Sleeping deeply, waking up refreshed, and staying alert throughout the day: that’s what every homeowner is looking for. Yet few realize just how much a good wall-mounted air conditioner, properly installed by a professional like AirGreen, can transform their nights. Clinical research confirms it: maintaining the right room temperature with a high-quality unit can significantly improve sleep quality. In this article, we explore five essential benefits your wall-mounted AC brings to your sleep—supported by serious studies, technical insights, and real-world examples from our field experience across Montréal, Laval, Longueuil, the North Shore and South Shore.
Perfect thermal regulation for deep sleep
Restorative sleep starts with the right bedroom temperature. According to a study published in the Journal of Physiological Anthropology, an optimal bedroom temperature between 16 and 19 degrees Celsius promotes deep sleep. Thanks to wall-mounted heat pump models like the Gree Lomo, Fujitsu KZAH R-32, and even the Sharp ZU1, we help our clients maintain this ideal temperature all night long.
At AirGreen, we recently completed an installation in Longueuil of a 12,000 BTU Gree Lomo wall-mounted air conditioner, where the homeowners suffered from heat-induced insomnia. After installation, they noticed a significant drop in nighttime awakenings and improved daytime focus.
Reduced humidity: the silent enemy of sleep
High humidity levels in the bedroom severely impact breathing and, consequently, sleep quality. The modern wall-mounted air conditioners we install, including brands like Bosch, Tosot, and Lennox, come with smart dehumidification features.
For example, we recently worked on a residence in Boisbriand, on the North Shore, where indoor humidity regularly exceeded 70% during the summer. Thanks to the installation of an 18,000 BTU Sharp ZU1, we stabilized the humidity level around 50%, providing a notable improvement in nighttime comfort for a family suffering from asthma.
Absolute silence for uninterrupted sleep
One of the most critical factors in a wall-mounted air conditioner is its noise level. Older models or poorly installed units can produce a constant mechanical hum that disrupts deep sleep phases.
At AirGreen, we prioritize ultra-quiet models like the Fujitsu KZAH R-32, which operates at under 23 decibels in night mode. That’s exactly what a young couple in Saint-Hubert was looking for—they could no longer tolerate the humming of their old unit. After the replacement, they finally sleep through the night, even during heatwaves.
Smart programming: tailor your comfort to your sleep cycle
The modern wall-mounted heat pumps we install offer advanced scheduling features. This allows users to personalize their nighttime comfort by setting time slots, gradually adjusting temperatures, or enabling nighttime eco modes.
We recently advised a customer in Ahuntsic, Montréal, who was experiencing night sweats between 2 a.m. and 4 a.m. By activating the gradual cooling timer on their 15,000 BTU Fujitsu KZAH R-32, they noticed an immediate improvement in sleep continuity.
Better air quality: an ally against allergy-related awakenings
Many wall-mounted air conditioners today come with advanced filtration systems that remove allergens, pollutants, and even certain bacteria. This is often overlooked, yet crucial for people with allergies or respiratory sensitivities.
A great example: an installation in Brossard for a client allergic to pollen. Her new Bosch BIVA IDS wall-mounted air conditioner, equipped with a high-density filter, significantly reduced her nighttime congestion and allergy symptoms.

Clinical study supports the benefits
A study conducted by the Sleep Research Center at the University of Tsukuba in Japan shows that optimal thermal control improves the total duration of REM sleep, which is essential for memory processing and emotional regulation.
Comparing subjects sleeping in rooms with programmable air conditioners versus those in non-air-conditioned rooms, researchers observed a 27% reduction in nighttime micro-awakenings. These findings strongly support the benefits of a properly installed wall-mounted air conditioner for better sleep.
