You hear your HVAC system kick on and you’re expecting a comfortable blast of warm air, but instead all you feel is cool air blowing. That’s not what you want in the freezing weather!
There are a couple reasons why your heating equipment could be putting off cold air. Donelson Air Service Experts is here with a few of them to help you detect the problem.
It may feel silly, but the thermostat is the first place you should check. 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 HVAC system will blow continually, even when it isn’t heating the air being released, thus blasting cold air. Changing it to “auto” will make sure the heating system only blows when it’s really heating the air to keep your home warm and comfy.
Typically air filters need to be changed monthly to prevent them from becoming dirty and clogged. If they aren’t changed often enough, the clogged air filter may obstruct airflow into your furnace. If this happens, it can overheat your system, causing the system to stop heating as a safety precaution.
If your duct work includes leaks, connection troubles, or was not designed properly, it could allow warm air from the furnace to escape out. This would not only cause your furnace to blow cold air, it could significantly run up your utility bills since your heating system is heating non-living space, and will have to work more to keep your home comfortable.
