You notice your furnace kick on and you’re expecting a comfortable blast of warm air, but instead all you feel is cool air blowing. That’s not preferable in freezing temperatures!
There are a couple reasons why your heating system could be blowing cold air. Bob Brown Service Experts is here with some of them to help you find 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 and not “on.” If the thermostat is set to “on” then your heating system will blow constantly, even when it is not actually heating the air being produced, thus blasting cold air. Changing it to “auto” will make sure the furnace only blows when it’s really heating the air to keep your home warm and comfy.
The majority of air filters need to be changed once a month to keep them from growing dirty and clogged. If your filters aren’t replaced often enough, the dirty air filter may restrict airflow into your furnace. If this occurs, it can overheat your furnace, causing the equipment to stop heating as a safety precaution.
If your duct work contains leaks, connection problems, or was not designed correctly, it could allow warm air from the heating equipment to leak out. This would not only cause your heating system to give off cold air, it could significantly run up your energy bills since your heating equipment is heating non-living space, and will have to work overtime to keep your home comfortable.
