When Comfort Is Disrupted by Noise: Our Commitment to Absolute Quiet
At AirGreen, we know that thermal comfort should never come at the expense of peace and quiet in your living or working space. A noisy wall-mounted air conditioner can quickly turn a peaceful haven into a constant source of stress. This is a common issue we encounter during our service calls across Montréal, Laval, Longueuil, the North Shore, and the South Shore. Thanks to our experience, we’ve developed a series of technical and practical solutions to make your wall-mounted unit as discreet as a whisper.
Why Does a Wall-Mounted Air Conditioner Become Noisy?
A wall-mounted air conditioner can generate noise for several reasons, often linked to its installation, maintenance, or internal mechanical issues. During our service calls, we systematically assess:
-
The level of vibration from the indoor or outdoor unit.
-
The condition of the turbines, fans, and compressors.
-
The mounting brackets and the unit’s acoustic insulation.
-
The quality of maintenance (clogged filters, dust buildup, etc.).
Our technicians, specialized in HVAC, always take the time to identify the source of the noise in order to provide a lasting, customized solution.
Case Study: AirGreen Service Call in Laval for Abnormal Noise from a Fujitsu Wall-Mounted Unit
A residential client in Laval contacted us about a 12,000 BTU Fujitsu wall-mounted air conditioner installed two years ago by another contractor. In recent weeks, the unit had been emitting a low, intermittent noise that was disrupting the entire family’s sleep.
Our diagnosis:
-
The metal wall bracket had not been properly secured, amplifying vibrations.
-
The indoor fan was coated in dust, causing an imbalance during rotation.
-
The outdoor compressor was partially blocked by vegetation debris.
Our solution:
-
Leveled and reinforced the wall mount using vibration isolators.
-
Fully cleaned the fan and adjusted its axis.
-
Cleared the outdoor unit and added a specific acoustic insulator.
Result: over 70% noise reduction measured in decibels, and a satisfied customer who happily referred us to his neighbors.
Our Pro Tips for a Quieter Wall-Mounted Air Conditioner
1. Optimizing Installation with a Tailored Approach
The quality of the HVAC installation is crucial. At AirGreen, we use high-grade anti-vibration mounts and ensure that the indoor unit is installed on a stable load-bearing wall, with sufficient clearance. The outdoor unit is positioned on a solid base with rubber isolation pads to minimize resonance.
2. Choosing the Right Model, With the Right Capacity
An undersized unit constantly runs at full power, generating more noise. We recommend brands known for their quiet operation, such as Gree Sapphire, Sharp ZU1, or Fujitsu KZAH wall-mounted air conditioners, which integrate advanced noise reduction technologies. Their operating range is optimized to match thermal load without overworking.
3. Performing Regular HVAC Maintenance
A full HVAC maintenance check-up twice a year is essential to keep an air conditioner running efficiently and quietly. Our service includes:
-
Cleaning the air filters and evaporator.
-
Inspecting motor bearings.
-
Checking turbine balance.
-
Testing the unit’s soundproofing.
Our clients on the South Shore, especially in Brossard and Saint-Lambert, particularly appreciate our custom preventive maintenance program.
4. Using the Right Soundproofing Accessories
When noise persists despite all efforts, we recommend installing acoustic wall panels, or even soundproof enclosures for the outdoor unit. These solutions are especially useful in urban zones like Montréal, where noise can be amplified by residential density.
How New Technologies Help Reduce Noise
Modern wall-mounted air conditioners like the Bosch BIVA R-454B or the Goodman R-32 feature inverter compressors, which modulate their power based on demand. The result: fewer abrupt cycles, gradual startup, and therefore much less noise. At AirGreen, we always favor these technologies for their outstanding sound comfort.
