Why Your Furnace Could be Blowing Cold Air
You hear your HVAC system start up and you’re expecting a cozy blast of warm air, but instead all you have is cool air blowing. That’s not what you want in the freezing weather!
There are a handful of reasons why your furnace could be blowing cold air. Service Experts Heating & Air Conditioning is here with a couple of them to help you detect the culprit.
It may sound silly, but the thermostat is the first thing you want to look at. It’s the first place any heating system technician will check, too. Confirm the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your heating system will blow constantly, even when it isn’t really heating the air coming out, thus blowing cold air. Changing it to “auto” will make sure the heating equipment only blows when it’s really heating the air to keep your home warm and comfortable.
- Air Filter
Most air filters need to be changed once a month to avoid them from becoming dirty and clogged. If air filters aren’t swapped out often enough, the soiled air filter may obstruct airflow into your heating equipment. If this occurs, it can overheat your system, causing the equipment to stop heating as a safeguard.
- Duct Work
If your duct work contains leaks, connection issues, or was not designed correctly, it could allow warm air from the heating system to escape out. This would not only cause your heating equipment to produce cold air, it could significantly run up your heating bills since your furnace is heating non-living space, and will have to work overtime to keep your home at the desired temperature.
