Malfunctioning Burners in Your Furnace
Posted On: December 6, 2024
Your furnace's burners are critical components that ensure proper heating in your home. When they malfunction, your comfort and safety can be at risk. Let’s explore what causes burner issues, how to identify them, and what you can do to address the problem.
Common Causes of Malfunctioning Burners
- Dirt and Debris Buildup: Over time, dust and grime can clog burners, preventing them from igniting or burning cleanly.
- Faulty Ignition System: A broken ignitor or pilot light failure can prevent burners from lighting.
- Gas Flow Issues: Problems with the gas valve or a disrupted supply can lead to uneven or non-functioning burners.
- Corroded or Damaged Components: Rust or wear on burners or their surrounding parts can impair performance.
Signs Your Furnace Burners Are Malfunctioning
- Delayed Ignition: A loud bang or delay when your furnace starts could indicate gas buildup caused by burner issues.
- Yellow or Flickering Flame: A healthy burner flame should be steady and blue. Yellow flames suggest incomplete combustion or ventilation problems.
- Unusual Odors: Burning smells can indicate dust or debris on the burners. A gas smell may point to a leak and requires immediate attention.
- Insufficient Heat: If your furnace struggles to reach the set temperature, the burners might not be functioning correctly.
How to Address Burner Problems
- Schedule Regular Maintenance: Annual tune-ups can prevent debris buildup and ensure burners operate efficiently.
- Clean Burners: Turn off the furnace, remove the burners, and gently clean them with a brush. Consult your owner’s manual or a technician if unsure.
- Inspect the Ignition System: Check for a working ignitor or pilot light. Replace faulty components as needed.
- Call a Professional: For gas supply issues or extensive repairs, it’s best to contact a licensed HVAC technician.
Why Timely Repairs Are Important
Ignoring malfunctioning burners can lead to:
- Higher energy bills due to inefficient heating.
- Increased risk of carbon monoxide leaks.
- Potential damage to other furnace components.
When to Replace Your Furnace
If your furnace is older (15+ years) and burner issues are recurring, replacing the unit may be a more cost-effective solution.
For reliable furnace repair and maintenance, contact a trusted HVAC professional. Taking proactive steps ensures your home stays warm and safe during the colder months.

Twintech replaced our aging furnace and air conditioner recently. I highly recommend this company. Their quote was competitive, they were on time and respectful of our home and extremely professional. From the salesman to the installers and the owner who followed up afterward to ensure we were satisfied, we are very pleased with the service. We are looking forward to working with this company for all of our HVAC needs for the years to come. Excellent workmanship and service!

We wanted to get our AC replaced as it was 22-years old and added to this our furnace was costing more and more to repair. So, we decided to get both the furnace and AC replaced.
After going through a few quotes and product reviews we decided to go with Twintech. The three-men crew arrived early in the morning, wasted no time and got to work right away. By 2:00 pm, they were all done. IÂ’ve found their work to be top notch and they were completely professional. I had all my questions answered to my satisfaction both during the progress of their work and at end.
I have pleasure in recommending Twintech to anyone who is looking to get their furnace or Ac replaced

Our air conditioner died On a Saturday and within hours Dave came out to take a look and discuss replacement/repair options.
The new air conditioner was installed on the Wednesday. The new unit was installed quickly. The installers were friendly and cleaned up afterwards.
We noticed a slight leak around the furnace that night and they came out the next day and fixed the issue. It has been working great and is quieter than our previous unit.
Very satisfied and would highly recommend TwinTech.

I contacted TwinTech to replace my 20-year old A/C. Dave, their service rep, promptly replied and was at my home within 2 hours. He was friendly and knowledgeable and didn't try to upgrade or oversell their A/C units but suggested the best fit for my small 1000 feet bungalow. Although this was during a heatwave and very busy, they were able to fit me in 2 days later. The TwinTech crew installed a 1.5 ton Ducane A/C unit that is now running smoothly while maintaining a constant cooling temperature. The crew were very courteous, professional and efficient and I will definitely recommend TwinTech to family and friends. I much appreciated your great service.

TwinTech was a pleasure to deal with from the estimate through installation. We replaced a 28 year old a/c unit with one recommended by TwinTech's sales representative Dave who took the time to go over the product with us and answer any questions. The warranty is for 10 years parts and labour and they will complete the registration for you. Installation was by Greg (owner) and Mitch and Spencer who were quick and efficient and left everything clean and tidy.

Very professional, from the sales consultation and inspection to the final installation. Met every expectations we had for the job. A local business with great client support. We highly recommend. Twintech is a blue chip! Thanks!
