My Furnace Unit Makes Strange Noises
Posted On: October 14, 2024
If your furnace unit is making strange noises, it could indicate a variety of underlying issues that require attention. Here's a breakdown of common furnace sounds and what they might mean:
-
Banging or Popping: This could be caused by expanding and contracting air ducts or a dirty furnace burner. Dust and dirt can cause delayed ignition, leading to gas buildup that eventually ignites, creating a banging noise.
-
Squealing or Screeching: A high-pitched squeal is often a sign of a worn or slipping belt, or issues with the blower motor or bearings. If the motor is not lubricated properly, it can cause friction, resulting in this noise.
-
Rattling: Loose components such as panels, screws, or even the blower assembly can cause rattling. It might also indicate something more serious, like a cracked heat exchanger, which requires immediate attention to avoid carbon monoxide leaks.
-
Booming: A loud booming noise could be the result of delayed ignition due to dirty burners. This issue can create a small explosion when the gas ignites, which is both a noise and a potential safety hazard.
-
Humming: A low hum can be normal for furnaces, but if it becomes louder than usual, it could signal an electrical problem or issues with the blower fan.
-
Clicking: If you hear a clicking noise that doesn't stop after the furnace turns on, it could be a problem with the ignition system, such as a failing thermostat or a malfunctioning flame sensor.
If your furnace is making any of these noises, it's best to contact a professional HVAC technician to diagnose and fix the issue. Routine maintenance can also help prevent strange noises and keep your furnace running efficiently.

Very pleased with the installation of our new furnace and A/C unit. From quotation stage to the completion of the job Twintech was very professional.
Thank you for a job well done.

My old water heater quit on me. I called TwinTech. In less than 4 days, I had my new water heater installed and the old one taken away. The whole process was quick, easy, pleasant, and well done. This is the third time I've dealt with TwinTech and I've been satisfied each time.

I had them replace my furnace last year. When it came time for the air conditioner this year, I did not hesitate to call Twintech again. I will also have them perform regular maintenance on them.

We required a new HVAC replacement after running the old
system for 18 years.
Dave understood our requirements and gave us a quote that
covered all the necessary items.
Installation was fast and very tidy. Everything works as
it should. Our thanks to Greg, Mitch and others for their
excellent work. Recommend this family owned business to
anyone else, considering HVAC or other work.

I needed a new furnace and A/C to replace my 21 yr. old units, and went to the internet to view potential companies in May, I received 3 quotes,
and chose Twintech based on their salesman Dave who was very detailed and covered off everything on what Twintech was all about,
an extremely dedicated company with so many years of experience, and after reading the on line reviews I was sold on Twintech, who did not disappoint as the installation team were top notch with Greg leading,
I would highly recommend this company without any doubts, in my books they are first class all the way. Our new Amana furnace and A/C are working perfectly !
