You listen to your furnace turn on and you’re ready for a comfy blast of warm air, but instead all you have is cool air blowing. That’s no good in freezing temperatures!
There are a few reasons why your furnace could be blowing cold air. Finch Air Conditioning & Heating is here with some of them to help you detect the problem.
It may seem silly, but the thermostat is where you should start. It’s the starting place for any furnace technician, too. Verify the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your HVAC system will blow continuously, even when it is not actually heating the air coming out, thus blasting cold air. Changing it to “auto” will make sure the furnace only blows when it’s truly heating the air to keep your home warm and cozy.
Most air filters need to be changed once a month to keep them from growing dirty and clogged. If they aren’t swapped out often enough, the soiled air filter may obstruct airflow into your heating system. If this occurs, it can overheat your equipment, causing the equipment to stop heating as a safety measure.
If your duct work has leaks, connection troubles, or was not designed properly, it could allow warm air from the heating system to seep out. This would not only cause your heating equipment to give off cold air, it could seriously run up your energy bills since your furnace is heating non-living space, and will have to work more to keep your home warm.
