With winter in full swing in Palatine, IL, the last thing you want is for your furnace to blow cold air. There are several reasons this might happen; and these are some of the common reasons your furnace is blowing cold air.
Problems That Aren’t a Big Deal
It’s understandable to think the worse when HVAC issues pop up. Yet, sometimes, when vents expel cold air, but the furnace seems to run well, the problem isn’t mechanical. Instead, any of the following could hinder the furnace’s heat output:
- Incorrect thermostat settings
- Clogged air filter
- leaking ductwork
An HVAC technician can help you troubleshoot any of these problems and help you understand why your vents are blowing cold air.
Problems That Are More Complicated
After you’ve determined the problem isn’t thermostat-related or caused by blocked vents or dirty filters, the next action is to call for professional troubleshooting and diagnostic services. A technician can get to the source of the problem quickly and get your home warm and toasty again in no time.
A technician first checks the ignition system to ensure it’s not malfunctioning. If you have a gas furnace, the burners may not be fully igniting.
Burners that don’t fully ignite often have this problem because they’re not getting adequate gas supplies. The tank might need filling if a propane tank supplies gas to the home. Clogged burners can also cause ignition problems, which are easily solved by cleaning them.
When those problems aren’t present, the technician will check the ductwork for any damage. Ductwork that isn’t sealed well or has holes will leak air. The heated air escapes before it ever gets to your vents, and that’s why the furnace seems like it’s blowing cold air.
