Common Furnace Fire Hazards

Posted On: November 3, 2024

Common Furnace Fire Hazards

As temperatures drop and winter approaches, your furnace becomes the heart of your home’s warmth and comfort. But as you crank up the heat, it's important to ensure that your furnace is safe to operate. A poorly maintained or malfunctioning furnace can present significant fire hazards, putting your home and family at risk. Here, we’ll discuss the top warning signs to watch for and ways to maintain a safe, efficient heating system.


Common Furnace Fire Hazards

Several factors can turn a furnace into a potential fire risk. Some of the most common include:


  1. Dust and Debris Accumulation
    Dust, dirt, and debris can accumulate in and around your furnace, especially if it hasn't been used for several months. This buildup can cause components to overheat, potentially igniting nearby materials. Regularly cleaning the area around your furnace and changing filters can mitigate this risk.


  2. Gas Leaks
    Gas furnaces run the risk of leaking flammable gases. A gas leak not only increases the risk of a fire but also poses a serious risk of carbon monoxide poisoning. If you notice a rotten egg smell near your furnace, turn off the system immediately, ventilate the area, and contact a professional for an inspection.


  3. Electrical Issues
    Wiring problems or loose connections can cause electrical shorts, sparking fires. Over time, electrical components can wear out or become damaged, especially if the furnace is older. Regular inspections by a licensed technician can help detect and fix any potential electrical hazards.


  4. Overheating
    When a furnace overheats, it can cause components to melt or spark, potentially igniting a fire. A clogged air filter, restricted airflow, or malfunctioning parts can all cause overheating. Monitoring your furnace's temperature and scheduling routine maintenance can help prevent this issue.


Warning Signs Your Furnace May Be a Fire Hazard

It’s essential to be aware of signs that your furnace might be malfunctioning or posing a fire risk. Here are the top indicators to watch out for:


  • Burning Odors: If you smell something burning when the furnace is running, this could mean dust is burning off (which is normal during the first use of the season). However, if the smell persists, it could signal an overheating motor or electrical issue.


  • Yellow or Flickering Pilot Light: The pilot light on a gas furnace should burn blue, which indicates a healthy mix of fuel and air. A yellow or flickering flame can suggest excess carbon monoxide or an improper fuel mixture, which can be a fire hazard.


  • Frequent Cycling: If your furnace is turning on and off more frequently than usual, it could be due to a clogged filter, overheating, or thermostat issues. Frequent cycling stresses the system, making it more susceptible to breakdowns and hazards.


  • Unusual Sounds: Loud bangs, rattles, or grinding noises can indicate parts are loose, damaged, or not functioning correctly. Address these sounds promptly with a professional inspection to avoid fire hazards.


Essential Furnace Maintenance Tips for Fire Prevention

Routine furnace maintenance is the best way to reduce fire hazards and keep your home safe. Here are some steps you can take to minimize risks:


  1. Schedule Annual Inspections
    A licensed HVAC professional should inspect your furnace yearly to catch any signs of wear, damage, or malfunctioning parts. These inspections help identify potential hazards before they become serious problems.


  2. Replace Air Filters Regularly
    Dirty or clogged air filters can restrict airflow, leading to overheating. Replace your filters every 1–3 months, especially during high-usage periods, to ensure your furnace is operating efficiently and safely.


  3. Keep the Area Around the Furnace Clear
    Flammable items like boxes, fabrics, or cleaning supplies should be stored away from the furnace. This minimizes the risk of anything catching fire if the furnace overheats.


  4. Install Smoke and Carbon Monoxide Detectors
    Both smoke and carbon monoxide detectors are essential for detecting issues with your furnace. Install these devices near the furnace and test them regularly to ensure they are in working order.


  5. Monitor the Pilot Light
    As mentioned, the pilot light should burn blue. If it changes color or behaves erratically, have it checked by a professional.


When to Call a Professional

If you notice any of the warning signs or if your furnace hasn’t been serviced in over a year, it’s time to call a professional. Qualified HVAC technicians can assess your system, clean out debris, replace faulty parts, and ensure your furnace operates safely. Never attempt to fix gas lines, wiring, or internal furnace components on your own, as this can be dangerous.


Final Thoughts

Your furnace is vital for keeping your home warm and comfortable, but it’s essential to keep it in good condition to avoid potential fire hazards. Regular maintenance and attention to warning signs will ensure your furnace operates safely throughout the cold season. Remember, a little preventative care can go a long way in safeguarding your home and family from fire risks.

by Jiri in Toronto on Twintech Heating and Cooling

From the initial contact we had an excellent experience with this company and all its personnel. Dave Gergley was an excellent, helpful, sales person and solicitous of our needs. He recommended only what was required and did not up sell or make any suggestions for products that we did not need, such as a new A.C. He explained the rebate process and basically outlined how to get the best furnace at the lowest price. When it was time for installation, the technicians could not have been more considerate, careful, attentive to detail, obviously committed to safety and optimum functioning of the appliance they were setting up. We have been perfectly satisfied with the functioning of the furnace and all aspects of acquiring it from the initial contact with Dave through to the installation process and follow ups inquiring about our satisfaction. Also they initiated the rebate process and contacted the appropriate inspection agency to carry it out. We highly recommend this company for all heating and cooling needs and we will contact them again when it is time to replace our A.C.

by Drew in Pickering on Twintech Heating and Cooling

Twintech was excellent from the initial quote and throughout the install. They had a competitive rate for hot water tank and ended up buying the tank from them, had them remove the old tank and install the new one. The day of install they were prompt and out in about 2 hours. Professional , courteous really great guys. We took a look at my 30 year old furnace and they were able to offer some suggestions for future there too.

