A reliable furnace is essential for staying warm during the winter months. So when your furnace stops working, it can be stressful. The good news is that some issues are simple to troubleshoot before you need to call for professional help.
Below are a few common reasons your furnace may stop working and what you can check first.
Common Reasons a Furnace Stops Working
1. Power Supply Issues
If your furnace isn’t turning on, start by checking its power source. Make sure the unit is plugged in, the breaker hasn’t tripped, and the switch near the furnace is in the “on” position.
2. Thermostat Problems
An unresponsive or faulty thermostat can prevent your furnace from starting. Check that your thermostat is powered, set to “heat,” and programmed to a temperature higher than the current room temperature.
3. Dirty or Clogged Filters
A dirty air filter restricts airflow and can cause your furnace to shut down to prevent overheating. Replace or clean your filter regularly to help your system run efficiently and safely.
4. Mechanical Wear and Tear
Over time, normal wear and tear can cause belts, bearings, or other components to fail. If you hear unusual noises or notice your furnace cycling frequently, it may need professional attention.
When to Call a Professional
Some furnace problems should always be handled by an expert. Call a professional if:
- You smell gas or suspect a leak.
- You notice electrical issues or sparking.
- The furnace cycles on and off frequently.
- You hear grinding, banging, or other unusual sounds.
Licensed HVAC technicians have the training and tools to diagnose and repair complex furnace problems safely and effectively.
Preventive Maintenance Tips
Routine maintenance helps prevent your furnace from stopping unexpectedly.
- Schedule annual furnace maintenance before the heating season.
- Replace air filters every 1 to 3 months.
- Keep the area around your furnace clean and clear of obstructions.
- Listen for unusual noises or changes in performance.
