We recommend using CelluZorbe to line the walls of your furnace closet. It is great at absorbing sound and is a very cost effective product. CelluZorbe is composed of mostly recycled materials (cellulose fibers) that are highly absorptive and safe to touch (unlike fiberglass).
Fix a vent by either tightening it down to the wall or by adding mass to change its resonance frequency or by using weather striping at the edges of the metal vent before putting it on the brackets so that the vibration from the air ducts are isolated from the vent.
You can reduce noise from an air conditioner by installing a sound blanket or sound curtain, choosing the location of the unit carefully, surrounding it with a fence, and adding sound absorbing or sound blocking material to the enclosure.
Dirty air filters or ducts: Over time, the dust and dirt buildup on your air filters and inside of your ducts makes it hard for your equipment to move air. It can also make the system noisier. The solution is to clean or replace your filter regularly and have your ducts cleaned if they start to impede airflow.
This blanket works by covering the air compressor, which is the noisiest part of an AC. The blanket absorbs the noise that the compressor makes. It is made of acoustic glass insulation and is responsible for sound waves. To reduce noise even better, the blanket has a heavy rubber barrier.
An HVAC duct silencer is specifically engineered to reduce airborne noise carried along ducts or produced by enclosures. You'll also find these silencers described as sound attenuators when they are used in industrial settings.
Fencing: Try putting a fence in front of or around the air conditioner, this creates a barrier for the sound and traps the sound's movement. You can use plywood to fence the air conditioner, or buy an air conditioner fence.
Dust, dirt, and debris around the coil fins, air ducts, and outdoor condenser unit are common causes of noise. Loose or misaligned parts like the fan blades or belt, lack of lubricant, blockage in the drain pipe, copper lines, or vents, and a malfunctioning thermostat can also lead to a noisy air conditioner.
ㆍQuiet mode ( ) makes the noise quieter during operating the indoor unit in the Heat mode. ㆍSince the air conditioner heats the room by taking heat energy from outdoor air, the heating capacity may decrease when outdoor temperature is extremely low.

Quiet a Loud Compressor
The loud and distracting racket created by normal A/C compressor noise bouncing off your exterior walls can make spending time outdoors less enjoyable. You can quiet the clamor by having a sound-insulating condenser blanket and/or vibration-dampening mounts installed.
It is best to place the Duct Silencer within 2 - 4 feet of the blower / ventilator for maximum noise reduction.
They take advantage of the principles of sound waves and the properties of materials to diffuse the noise. Sounds, just like light, are waves. When a sound wave hits an object, it's either absorbed, reflected, or transmitted. Duct fan silencers are designed to absorb these waves, significantly reducing the noise level.
Sound blankets do not impair airflow; in fact, they actually insulate the compressor and help the unit maintain a more consistent temperature, thereby prolonging the life span of the compressor's bearings. Further, sound blankets can reduce the noise coming from your air conditioner by 30 to 50 percent.
If your neighbour's AC keeps making excessive noise even after asking them to do something about it, you may bring the issue to the authorities and local court. It's best to get help from a real estate lawyer.
It describes common noise sources such as fans, compressors, pumps and ductwork. It then explains approaches to reduce noise such as using resilient hangers and mounts, lining ducts, sealing penetrations, and selecting quieter equipment.
An air conditioner blanket is a specialized type of blanket designed to keep you warm and comfortable when using an air conditioner. It is created from light, breathable cooling materials allowing you to sleep cooler without overheating or overcooling.
Sound Shield™ Sound Proof Acoustic Blankets are used in Industrial & Commercial Rooms where sound needs to be absorbed as well as reverberations and echoing stopped. These Acoustical Blankets with grommets are made from either a 1”, 2”, or even 4” Sound Absorbing Fiberglass based materials.
