The invisible comfort that shapes guest experience and boosts the reputation of high-end hotels
In Montréal, competition among luxury hotels is no longer just about interior design or quality of service. Thermal comfort — quiet, constant, and perfectly balanced — is now a decisive factor in the guest experience. A single degree too much or a misplaced draft can negatively affect a stay. And today, those invisible details quickly become visible guest reviews, directly impacting online reputation.
At AirGreen, we know that HVAC installation in a luxury hotel leaves no room for improvisation. With our proven expertise in commercial air conditioning in Montréal, we help hotel establishments deliver flawless thermal comfort while respecting architectural, energy, and aesthetic constraints of their buildings.
Case study: modernizing the cooling system of a 5-star hotel in Old Montréal
Recently, we were hired by a boutique 5-star hotel located in a historic building in Old Montréal. This exceptional venue, hosting a demanding international clientele, faced persistent issues: recurring complaints about overly warm rooms, mechanical noise at night, and uncontrolled temperature variations.
Technical assessment and project requirements
After a complete analysis of the existing installations, our technicians identified several major challenges:
-
Dated central cooling system — noisy and inefficient
-
Uneven air distribution in certain high-end suites
-
No individual room control
-
Heritage regulations prohibiting any visible modification to the building exterior
Given these requirements, we designed a tailor-made solution to ensure performance, discretion, and smart connectivity.
Selected technology: wall-mounted Fujitsu KZAH R-32 air conditioner
To ensure optimal comfort without compromising the space’s aesthetic, we recommended the installation of a Fujitsu KZAH R-32 wall-mounted system, discreet, quiet, and extremely energy-efficient.
Technical features of the Fujitsu KZAH:
-
9,000 to 18,000 BTU depending on suite size
-
R-32 refrigerant with low environmental impact
-
Reduced noise level at 19 dB, ideal for a silent bedroom
-
Individual control via wall-mounted remote or mobile app
-
Compatible with LogisVert Commercial subsidies for energy efficiency projects in Montréal
These units were integrated into the rooms without altering the original design, while delivering constant thermal performance year-round.

-
91% decrease in temperature-related complaints
-
1.2-point improvement in comfort-related review scores on online platforms
-
Stabilized energy consumption, despite higher occupancy
