You listen to your heating system kick on and you’re anticipating a cozy blast of warm air, but instead all you get is cool air blowing. That’s not what you want when it’s cold outside!
There are a couple reasons why your heating system could be blowing cold air. TML Service Experts is here with some of them to help you detect the issue.
It might seem 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 instead of “on.” If the thermostat is set to “on” then your HVAC system will blow continually, even when it isn’t really heating the air being released, thus blasting cold air. Flipping it to “auto” will make sure the heating equipment only blows when it’s truly heating the air to keep your home warm and comfy.
The majority of air filters need to be changed every month to keep them from becoming dirty and clogged. If air filters aren’t swapped out often enough, the soiled air filter may restrict airflow into your heating equipment. If this happens, it can overheat your furnace, causing the furnace to stop heating as a safeguard.
If your duct work includes leaks, connection problems, or was not designed properly, it could let warm air from the furnace to seep out. This would not only cause your heating system to produce cold air, it could significantly run up your heating bills since your heating system is heating non-living space, and will have to work more to keep your home warm.