by Harry in Toronto on Twintech Heating and Cooling

Ever since I turned on my furnace on Oct 2018 I hear a humming sound when the furnace fan kicks in. I called Adamson Air System who installed my furnace 7 years ago and couldn't figure it out the problem. I just wasted money to the guy who couldn't figure it out. I found Twin Tech via Amana / Goodman website. I checked the reviews from previous Twin Tech customers. I called Greg and was onsite on time this morning Sunday, Nov 25 2018. He figured it out what's wrong with the furnace and explained what the previous installer (adamson air system) did wrong when they installed it. His knowledgeable about his job. He recommend to replace the fun motor because the sound is not normal when it's running. Looking forward to see him again to replace the fan motor.

by Roger in Pickering on Twintech Heating and Cooling

Our house is over 22 years old and I had been researching furnaces and A/C brands for a while and thought it was time to take the plunge. After calling three different companies to come in and quote the job, this one won me over. From the first visit from Dave all the way to the end of the install by Greg, Grant, and Piotr, I was glad to have picked this company. Dave was very knowledgeable and really took the time to explain what kind of quality installation I was going to get as well as showing me some of their previous work and certificates.

I was also surprised at how quick the installation took and how nice everything looked afterward, I mean it's only a furnace right? They even re positioned the furnace so that I have easier access to my filter and humidistat, awesome! If you are looking for a company that cares about their customers and is proud about the quality of work they do, along with a great and competitive price, then stop right here because you found it.

by Louis in Pickering on Twintech Heating and Cooling

Once our AC Unit started to fail, I called our past Heating & Cooling provider for support. The response was we needed a new motor for our Furnace. It was time to check their Quote against the marketplace, I reached to other providers online. One of the owner of Twintech (Greg), called me and offered a preliminary Quote and recommendation online. The others needed to set an appointment and came to measure and spend 1 hour before offering a quote. Then I asked Twintech to come finalize their quote to make sure their recommendation was aligned and met our needs.

Twintech was professional throughout the process, easy to deal with (Web, Phone and in Person), price right and met their commitment. Their team expedited the process and installation, arranged for a energy assessment for available rebates and most importantly, delivered on their commitment and managed to do a few extras. They installed a New Furnace, AC unit and Nest thermostat in a day, remove all older units, left the house and outdoors clean and without any debris. Great to be able to support a Local Company, Neighbour and Professional team - Well Done Team Twintech !!!

by Elizabeth and John L from Scarborough on Twintech Heating and Cooling

In October 2018, I contacted Greg at Twintech to do a furnace cleaning. Greg discovered that my furnace, installed in 2006 by another company, had been installed incorrectly, leading to restricted air flow. The heat exchanger was also defective. As well, my furnace was too large for the size of my house.

In my opinion, the biggest concern most of us have as consumers is that we have no idea of the quality or knowledge and experience of the technicians any heating and cooling company will send into our homes. I could have avoided having my 2006 furnace installed improperly (leading to early replacement), had I known about Twintech then.

With Twintech you get it all. Because Twintech is a smaller company you can rest assured that the only technicians who will work in your home are Greg and his twin brother Grant who are co-owners and fully licensed and certified with over 30 years of experience in installing and servicing heating and cooling equipment. They are both friendly and personable and answer all your questions. Their workmanship is outstanding. We had a 2 stage, variable speed Goodman furnace installed. My wife and I noticed a difference in the heating and even temperature of our 2 storey home almost immediately. Our old furnace always heated too much on the main floor and too little upstairs. We are also impressed with how quiet the furnace is.

Twintech's office manager, David Gergley, is equally friendly and not only gave us a competitive quote to replace our furnace (we sought other quotes), but also went above and beyond my expectations when he made arrangements with an energy audit company so that we would be considered for a grant from Enbridge and IESO.

Needless to say, I give Twintech a 10 out of 10 and highly recommend them!

by James, Ajax on Twintech Heating and Cooling

Clean, Fast and Efficient Work. Between all the quotes I received Twintech was a few dollars less and offered the best warranty.

by garysumnec360, Whitby on Twintech Heating and Cooling

They did an excellent job. Everything was very well explained. At the end of the job everything was very well cleaned up.

by Glade, Pickering on Twintech Heating and Cooling

Twintech offered me a competitive price but more importantly great sales and installation service. They did everything with attention to detail and quality workmanship that is hard to find in this day and age. Dave who first game to visit me answered most of my questions and probed about my needs. For the technical/install questions he was unable to answer he quickly had Greg and Grant the owners answer for me. They did not cut corners on the installation or do anything to simply save time. They stayed into the early evening to complete the job and removed all my old components and even fixed up mistakes other workers ahd made in the past. I would highly recommend them and use them again if the need arises in the future. If you are looking for service or new equipment I would highly recommend Twintech be on your list of Heating companies to get a quote from and ask your questions to.

by Anne of Major Oaks in Pickering on Twintech Heating and Cooling

The company epitomizes high quality service: from the initial client interaction with Dave to the installation and follow up with the technical team. One of the key features I look for is the ability of a technical person to talk to and not talk down to the customer when responding to questions and I had quite a few, all of which were very professionally addressed. I was also quite impressed with the follow up service, promptness, the obvious competence of the team who left no stone un-turned to ensure I was a satisfied customer. Thank you guys.

by Aaron on Twintech Heating and Cooling

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

by Linda on Twintech Heating and Cooling

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

by Robert Mizuno on Twintech Heating and Cooling

We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!

by Ruth on Twintech Heating and Cooling

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
