Reducing HVAC noise continues to be a growing demand in both commercial and industrial facilities via HVAC sound barrier solutions. There are numerous ways to implement this, but only some of them are truly effective.
HVAC systems are essential for maintaining comfortable indoor environments in commercial and industrial facilities. However, the noise generated by heating, ventilation, and air conditioning equipment can be a significant source of disturbance. Understanding how to reduce HVAC noise is crucial not only for compliance with Occupational Safety and Health Administration (OSHA) guidelines but also for enhancing productivity and well-being among occupants.
As stated by the Occupational Health and Safety Administration (OHSA), noise pollution has an adverse effect on workers’ health. Not only does it disrupt concentration and reduce productivity, but it can also lead to health issues.
Fortunately, you can choose one of several ways to fix this issue. The methods outlined below can effectively reduce the noise, but one particular solution can even solve the problem regardless of the degree of auditory disturbance.
Understanding the Sources of HVAC Noise
Before exploring solutions, it’s important to identify the common sources of HVAC noise:
- Air Handlers and Fans: These components can generate significant noise due to moving parts and airflow.
- Compressors: Often located outside, compressors can produce loud operational sounds.
- Ductwork: Vibrations and air movement through ducts can transmit noise throughout the building.
- Vents and Grilles: Airflow through vents can create whistling or whooshing sounds.
Ways to Reduce HVAC Noise
To achieve success in HVAC soundproofing, you can use either one of the following methods:
1. Use Sound Blankets and Barrier Walls
One of the most effective solutions for eliminating noise pollution is installing engineered HVAC sound barrier walls. Products like those offered by Sound Fighter Systems are designed specifically for HVAC noise reduction. These barriers not only mitigate sounds from HVAC units but can also block external noise from highways, railways, and industrial activities.
There are two main types of sound barriers:
- Sound-Absorbing Barriers: These barriers absorb sound waves, reducing the overall noise level.
- Sound-Reflecting Barriers: These deflect sound waves away from sensitive areas.
By choosing the appropriate type for your facility, you can control unwanted sounds from air handlers, compressors, and other mechanical equipment effectively.
2. Upgrade Your HVAC System
Modern HVAC systems are designed to be more energy-efficient and operate more quietly than older models. If your system is outdated, consider upgrading to a newer unit equipped with Variable Refrigerant Flow (VRF) technology. VRF systems adjust the refrigerant flow to match the building’s requirements, reducing the need for disruptive on-off cycling. This continuous operation at lower capacities results in significantly quieter performance.
3. Optimize Ductwork Design
Noise can travel through vents and ductwork, reaching occupied spaces and causing disturbances. To minimize this:
- Consult with HVAC professionals to redesign or reposition ductwork to reduce noise transmission.
- Install flexible duct connectors to isolate vibrations.
- Use larger ducts to reduce air velocity, which can lower noise levels.
- Implement acoustic lining or insulation within the ducts to dampen sound.
4. Wrap HVAC Ducts and Components
If redesigning ductwork isn’t feasible, wrapping ducts with specialized insulation materials can be an effective HVAC sound dampening technique. Acoustic insulation wraps reduce noise generated by air flowing through the ductwork and can be particularly useful for air handler noise reduction.
5. Rearrange Interior Spaces and Add Sound-Absorbing Materials
The interior design of a space can influence how sound is perceived. Hard surfaces like glass, metal, and concrete can reflect sound, amplifying HVAC noise. To counteract this:
- Incorporate soft furnishings such as carpets, curtains, and upholstered furniture.
- Add acoustic panels to walls and ceilings.
- Use indoor plants to absorb sound and improve aesthetics.
- Rearrange workstations to move them away from noisy equipment or ducts.
6. Regular Maintenance of HVAC Systems
Routine maintenance can prevent unnecessary noise caused by worn or malfunctioning components. Ensure that:
- Fans and motors are properly lubricated.
- Belts and bearings are in good condition.
- Loose panels or parts are secured.
- Filters are clean, reducing strain on the system.
7. Install Vibration Isolation Mounts
HVAC equipment can produce vibrations that transfer noise through building structures. Installing vibration isolation mounts or pads beneath equipment like air handlers and compressors can significantly reduce transmitted noise.

Excellent read! There are different reasons for vibration and loud noise from an HVAC unit. However, as previously discussed, various techniques for decreasing sound pollution are available. However, one of the most cost-effective and simple noise-reduction options is to use a sound blanket as a noise barrier. You may inquire with the manufacturer of your AC unit about blanket sizes that will cover your unit, or you can purchase a universal sound blanket.
