Sound Blankets will not completely eliminate all of the noise from your air conditioner. They are designed as a cost-effective solution as compared to moving or replacing your air conditioner. In general terms you should expect the noise level to drop by 30% to 50%.
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.
Common causes of air conditioner noise include loose parts, dirty filters, improperly mounted units, debris around the unit, and bent or damaged fins. You can fix most noises by tightening screws and bolts, cleaning or replacing filters, securing unit mounts, clearing debris, and straightening fins.
Air filter clogged with dust can cause wind noises from the indoor unit. Please make sure that the air inlet is not obstructed by any object . ▶ Air filter clogged with dust can cause wind noises from the indoor unit.
Soundproofing Products to Use for Reducing AC Noise
MLV sound barriers can be installed on or inside walls, around pipes or on air conditioner enclosures to help keep the home soundproof.
If your AC is making a lot of noise when you're trying to sleep, it can affect your ability to fall (and stay) asleep.
The most effective method to reduce fan noise is with an acoustical silencer. Silencers are designed specifically for noise control and are engineered for the subject fans airflow in CFM and the fans available pressure loss in the system, so as to not restrict its airflow.
Ductless 'mini split' systems like Mitsubishi home air conditioning systems are the quietest air conditioners on the market today.
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.

A sound blanket can reduce noise by up to 40%. These blankets wrap around the compressor (typically the loudest component), where the rubber and glass insulation absorbs the noise, trapping it inside the blanket.
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.
Common Causes of a Noisy Air Conditioner
Some of the most common issues include: Loose connections: Electrical connections, nuts, and bolts can all rattle around while an AC unit runs. Damaged blower motors: Air conditioner blower motors can struggle to spin correctly after years of wear and tear.
An AC squealing noise is usually caused by a worn-out fan belt or malfunctioning motor bearings. An HVAC technician can tighten or replace the belt or lubricate or replace the bearings, respectively.
Utilizing anti-vibration mounts or pads under the cooler can further reduce noise by absorbing vibrations before they can spread through the floor or furniture. Maintenance plays a vital role in keeping your air cooler running quietly.
If your air conditioner sounds like a jet engine, this is a sure sign that it is breaking down. The problem could be a faulty condenser fan, a failing compressor, or frozen evaporator coils.
Loose or Damaged Blower Components
Over time, the various components of your HVAC blower can loosen or sustain damage. Loose fan blades, motor mounts, or deteriorating belts can cause vibrations and rattling sounds.
