Peaceful nights thanks to a quiet wall-mounted air conditioner: our guide to choosing the right model
In the comfort of a Montréal home, nothing beats a cool, quiet bedroom during hot summer nights. Choosing a wall-mounted air conditioner can make a big difference in your sleep quality. At AirGreen, we know that noise level is just as important as energy performance, especially when installing in a bedroom.
That’s why we’ve created a detailed comparison of five quiet wall-mounted air conditioners, ideal for bedrooms and installable in Montréal, Laval, Longueuil, the North Shore, and the South Shore. Our HVAC installation experts share their recommendations based on real-world installations, performance testing, and feedback from our clients.
Why choose a quiet wall-mounted air conditioner for a bedroom?
A wall-mounted air conditioner is a popular choice for its discreet profile, versatility, and easy installation. However, when it comes to a bedroom, the sound level becomes a critical factor. A noisy unit can disturb your sleep, especially if the compressor or fan runs constantly.
The models we’ve selected offer:
-
Operation under 23 dB, quieter than rustling leaves.
-
Inverter technology that reduces noise fluctuations.
-
Soft air diffusion, avoiding direct airflow over the bed.
