Most Common Reasons For Your Furnace Breaking Down

Most Common Reasons For Your Furnace Breaking Down

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.

by Anonymous from Pickering on Twintech Heating and Cooling

End to end service. From quote, overseeing installation, contacting and making arrangements for energy audit. Warranty program is comprehensive. Cleaned up mess of assistant walking through my place without proper indoor foot covering when I pointed out that I was not happy about footprints on my floors.

by Bob S in Pickering on Twintech Heating and Cooling

In April we hired Twintech Heating & Cooling to replace our 20 year old water tank & 35 year old air conditioner. We got 5 estimates for the job & decided to go with Twintech for the following reasons.

- The Sales Manager, Dave, was very personable & knowledgeable as all of our questions were answered. (We had a list of questions we asked each of the contractors when we got the estimates)
- We got 5 estimates for the job. All contractors verbally told us they had the required qualifications but Dave was the only one to physically show us their license & insurance documentation.
- Twintech carried the Napoleon air conditioner & we wanted to support Canadian industry as it is assembled in Barrie On.

Safety is important at Twintech as demonstrated when we discussed with Dave, the need to change our install date because of freezing rain. Access was required by navigating a set of outside steps & Dave identified that safety took precedence.
On the installation date, Greg, Peter & Grant showed up on time & methodically accomplished the removal & installation of both units. The guys did a great job cleaning up as well.

When the job was completed we mentioned to Greg that we were pleased with the work they had done & were going to have them come out & do our furnace inspection in Sept. Greg said we can save our money as he had inspected the heat exchanger on the furnace while doing the job & there was no need to have another inspection in Sept. We were very impressed with Greg’s initiative. This is top shelf service. Thank you Greg.

As the weather was too cool to complete a functional test of the air conditioner on the installation date, Dave made a follow-up call to us to see how things were going & Greg also came out to check the operation. No problems.

We are very happy we hired professionals like Dave, Greg, Grant & Peter & have no hesitation in recommending Twintech Heating & Cooling. They will now be our "go to" guys.

These guys are the best. From start to finish they exceeded my expectations and delivered a great product. They accommodated the nuances of my 100 year old home which was really appreciated. The install was easy to schedule and done fantastically. I’m so excited to have an efficiently heated and cooled home.

by Private User from Kitchener on Twintech Heating and Cooling

Twintech were fast and efficient contractors. It only took 48 hours between an initial home visit and complete installation. The workmen were polite and hardworking. The site was left clean with the old furnace etc. removed. They helped arrange an environmental assessment in order that I could receive the maximum rebate. They even called me within a week to determine if I was satisfied with their work and to reassure me that I could call them anytime I experienced heating difficulties or had any questions. I recommend Twintech for your heating problems.

by dlcarroll in Vaughan on Twintech Heating and Cooling

Courteous and professional service from initial consultation through to the installation. We highly recommend Twintech for outstanding service in the industry. Competitive pricing, professional and accurate advice, attention to detail, respect for their client's home and cleaning up at the completion of installation.

by TraceyG from Toronto on Twintech Heating and Cooling

Last night was the coldest day of the year so far and I woke up to my house being 54 degrees... I called Twintech at 2:45am and Greg was on site by 3:30am. The furnace required a part and he returned to his shop and came back to my home around 4:15am, furnace up and running by 4:30am. THANK YOU TWINTECH! Your service is second to none.

by Cristelle from Ajax on Twintech Heating and Cooling

After much research & getting 4 quotes, we hired Twintech team for our new furnace installation, prices were fair, they carried great product brands & more importantly installation was expertly done by one of the owners (Greg & his assistant Peter) which gave me an added piece of mind. Dave was very organized & answered all my questions in great detail, especially re: the Enbridge & Govt. rebate program.

by David from Pickering on Twintech Heating and Cooling

My old air conditioner was 20 years old and developed a Freon leak and it was more cost effective to replace rather than repair. There are a large number of heating and air conditioning companies available in my area so I contacted several for quotes. Twintech heating and cooling responded quickly to the inquiry I left on their website and their sales person Dave came by the following day. He was knowledgeable about the field and was able to show copies of the various refrigeration and gas fitting licenses along with workmens compensation, TSSA and other certifications. He also suggested a particular manufacturer and model of AC unit appropriate to my house and gave me a quote. Since the price was reasonable, service had been good and the reviews on the internet were also good, I decided to purchase an AC unit from them. Installation was quickly scheduled. They showed up on time, did a good job installing the new unit including some sheet metal work to get the new heat exchanger to fit in the furnace duct, and cleaned up afterward. In addition, they noticed that my existing AC was installed too close to the furnace exhaust (based on building code) and were able to mount the new AC the appropriate distance from the exhaust. Overall, they did an excellent job and were a pleasure to work with.

by LP from Pickering on Twintech Heating and Cooling

All interactions from sales to installation were Courteous and professional. The installation was seamless and the attention to detail including clean up was outstanding. I highly recommend TwinTech Heating and Cooling.

by David in Pickering on Twintech Heating and Cooling

Twintech's Salesman Dave arrived promptly was friendly and courteous, listened and assured us the installation would be completed according to our requests. The crew arrived early morning on May 11th, 2018 and worked through till late afternoon non-stop. They were very friendly, very professional, their expertise was excellent, their workmanship outstanding and the installation was completed in a timely and efficient manner. We were completely satisfied and happy with the quality of the work.
