Top Furnace Problems We Fix to Keep Your Home Cozy
Over time, furnaces can develop a range of issues that reduce efficiency and compromise performance. A properly functioning furnace is important for keeping your home warm and comfortable, especially during colder months. At Stewart Heating Plumbing Air Conditioning, we specialize in diagnosing and repairing all types of furnace problems to ensure your system runs smoothly. Here are some of the most common furnace issues we handle:
No Heat or Insufficient Heating
When your furnace is running but failing to generate enough heat, it could be due to several underlying causes:
Causes:
- Faulty Thermostat
- Clogged Air Filters
- Malfunctioning Pilot Light or Ignition System
- Blocked or Leaky Ductwork
- Malfunctioning Blower Motor
Solution:
Regular maintenance, including checking the thermostat, cleaning or replacing air filters, inspecting ductwork, and scheduling professional servicing, can help ensure consistent and efficient heating.
Frequent Cycling (Turning On and Off Repeatedly)
If your furnace turns on and off frequently than usual, known as short cycling, it may be struggling with underlying issues.
Causes:
- Dirty Air Filter
- Misconfigured Thermostat
- Oversized Furnace
- Blocked Vents or Registers
- Flame Sensor Issues
Solution:
Regularly replacing air filters, ensuring proper thermostat placement, and having a professional assess the system for size and efficiency issues can help prevent short cycling.
Unusual Sounds
Furnaces should operate with minimal noise. If you hear unusual sounds like banging, squealing, or rattling, it often indicates mechanical problems.
Causes:
- Banging or Popping Noises
- Squealing or Screeching
- Rattling or Vibrations
- Booming Noises
Solution:
If you hear any strange sounds, turn off your furnace and schedule an inspection. Routine maintenance and timely part replacements can help prevent these issues.
Pilot Light Problems
The pilot light plays an important role in igniting the burners in older gas furnaces. If it flickers or turns yellow, it could indicate serious problems.
Causes:
- Carbon Monoxide Leak
- Dirty or Faulty Thermocouple
- Gas Supply Issues
- Ventilation Problems
Solution:
If your pilot light appears yellow or flickers, turn off the furnace and contact a professional immediately. Proper ventilation and regular furnace maintenance can help prevent pilot light issues.
High Energy Bills
A sudden increase in heating costs often signals inefficiencies in your furnace’s operation.
Causes:
- Dirty or Clogged Filters
- Aging Furnace Components
- Leaky or Poorly Insulated Ductwork
- Inadequate Maintenance
- Malfunctioning Thermostat
Solution:
Regular tune-ups, replacing filters, sealing duct leaks, and upgrading an outdated furnace can significantly improve energy efficiency and reduce heating costs.
Understanding the root causes of common furnace problems can help homeowners take preventative action and schedule timely repairs. We specialize in professional furnace repair services in Brentwood, CA, ensuring your system operates efficiently and reliably.

Proactive Furnace Maintenance: Tips to Prevent Costly Repairs
Routine furnace maintenance is key to keeping your heating system running efficiently, extending its lifespan, and avoiding unexpected breakdowns. Here are some essential maintenance tips to keep your furnace in peak condition year-round:
- Replace Air Filters Regularly: A dirty or clogged air filter can block airflow, making your furnace work harder and lowering its efficiency. To keep your system running smoothly, change your filters every 1–3 months, or more often if you have pets or suffer from allergies.
- Schedule Professional Furnace Tune-Ups: Annual professional inspections help catch minor issues before they turn into significant problems. A certified technician will check for worn-out components, clean internal parts, and ensure everything is operating safely and efficiently.
- Keep Vents and Ducts Clear: Blocked or dirty vents and ductwork can disrupt airflow, leading to uneven heating and increased strain on your system. Regularly vacuum vents, remove obstructions, and schedule duct cleaning as needed to maintain proper circulation.
- Check and Calibrate Your Thermostat: An inaccurate thermostat can lead to temperature inconsistencies and increased energy use. Test your thermostat periodically, replace the batteries if needed, and consider upgrading to a programmable or smart thermostat for better efficiency.
By following these simple yet effective maintenance tips, you can maximize your furnace’s efficiency, reduce the risk of breakdowns, and enjoy a warm, comfortable home all season long.
