The hospital environment imposes extremely demanding HVAC requirements. At the crossroads of health, technology, and human well-being, precise control of temperature and humidity becomes an absolute necessity. At AirGreen, we have developed a specific and often discreet expertise in this delicate field by offering tailor-made commercial air conditioning solutions for hospitals and healthcare centers in Montréal, Laval, Longueuil, as well as on the North Shore and South Shore.
Why hospital air conditioning is a unique challenge
HVAC systems in hospitals can’t just maintain a comfortable temperature. They must:
-
Guarantee impeccable air quality (filtration, purification, air exchange),
-
Maintain stable relative humidity (generally between 40% and 60%),
-
Operate 24/7 without interruption,
-
Ensure precise thermal zoning, especially between operating rooms, intensive care units, laboratories, and patient rooms,
-
Reduce the risks of bacterial or viral spread through controlled ventilation.
That’s what deeply sets apart a residential air conditioning system from a hospital HVAC installation.
A discreet yet essential expertise by AirGreen
Over the years, we have supported several healthcare facilities across Greater Montréal, including sensitive public institutions and highly specialized private clinics.
Our approach is based on three essential pillars:
1. Comprehensive thermodynamic assessment of the facility
Before making any technical proposal, our HVAC engineers carry out:
-
An in-depth analysis of volumes and airflows,
-
A thermal mapping of critical areas,
-
Identification of cross-contamination risks related to ventilation.
This allows us to design a hyper-precise air conditioning plan, in full compliance with current health standards (CSA Z317, ASHRAE 170).
2. Installation of advanced commercial systems
We prioritize systems designed for high-demand environments. Here are some brands and configurations we regularly install:
-
Trane CGAM Series with centralized digital control and air-cooled condensing,
-
Lennox L Series™, offering ultra-quiet operation ideal for rest areas,
-
Bosch BOVA with R-454b refrigerant, highly valued for its energy efficiency and low environmental impact,
-
Arcoaire and ACD multi-zone systems, perfect for converting clinics or expansion projects.
Each installation includes a duct network with integrated HEPA filtration, temperature and humidity sensors in each zone, and often a real-time connected monitoring system.
3. Continuous maintenance and adjustment
We also provide:
-
Specialized HVAC maintenance contracts for hospital environments,
-
Performance audits for energy efficiency,
-
Training for the facility’s maintenance staff for basic operations (without compromising sterile zones),
-
24/7 availability for emergency service calls.
Case study: Critical care unit in Longueuil
In 2024, we were hired to upgrade the air conditioning system of an operating room and critical care unit in a Longueuil clinic. The main challenges were:
-
Unstable humidity causing condensation inside existing ducts,
-
Temperature variations of +/- 3°C depending on the time of day,
-
A lack of precise zoning for the operating rooms.
We proposed and installed a Bosch BOVA multi-zone system, with independent control for each room, CO₂ sensors, and a connected digital regulation system integrated into the building management system. The result: thermal stability within +/- 0.5°C, a 34% improvement in measured air quality, and silent operation—essential in medical environments.
The importance of humidity control in healthcare
Humidity’s role is often underestimated. Yet:
-
Air that’s too dry increases the risk of respiratory infections,
-
Excessive humidity promotes bacterial and fungal growth,
-
Humidity affects the accuracy of sensitive medical equipment.
At AirGreen, we systematically install integrated humidifiers and dehumidifiers, tailored to each room’s profile. We notably use Nortec electrode steam humidifiers for their reliability and ease of maintenance.
Practical tips for hospital and clinic facility managers
-
Schedule a complete annual checkup of the HVAC system with a healthcare-specific expert.
-
Opt for preventive maintenance contracts over 5 or 10 years, with rapid replacement clauses.
-
Integrate your air conditioning systems into a centralized building management system (BMS) to boost responsiveness.
-
Ask your HVAC provider for automated monthly reports on thermal performance.
