During the cold months, homeowners rely heavily on their furnaces to keep their homes warm and comfortable. However, some homeowners may be shocked when they find their furnace blowing cold air.
Causes of Cool Air Output
The first step to fixing a problem is to figure out what’s causing it to happen. When a furnace produces cool air, some homeowners may assume their entire system is busted. This isn’t always the case. You may not need a heater repair depending on why your furnace is blowing out cold air.
Dirty Air Filter
If your air filter has become clogged with dust, dirt or other materials, it may be preventing the output of warm air. A dirty air filter can force your system to work harder, which can put a strain on its internal parts. In some cases, the air may come out cold or not at all. Replacing this filter is the best way to solve this problem.
The thermostat is responsible for sending signals to the system to blow out warm air to reach a certain temperature. If the thermostat isn’t working as it should, the air may come out cold. This can be fixed with a simple thermostat repair or replacement.
Control Panel Issues
Something as simple as a problem with your electrical control panel may be causing your furnace to blow out cool air. If turning it off and on again doesn’t solve the problem, don’t attempt any further troubleshooting methods, as electrical work is dangerous for those who aren’t professionals.
When Should You Call a Professional?
You should call an HVAC professional when the safe troubleshooting methods don’t work. If you suspect the issue has something to do with the pilot light or electrical panel (beyond turning it off and on again), then it’s time to step back and let a pro take over.
Furnaces are complex systems. If you aren’t an HVAC technician, it can be easy to damage the unit or harm yourself. In severe cases, you may “fix” the issue incorrectly and cause a fire or other serious outcomes.
However, issues that are best left to professionals don’t always mean it’s a serious problem. A technician may be able to quickly resolve the issue and get your heater blowing out warm air in no time.
How Can This be Prevented?
The best way to prevent a problem like this is to schedule regular tune-ups for your furnace at least twice a year. Heater maintenance can help catch and resolve small issues before they evolve into big ones, such as the output of cold air instead of warm air.
Tune-ups can also benefit you by:
- Saving money on repairs
- Saving money on energy bills
- Extending system’s lifespan
