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.

I had a problem with the Furnace (Armstrong ultra V) and Greg diagnosed it on the phone. Even told me what the issue was and I was able to fix it. This level of service from a Business that is almost unknown today.
If you require service, reach out to Greg. I will definitely use them in the future!

We have been shopping for a heat pump for our home. We had 3 reps come in and make recommendations and provide a quote. Of the 3, Bob was so clearly so much more qualified, thorough and informed than the other two that the decision was a no brainer. As soon as we get our audit results Twintech will be installing our heat pump.

knowledgeable sales person, did not try to up-sell unneeded features,
and was easily contacted to ensure customer satisfaction.
Installation was expertly done by friendly guys, everything explained for use of the products. Old products were removed and returned to rental company as part of the service. Follow up call was received to check all was well. This is my second time using this company as I was fully satisfied with my previous air conditioning unit installation

Twintech recently installed a new furnace for me. Bob did a great job assessing what I had and needed. All details well explained including the importance of proper sizing of furnace and the value of multi stage heating and the variable speed blower. As a nurse, indoor air quality is a high priority so the variable speed motor running continuous is so good. 24/7 air cleaning. Greg did a great job on install, attention to detail so appreciated. Already notice such an improved comfort and heat. Thank you Twintech! You come as advertised. I will recommend to anyone in need of heating or cooling!

We received various quotes from 4 different companies and right away, the prompt and thorough communication from Bob from TwinTech stood out. He introduced himself, sent sample sites and information, and always confirmed any agreed to dates and times.
Bob was friendly and extremely knowledgeable about the topic of HVAC and it was clear he was passionate about his profession. He approached the job as if he was installing in his own home.
Prior to the new furnace & A/C installation, our old units were loud and inefficient - having several rooms feeling too cold in the winter and too hot in the summer. After installing the recommended units, all rooms stay at a consistent temperature- even the finished basement.
I highly recommend the TwinTech team - just an outstanding job at a reasonable price point.

The experience with Twintech was great from the start. Bob the sales manager was friendly and professional and did not use any pressure tactics. He was very knowledgeable.
The installation was completed by the twin owners in about 6-7 hours. Clean quiet easy going didn't mind when I poked my head in to see progress. Highly recommend

Just choose Twintech!
I do not usually write reviews and should have done this a few days sooner. But I was and still am enjoying the increased comfort in my home from the new furnace installed by Twintech.
From my initial call and conversation with Bob, I already had a good feeling that I would like this company.
I was provided information, pictures of great quality work previously completed.
When Bob came for the inspection of the furnace he was amazing. He gave so much great advice and told me all the areas that his team would resolve. I was very impressed as some of what he had suggested I had only seen in Youtube videos. The honesty and options for payment made this a no brainer. I decided I would like Twintech to replace my furnace.
The work was scheduled promptly week and took place within half a day. Gregg came to install the new furnace. Again amazing they carried out all the work promised. What was left was the best I have seen and speaks to how they take pride in the work they do and deliver. Gregg was really polite and professional and the furnace in my basement is a work of art.

They were friendly, fast, clean, & answered any questions I had. They are also offering an interest free 12 month payment plan - that really helped me out since this was an unexpected expense.

I had Twintech heating install a new furnace and ac unit. Bob, the sales rep, the installation team of Greg and Mitch were a 10 across the board. They were never pushy, gave me time to think about it. Once we decided , they were there in 24hrs. Great company to deal with. And they were nearly 5k less than a competitors quote for a top of the line furnace/ac unit verse mid level.
I highly recommend Twintech heating to anyone interested in anything HVAC.
