A restful night’s sleep—free from disruptive noise and temperature fluctuations—is essential to our daily well-being. In Montreal, where summer nights can be stifling and uncomfortably warm, a quiet wall-mounted air conditioner is much more than a luxury: it’s a necessity for many households. At AirGreen, we’re often called in to install air conditioning systems that deliver high energy performance, reliability, and most importantly, ultra-quiet operation, ensuring optimal comfort throughout the night.
Why is silence so important in a bedroom with air conditioning?
A noisy air conditioning unit can easily disrupt your natural sleep cycle, even at low volume. Vibrations, motor hums, or poorly directed airflow create a disruptive environment—especially in residential areas of Montreal, Laval, and Longueuil, where urban density amplifies surrounding noise.
That’s why we recommend—and frequently install—highly silent models like the Fujitsu KZAH R-32 or the Gree Sapphire, known for their advanced sound-reduction technology. These systems, equipped with inverter compressors and variable-speed fans, often reach noise levels as low as 19 dB, barely louder than a whisper or rustling leaves.
Case study: Installation of a quiet wall-mounted air conditioner in the Rosemont district of Montreal
As part of a recent project in Rosemont–La Petite-Patrie, our technicians were called by a young family concerned about their sleep quality—especially for their newborn. They were looking for a quiet, reliable, and energy-efficient wall-mounted air conditioning solution suited to a 14x12 foot closed bedroom.
We recommended the installation of a Gree Sapphire 12,000 BTU wall-mounted heat pump, a model well-known for its extreme quietness in night mode, its smart dehumidification feature, and low electricity consumption. This unit uses R-32 refrigerant, known for its low environmental impact and high energy efficiency.
Technical details of the installation
-
Location: Rosemont, Montreal
-
Model installed: Gree Sapphire 12,000 BTU
-
Noise level: 19 dB on minimum speed
-
Refrigerant: R-32
-
Installation time: 4 hours

Thanks to our expertise, we completed a clean wall installation with discreet routing of the refrigerant lines using an aesthetic cover that matched the exterior. The client also opted for our annual HVAC maintenance service, ensuring the unit's long-term performance.
Why we prefer air conditioners with inverter technology
In all our wall-mounted air conditioning projects in Montreal, Laval, the South Shore, and the North Shore, we prioritize units equipped with inverter technology, which allows the compressor to adjust its speed based on demand. The result: a stable temperature throughout the night, without the abrupt ON/OFF cycles that cause noise.
This prevents sleep disruptions caused by temperature swings or sudden compressor starts. In addition to being more energy-efficient, these systems can lead to up to 40% savings on electricity bills.
Our criteria for the ideal wall-mounted air conditioner for nighttime use
At AirGreen, we follow strict criteria when selecting and installing HVAC systems for bedrooms:
-
Absolute silence (<20 dB in night mode)
-
Directional airflow to avoid drafts over the sleeper
-
Presence or motion detection sensors to adjust temperature automatically
-
Smart Wi-Fi controls for pre-sleep scheduling
-
Advanced air filtration technology for clean air throughout the night
Practical tips to maximize nighttime comfort with your AC
-
Avoid directing airflow straight at the bed: it can cause discomfort or sore throats.
-
Use the built-in "sleep" mode: it gradually adjusts the temperature to promote sleep.
-
Maintain your unit regularly: clogged filters reduce airflow and increase noise.
-
Install thermal curtains: they reduce heat exchange and improve your AC’s efficiency.
