Five Tips to Soundproof Heating Ventilation and Air Conditioning Systems

Soundproof Heating Ventilation

The HVAC systems in homes and offices are essential to keep people comfortable. With as much comfort as these systems provide, a noisy HVAC system can disturb the home or office environment. Learning about different hvac sound barrier tips can cut down on a lot of unwanted sounds. Before learning how to minimize HVAC noise, it is essential to determine from where sounds are coming and what kind of soundproofing is required. This article enlists some critical tips for soundproof HVAC systems.

Install vibration mounts or an isolation pad below the unit

Vibrational energy from the furnace or AC unit may immediately reach the floor below, depending on where it is situated. This may also result in irritating vibrations and extraneous sounds that disrupt daily activities. These vibrations can be absorbed and kept from reaching the floor by using vibration mounts or an isolation pad. As a result, one of the main and most bothersome sources of HVAC noise will be much diminished.

Build and HVAC closet

If a homeowner wants to reduce the noise from the HVAC system, then he/she should create a closet to house the system. A closet is not only used to hide unsightly utilities but also to absorb vibrations and airborne sound waves before they escape the vicinity. To act as an effective hvac sound barrier, building the closet with dese walls and a heavy door is essential.

Wrap the HVAC system with sound-damping materials

The vibrations created by the HVAC system not only travel downward. If a person wants to achieve a high level of soundproofing, then it is best to wrap the HVAC unit with sound-damping materials. Usually, most sound-damping materials are easy to work it and don’t require anyone to install them. One needs to cut to size, peel the backing, and adhere to it wherever one wants.

Insulate the ducts

Wrapping ducts with an hvac sound barrier material can help reduce vibrations but won’t help absorb sound waves that travel inside them. If a homeowner wants to reduce those noises, it is better to utilize acoustic lining for the ductwork. Good ductwork insulation must be porous enough to absorb unwanted soundwaves and also be made of non-toxic or non-irritating materials.

Use duct silencers

One of the most efficient ways to control sounds inside the ductwork is to prevent sounds from entering in the first place. Duct silencers act as a sound baffle for ductwork, usually placed between the HVAC unit and the ductwork. This prevents the noises from making their way into the ducts and transferring into rooms.


Now that the basics of soundproofing the HVAC units are known, it’s time for homeowners to decide how to tackle their noise issues. Each HVAC system is unique, as also the home where it is placed, so make sure to ask the professionals if there are any doubts. These experts can detect noisy areas and specify the best soundproof products to deal with them.
