warm air from the heating equipment to seep out. This would not only cause your heating equipment to give off cold air, it could actually 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 several other reasons that your heating equipment could blow cold air.
