Most Common Reasons For Your Furnace Breaking Down
Posted On: November 19, 2024
A furnace breakdown is never convenient, especially during the cold months when you rely on it the most. Here are the most common reasons your furnace might stop working and how to prevent these issues:
1. Dirty or Clogged Filters
When filters are clogged, airflow is restricted, causing the furnace to work harder and overheat. This can lead to wear and tear on internal components.
Solution: Replace filters every 1 to 3 months during heavy use.
2. Thermostat Issues
A malfunctioning or incorrectly set thermostat can prevent the furnace from turning on or maintaining the desired temperature.
Solution: Ensure the thermostat is properly calibrated and the batteries are replaced regularly.
3. Ignition or Pilot Light Failure
Problems with the ignition system or a blown pilot light can prevent the furnace from producing heat.
Solution: Clean or replace the igniter and check for gas supply issues.
4. Lack of Maintenance
Skipping regular maintenance can lead to unnoticed problems, such as dirty burners or worn-out components, which cause the furnace to fail over time.
Solution: Schedule professional maintenance annually to keep your furnace running efficiently.
5. Mechanical Wear and Tear
Moving parts like belts, motors, and bearings can wear out over time, leading to inefficient performance or a complete breakdown.
Solution: Regular inspections can catch wear early, allowing for timely repairs.
6. Blocked or Leaking Ducts
Airflow issues caused by blockages or leaks in the ducts can force your furnace to work harder, eventually leading to a breakdown.
Solution: Inspect and seal ductwork as needed to maintain efficiency.
7. Overworking the System
Setting the thermostat too high or running the system continuously without breaks can overwork the furnace, leading to overheating or damage.
Solution: Use a programmable thermostat to optimize heating schedules and prevent overuse.
8. Electrical Problems
Blown fuses, tripped breakers, or faulty wiring can cause the furnace to stop working altogether.
Solution: Check your electrical panel and wiring connections or call a professional if needed.
9. Dirty Burners
If the burners are dirty, they can’t efficiently ignite and heat your home, leading to uneven heating or no heat at all.
Solution: Have a professional clean the burners during regular maintenance.
10. Aging Furnace
Furnaces typically last 15 to 20 years. As they age, efficiency decreases, and breakdowns become more common.
Solution: Consider replacing your furnace if repairs become frequent and the system is outdated.
Key Takeaway:
Regular maintenance, timely repairs, and proper usage can help extend the life of your furnace and prevent breakdowns. If you encounter issues, it’s best to consult an HVAC professional to diagnose and resolve the problem quickly.

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. Ive 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!

I left a live chat message on their website that my air conditioning was not working. Within 1hr a representative called me to discuss my options.
The next day he came to the house to review my needs and give me a price for a new system. Price quoted was less than I expected and the installation was completed the following day. I found their salesman and the installers very knowledgeable and easy to deal with. All my questions were answered. Everything was properly explained in regards to what unit was needed and why, along with instruction where needed for use.
The installers made sure everything was working properly before they left.

This is to thank Twintech Heating and Cooling for their exceptional and timely service. Mitch, their technician was very courteous and generous with his time right from his first meeting with us. He not only took the time to check everything but also educated us on why we needed what he recommended. Greg and Mitch graciously accommodated us on our requested day and time for job to be done. They were both very courteous and responsive to our needs and special requests especially in a tight spot. The job was finished neatly and on time. Thank you Twintech for your great service !
