A Race Against Time to Cool a Care Facility in Montréal
When an intense heat wave hits Greater Montréal, its effects aren’t only felt on the streets or in apartments—it can seriously endanger the most vulnerable. In the middle of such an extreme emergency, AirGreen was called in to perform the urgent installation of a wall-mounted air conditioner in a CHSLD (long-term care facility) located in Montréal. A critical mission, carried out with efficiency, precision, and flawless organization, in the midst of a heatwave alert.
The Context: An Overheated Care Unit Facing Dangerous Temperatures
At the time of our intervention, outdoor temperatures were over 34°C, with humidity exceeding 75%. Inside the CHSLD, some rooms had already passed the 30°C threshold, posing a serious threat to elderly and medically fragile residents.
Facing an overloaded electrical system that prevented several portable AC units from operating, the facility’s management contacted us with a clear request: install a wall-mounted air conditioning system that would be reliable, quick to deploy, and capable of cooling multiple essential rooms from a single point.
Strategic Equipment Selection: Reliability and Immediate Efficiency
We recommended the Fujitsu KWL 18,000 BTU wall-mounted air conditioner, known for its consistent performance even during extreme heat and its ability to quickly cool large areas. This model met all the necessary criteria:
-
18,000 BTU capacity, covering up to 1,200 sq. ft.
-
Turbo cooling mode for rapid ambient temperature reduction
-
Inverter technology that reduces energy consumption and integrates with existing electrical systems
-
Ultra-quiet operation, respectful of the calm required in a CHSLD
-
Eligible for Hydro-Québec’s LogisVert program, depending on the building’s configuration
A High-Pressure Job: Technical Challenges and Precise Coordination
1. Limited Access and Delicate Working Conditions
The wall-mounted unit had to be installed in a wing of the building with restricted access, while also respecting health and safety regulations. Our technicians, fully equipped, worked in controlled conditions with masks, sterilized tools, and direct coordination with CHSLD management to avoid disrupting ongoing care.
2. Drilling Through Reinforced Insulated Walls
The facility’s exterior walls were made of composite insulated panels, making drilling more complex. We used a low-vibration diamond coring system to ensure a clean opening without affecting the structural integrity.
3. Rapid Commissioning and Real-Time Adjustments
The outdoor unit was installed on an anti-vibration base on the rooftop terrace, with sealed conduit routing running along the façade. Commissioning was completed within two hours of the final installation, with dynamic adjustments based on the actual thermal needs of the care unit.
Immediate Results: Temperature Drop, Widespread Relief
Within the first hour of operation, the target rooms experienced a temperature drop of over 5°C, bringing the ambient air to a comfortable 23 to 24°C, continuously. CHSLD staff quickly noticed a decrease in resident agitation, improved sleep quality, and a reduced risk of heat-related medical complications.
Testimonial from CHSLD Management: “AirGreen Delivered More Than Equipment—They Delivered a Solution”
The facility’s director, clearly relieved, shared this message:
“Your team showed rare professionalism. Less than 12 hours after our call, the unit was not only installed but already relieving our residents. You were essential partners in a critical situation.”

Best Practices to Prevent Heat Emergencies in Sensitive Environments
-
Schedule HVAC maintenance each spring before summer begins
-
Choose high-efficiency wall-mounted air conditioners over portable units
-
Request a thermal assessment of the most sensitive rooms
-
Plan for a backup system in case of electrical overload
-
Work with a reliable local HVAC partner like AirGreen who responds quickly
