Most furnaces have the blower factory set to deliver proper airflow on a decent duct system. Having excessive noise is an indication that the ducts are already undersized (and or furnace oversized) and cutting the speed below factory will overheat the furnace.
If you add an adjustable baffle at the furnace it will basically cut down on the airflow to that room. You could also look at putting a 90 degree turn into the flexible duct to cut down on the velocity of the air and maybe dampen some of the sound from the unit.
Using this guide as a frame of reference, most homeowners seek out an HVAC system that is 60 dB or lower. The quietest HVAC systems fall between the range of 50 to 60 dB.
Quiet Comfort: Carrier furnaces offer peace and quiet by utilizing variable-speed blower motors and fully insulated cabinets. This means you can enjoy a warm home without hearing your furnace running in the background.
So make sure your purchasing decision of the best furnace for your family includes carefully consideration of the sound levels it will generate. In all Carrier furnaces, quiet is built right into every system.
With Trane systems, you can rest assured that our high-efficiency compressors and specially designed tonal envelopes provide low sound levels in both air conditioners and furnaces.
Quieter Operation
Two-stage furnaces are quieter than single-stage furnaces due to their slower operating speeds and ECMs. Single-stage furnaces produce loud noises when they turn on and off.
The duct silencers enable maintaining proper acoustic parameters in the rooms – even reducing noise in the rooms which require a high degree of acoustic comforts, such as e.g. sleeping rooms or reading rooms. The noise can be generated not only by the flow of air through the ducts.
The best fix for this structural noise is to decouple the furnace from the floor or walls. The best way to stop impact noise coming from your furnace closet is to isolate the furnace using rubber. We recommend placing your furnace directly on some rubber isolation pads or on a rubber isolation mat.
Goodman's units are famed for their quiet performance. However, if your furnace is installed near a high-traffic area of your home, you may want to curtail operational noise with this sound reduction kit.
One of the common causes of furnace noises is dirty burners. Loud boom or bang sounds coming from your heating unit indicate dirty burners.
Normal Furnace Noises
Sometimes there is a little bit of a pop or click as the furnace fires up, then the heating system settles into a dull hum as it runs. Think of it like the click you hear when you turn on the burner on a gas stove.
For example, a smaller duct system could contribute to less air circulating through your home. This means that your new furnace is noisier because the larger size of its components allows you to receive more airflow.
If you want to pin us down to a generalized answer it would be 15-20 years. That lifespan can be significantly shortened if the furnace doesn't receive regular maintenance, was improperly installed, or is a furnace that doesn't use top-of-the line materials.

Trane Central Air Conditioner Condenser Fan Motor
The condenser fan motor has bearings that can wear out over time. When the bearings are worn out, they make loud noise.
For example, the Lennox SLP98V Variable-Capacity Gas Furnace is at least 50 percent quieter than competitor's furnaces, making the SLP98V gas furnace the quietest furnace you can buy1. SilentComfort™ is achieved by utilizing variable-speed technology.
One of the easiest and most cost-effective solutions for reducing noise is to install a sound blanket to act as an air conditioner noise barrier. You can check with your AC unit's manufacturer for a blanket size that will fit your unit, or you can purchase a universal sound blanket.
Today's furnaces are not only more efficient and safer but also significantly quieter. Central to this development is their focus on sound management.
Bryant furnaces usually don't make too much noise. Little noise is experienced just at the time of starting the furnace and at the time of it turning off.
There are a variety of problems that can cause your furnace to produce loud noises. Types of noises such as scraping, banging, whistling, and popping may be a sign of a loose part, cracked heat exchanger, or dirty gas burners.
