Why Your Furnace Could be Blowing Cold Air
You listen to your HVAC system turn on and you’re anticipating a comfortable blast of warm air, but instead all you have is cool air blowing. That’s no good in the freezing weather!
There are a handful of reasons why your heating equipment could be giving off cold air. San Antonio Air Service Experts is here with a few of them to help you locate the culprit.
It may feel silly, but the thermostat is the first thing you want to look at. It’s the starting point for any heating technician, too. Make sure the system is set to “auto and not “on.” If the thermostat is set to “on” then your furnace will blow continuously, even when it is not actually heating the air being released, thus putting off cold air. Changing it to “auto” will make sure the heating system only blows when it’s truly heating the air to keep your home warm and cozy.
- Air Filter
The majority of air filters need to be changed once a month to prevent them from getting dirty and clogged. If your filters aren’t changed often enough, the soiled air filter may obstruct airflow into your furnace. If this happens, it can overheat your system, causing the equipment to stop heating as a safety precaution.
- Duct Work
If your duct work contains leaks, connection troubles, or was not designed correctly, it could let 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 heating bills since your heating equipment is heating non-living space, and will have to work overtime to keep your home at the desired temperature.
