You hear your furnace start up and you’re anticipating a comfortable blast of warm air, but instead all you have is cool air blowing. That’s not what you want when it’s cold outside!
There are a couple reasons why your furnace could be blowing cold air. Service Experts Heating, Air Conditioning & Plumbing is here with a couple of them to help you find the issue.
It could feel silly, but the thermostat is the first place you should check. 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 furnace will blow continuously, even when it isn’t heating the air being produced, thus blowing cold air. Turning it to “auto” will make sure the furnace only blows when it’s actually heating the air to keep your home warm and comfy.
Most air filters need to be changed every month to avoid them from growing dirty and clogged. If your filters aren’t changed often enough, the clogged air filter may restrict airflow into your furnace. If this happens, it can overheat your system, causing the system 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 furnace to give off cold air, it could significantly run up your utility bills since your furnace is heating non-living space, and will have to work more to keep your home at the desired temperature.
