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.

Twintech Heating & Cooling installed my furnace in 2022 and in fall of 2023 installed my Panasonic Heat Pump. Greg and Mitch did a great job. Helped me through the rebate process. Super happy with the Heat Pump. Only used my furnace 5 times this winter. Energy bills lower, carbon emissions lower.Thank you Twintech. I recommend highly!

They've cleaned my furnace a couple of times and mentioned that the hot water tank standards were going to change soon so I decided to change mine out.
There were a few challenges during the process but the installers handled the problems without missing a stride! I now have really hot water again!

Highly recommend Twintech Heating company, we got honest and detailed information on what was needed to replace and install a new gas furnace. Bob and Greg made us feel comfortable withe process through their thorough explanation and knowledge of the right furnace for our needs. The professionalism and courteous friendly attitude towards the customer is what we liked the most as they treated us like family. So happy with our decision and new furnace we will be looking into get our rental water heater replaced and installed by Twintech team. We feel better having their knowledge on our side and will only trust them with any further maintenance of furnace.

Customer service and knowledge is priority in this industry, and Twintech has it. I've dealt with their team for maintenance and a furnace replacement. They're accommodating and make great recommendations, and came through at a great price over the big guys in the industry. They'll be my next call when I need service or maintenance.

I decided that the noises and age of the existing furnace which was old and not very efficient to replace it. Gave Greg a call and Grant and Greg got to work on it. Because of supply issues with the current heating type that would be an easier install Greg convinced me to change the location of the system and it would provide me better service for heat and efficiency. I had skeptical but went ahead anyway putting trust in Greg And Grant. Greg, Grant and Mitch came through and in 2 days had completely relocated my heating and A/C system. I can honestly say Greg was right my old house has been warmer and more evenly heated as it ever was. For anyone reading this rather long winded review can take my word for it, Twin Tech can take care of your needs.

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!

Great Team! Furnace broke in the weekend, Bob visited same day and Greg installed new one on Monday. Team was professional, respectful and knowledgeable. Installation went very well, Greg found solutions to challenges, like hiding new conduits in the ceiling. Looks nice and new furnace is working great. Five Stars.

I used Twintech to install a new furnace for my home. Bob was terrific in explaining the sizing options and why the 2 stage furnace was the best option for me. Greg did a great job installing, clean and on time. Finished work looks great but the best part is how it works. The 2 stage heating is so much more comfortable. I run the fan continuously to keep the indoor air clean. Great investment! Would highly recommendTwintech!

Im going to start this by saying Im a very particular customer. My background is in mathematics and mechanical engineering so I have an eye for detail and a respect for technical knowledge.
Greg had already done an AC inspection and replaced a water heater tank and there was no question in my mind who to deal with replacing my rickety old furnace after it got pooched.
Bob dropped in ahead of time and clearly (and knowledgeably) outlined all technical, price and operational options.
Greg showed up on time, on the agreed date and did a fantastic job. (The OLD furnace was a house of horrors and was installed in a keystone cops sort of way- careless.)
The work Greg did was HIGHLY PROFESSIONAL and FAR MORE FUNCTIONAL than what I had.
Im also a musician with many instruments so maintaining predictable humidity/temperature is extremely important to me. Greg recognized this as did Bob. You NEVER feel like youre being brushed off.
In summary, if youre looking for PROFESSIONAL, QUALITY results by an EXPERIENCED, THOUGHTFUL team
(that also happen to be FRIENDLY and ATTENTIVE ) then youve come to the right page!!
