When temperatures dip below freezing in Omaha, NE, the last thing you want is a furnace that stops working. Unfortunately, when your system is running around the clock, it’s more likely to develop issues. Understanding the most common furnace problems can help you know when to call for professional help before a small issue turns into a breakdown.
1. Dirty or Clogged Air Filters
When air filters become clogged with dust and debris, they restrict airflow, forcing your furnace to work harder to push warm air through your home. This can lead to overheating, short cycling, or even system failure during the coldest nights. Checking and changing your filters every month during heavy use can help your system breathe easier and run more efficiently.
2. Faulty Ignition or Pilot Control
Modern furnaces use electronic ignition systems instead of pilot lights, but both can fail if dirt builds up or components wear out. If your furnace won’t start or shuts down shortly after turning on, the ignition system could be the culprit. Our team can inspect the flame sensor, igniter, or control board to ensure safe, reliable operation.
3. Thermostat Malfunctions
Sometimes, the issue isn’t with the furnace itself but with the thermostat. When a thermostat loses calibration or the batteries die, it can cause short cycling or prevent the system from heating properly. Smart thermostats are great for managing temperature and energy use, but even they need the right settings to work efficiently.

4. Blower Motor or Fan Problems
The blower motor distributes warm air throughout your home. If you hear squealing, rattling, or grinding noises, the motor may be worn or in need of lubrication. Common causes of blower issues include:
- Loose or frayed belts
- Dust buildup on moving parts
- Overheating due to restricted airflow
- Worn bearings or electrical faults
Scheduling preventive maintenance helps catch these problems before they lead to total system failure.
5. Strange Noises and Unusual Odors
Odd sounds or burning smells coming from your furnace are always a reason to call a professional. Banging can signal loose components, while musty or electrical odors may point to wiring or combustion issues. Addressing these signs early keeps your system safe and efficient all winter long.
