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 preferable in freezing temperatures!
There are a few reasons why your heating system could be blowing cold air. Service Experts Heating, Air Conditioning & Plumbing is here with a few of them to help you find the problem.
It might 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 instead of “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 blowing cold air. Flipping it to “auto” will make sure the furnace only blows when it’s truly heating the air to keep your home warm and comfortable.
The majority of air filters need to be changed monthly to keep them from growing dirty and clogged. If your filters aren’t swapped out often enough, the soiled air filter may impede airflow into your furnace. If this happens, it can overheat your furnace, causing the equipment to stop heating as a safeguard.
If your duct work has leaks, connection issues, or was not designed properly, it could allow warm air from the heating system to escape out. This would not only cause your furnace to give off cold air, it could significantly run up your energy bills since your heating system is heating non-living space, and will have to work overtime to keep your home warm.
