Tailored HVAC solutions to reduce noise in commercial buildings
At AirGreen, we know that a comfortable commercial building isn’t just about temperature control. The noise level generated by heating and air conditioning equipment is a crucial factor that’s often overlooked. In environments like offices, retail stores, schools, clinics, or hotels, constant noise disturbance can negatively affect occupant well-being, productivity, and even the company’s reputation. That’s why we implement quiet commercial heat pump solutions that are perfectly suited to the realities of buildings in Montréal, Laval, Longueuil, the North Shore and the South Shore.
Why is HVAC equipment noise a real issue in commercial settings?
A noisy heating or cooling system can lead to:
-
Complaints from clients or employees
-
Loss of focus in work environments
-
Discomfort in rest or care areas (e.g., clinics or residences)
-
A decreased perception of quality in customer-facing spaces
At AirGreen, we approach every installation by first assessing the acceptable noise level for your specific environment, and then recommending heat pumps with decibel levels reduced to the absolute minimum.
How to choose a quiet commercial heat pump
Criterion 1: Sound level (dB)
The sound level of indoor units (wall-mounted head or cassette) or outdoor units (compressor) is measured in decibels (dB). A difference of just 3 dB can double the perceived noise. For sensitive environments, it’s essential to choose systems that operate below 50 dB, or even lower for wall units.
Criterion 2: Inverter technology
Models with inverter technology adjust output continuously, reducing noise associated with frequent stops and starts. This allows for a smoother, quieter operation, especially during off-peak hours.
Criterion 3: Strategic placement
Our HVAC experts in Montréal, Laval, Longueuil, the North Shore and South Shore optimize the placement of outdoor units (often the primary source of noise), taking into account shared walls, rest areas, windows, and public zones.
Case study: Office space in Laval – Installation of an ultra-quiet Fujitsu KRLH heat pump
In a professional office complex in Laval, tenants were complaining about the noise from the old outdoor unit located near the conference room. After an acoustic analysis, we recommended and installed a Fujitsu KRLH 36,000 BTU central heat pump, equipped with a compressor that offers extremely low sound levels (as low as 45 dB) in eco mode.
Challenges encountered:
-
Limited space to relocate the outdoor unit
-
Maintaining full office operations during installation
-
Preventing vibrations on the existing structure
AirGreen’s solutions:
-
Installation of a soundproofed concrete base
-
Use of anti-vibration connectors on all refrigerant lines
-
Smart programming with scheduled quiet operation modes
Result: a 65% reduction in noise-related complaints, increased acoustic comfort, and an energy efficiency rating above 21 SEER.
