Furnace Noise-Reducing Features & Technology

Is your noisy, and inefficient furnace struggling to keep up with your home heating demands? Interested in upgrading but conscious of furnace operation noise? Unsure of what to look for? If you’ve answered, yes to any of the above questions you are in the right place.

Many manufacturers are paying close attention to their design to provide Canadians with a quieter home heating solution.

In this article, we will take a look at how furnace type can play a direct role in the amount of operation noise you experience, popular noise reducing features seen across brands, and which innovative technologies brands are using to differentiate themselves from the competition.

How Does Furnace Type Affect Noise?

Canadian consumers can purchase the following types of furnaces: Single Stage, Two Stage, Variable Speed and Modulating propane and natural gas furnaces. The type of unit you purchase refers to the operation of the furnace.

Let’s take a look at how these different types of furnace operations stack up when it comes to furnace noise.

Modern single stage furnaces have come a long way and produce less furnace noise than the those from your childhood memories growing up. That said, they still function in an on/off operation which can result in a loud kick back as the furnace turns on in response to temperature changes in your home.

Two sage and modulating natural gas furnace operation with variable speed blowers offer Canadian consumers a quieter home heating solution. The variable speed blower assists with noise reduction, by running continuously at lower speeds and adjusting speed based on temperature changes within the home.

These subtle fluctuations in blower speed have the additional benefit of greater energy efficiency, in addition to quieter operation.

Many manufacturers also utilize the sound dampening benefits of insulation to their advantage, by lining the interior of the furnace cabinet with vibration and sound-dampening materials.

4 Common Furnace Features and How They Affect Noise

The features listed below help to lower the operating noise level of your furnace so that you can enjoy a quieter home heating experience.

  1. Insulated cabinet – reduces airflow between the unit, reducing sound production
  1. Two-stage and variable speed draft blowers
  1. ECM motor – runs continuously, adjusting its speed from low to high as needed and in response to temperature changes. With 5 speeds, the small incremental adjustments are slight and provide you with a quieter furnace operation. Since an ECM motor runs continuously, it eliminates the loud kickback which is often heard when a furnace turns on and off at the beginning of a heating cycle in traditional Single Stage heating systems.
  1. Soft-mounted blower and inducer motor – provide additional sound dampening

Noise-Reducing Technologies Used by Major Furnace Brands

The manufacturers listed below incorporate innovative technology and smart design to effectively minimize operational noise from their line up of high-efficiency natural gas furnaces.

  • Bryant – QuietTech™ innovative technology is designed to reduce the operational noise of your high-efficiency natural gas furnace.
  • Rheem – their patented heat exchanger design reduces airflow which acts as another noise reducing feature.
  • Carrier – their trademarked Comfort Fan™ technology gives consumers the ability to control the setting of their high-efficiency furnace fan with four different settings. By allowing the high-efficiency furnace to run continuously at lower speeds noise is reduced.
  • Lennox – Lennox’s SilentComfort™ technology works to minimize traditional furnace noise
  • Armstrong Air – the Quiet Combustion™Technology in their economy, mid-range and premium pricing model tiers to produce quieter furnace operation in all of their natural gas furnace models.
  • Luxaire – Silent Drive™Comfort System in their Acclimate™ Series LP9C model
  • American Standard – Vortica II™blower

If you’re like many consumers, after price, energy and warranty, furnace noise is at the top of your list when it comes to upgrading to a high-efficiency natural gas furnace. The competition has narrowed the playing field when it comes to furnace noise.
