Furnace Noises and What They Mean

Has your furnace ever made a strange noise? There could be several reasons why your furnace is making noises. If you hear a whistling noise coming from your return air duct, that could be because of a dirty air filter. If your furnace is experiencing vibrations, squealing, and grinding noises, this can be a sign of a motor bearing issue. If popping or banging noises are coming from your furnace, this may be a sign of high heat rise.
Heat rise can lead to cracks and expansion within the heat exchangers, which can lead to a leak of CO in your home. If you are experiencing any of these furnace-related issues, make sure to call a technician to source and fix the problem.
Another potential cause of strange noises is running your furnace without a filter. Air filters prevent dust, hair, and lint from building up in the evaporator coil. A dirty coil restricts airflow in the system and can also lead to high heat rise if you’re not regularly cleaning it.
Often when the furnace fan begins to make noise, it’s because dirt has built up around the blower wheels. These wheels will need to be removed and cleaned to prevent overheating, and if left unattended, this could lead to the fan breaking down. Sometimes, selecting the wrong furnace fan speed can also be the source of strange noises.
It’s best practice to schedule a regular maintenance routine of your furnace to stop strange noises and ensure it is running smoothly.

Great service and great people to deal with, from sales to installer. I highly recommend this company.
Twintech replaced our aging furnace and air conditioner recently. I highly recommend this company. Their quote was competitive, they were on time and respectful of our home and extremely professional. From the salesman to the installers and the owner who followed up afterward to ensure we were satisfied, we are very pleased with the service. We are looking forward to working with this company for all of our HVAC needs for the years to come. Excellent workmanship and service!
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.

We had a great experience. The guys who installed our a/c did a nice job. Cleaned up.
excellent crew, fast and efficient! Would call them again when I need a new furnace.
Professional, courteous and efficient, dont need to say more than that! Use them you will not regret it.
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!

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.
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!
Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.
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!
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!
