The rise of connected air conditioners in the context of urban cybersecurity
In a transforming energy and digital landscape, air conditioning in Montréal is no longer just about thermal comfort. It is now a matter of cybersecurity, smart building management, and ensuring the continuity of essential services. This paradigm shift is affecting schools, daycares, municipal buildings, and private enterprises more and more.
Aware of these stakes, the municipal authorities in Montréal — as well as several boroughs on the North Shore and South Shore — have started to invest massively in connected air conditioners, focusing on secure, smart, efficient models that comply with government cybersecurity standards.
At AirGreen, we have recently participated in several projects to modernize HVAC systems in Montréal, replacing traditional air conditioners with connected and securely managed wall-mounted and central heat pumps.
Digital security and air conditioning: an increasingly stringent requirement in public tenders
Today, public and commercial tenders require air conditioning systems that comply with cybersecurity protocols. This includes:
-
Units capable of connecting to BMS (Building Management System) platforms
-
Encrypted data transmission between devices and servers
-
Secure remote access with connection logging
-
Certified and traceable software updates
Traditional air conditioners are not designed for these standards, so only certain models of connected heat pumps — such as Lennox central units, Bosch BOVA, or Midea EVOX — meet the required criteria.
Case study: HVAC replacement in a community center in Montreal
AirGreen was recently tasked by a community center in the Rosemont–La Petite-Patrie borough to replace six outdated wall-mounted air conditioners with secure, connected heat pumps.
System installed:
-
Brand: Midea EVOX G3
-
Type: Central heat pump with secure WiFi communication
-
Capacity: 3 tons
-
Refrigerant: Eco-friendly R-454B
-
Security features: TLS 1.2 encryption, secure web interface, compatibility with municipal servers
Installation process:
-
Complete audit of the building’s network connections
-
Replacement of old refrigerant piping and revision of ducts
-
Integration into the existing BMS system
-
Compliance check with the city’s IT team for cybersecurity standards
-
Commissioning and staff training
Immediate results: improved thermal comfort, digital security, and energy savings
Within the first few weeks, the building managers noted:
-
A 25% reduction in energy consumption
-
Real-time access to operational data from the heat pumps
-
Redundant power supply with alerts for failure or unauthorized connection attempts
-
Better control of humidity and temperature in sensitive areas
Why Montreal is making this technological choice now
Increasingly frequent extreme heat
Montréal is regularly affected by heatwave episodes, especially in densely populated neighborhoods. The demand for high-performance, rapidly deployable, and reliable air conditioning systems is now a top priority.
Growing number of cyberattacks targeting infrastructure
Several recent incidents across Canada have highlighted the vulnerability of connected HVAC systems. Hospitals, schools, and government buildings have been targeted by attacks that temporarily disabled their heating or cooling systems.
This context is why Montreal decided to standardize all technical equipment in public buildings, requiring devices that are:
-
Capable of resisting digital attacks
-
Remotely manageable with strong authentication
-
Compatible with segmented, secure networks
Available subsidies to accelerate the transition
Programs such as Hydro-Québec’s LogisVert and several municipal grants make it possible to fund the purchase and installation of smart air conditioners, particularly those using low-GWP refrigerants like R-32 or R-454B.
At AirGreen, we assist our clients in assembling subsidy applications, providing all necessary technical data and installation documentation.
