The evolution of HVAC maintenance practices in Greater Montreal businesses
As the pandemic has gradually come to an end, businesses across Greater Montreal, from Montréal to Laval, including the South Shore and North Shore, have completely rethought how they manage indoor air quality. At AirGreen, we’ve seen a significant shift in demand for deep cleaning services of heating, ventilation and air conditioning (HVAC) systems. These new habits are not just temporary adjustments: they reflect a strong and lasting commitment to maintaining a healthy, efficient, and energy-saving indoor environment in all types of buildings — whether offices, retail spaces, or industrial environments.
A lasting mindset shift in HVAC maintenance
During the pandemic, awareness around indoor air quality reached unprecedented levels. Today, that level of attention has become the new standard. Businesses now understand that clean HVAC systems are critical not only for preventing the spread of viruses, but also for optimizing energy performance and extending the lifespan of their equipment. It’s within this context that five major habits have become firmly rooted in HVAC maintenance routines.
1. Scheduled HVAC maintenance replaces reactive interventions
Previously, many businesses would only call a professional once a problem occurred: reduced efficiency, strange odors, or excessive noise. Now, preventive HVAC maintenance contracts are becoming the norm.
-
At AirGreen, we’ve introduced customized service packages for commercial buildings across Montréal, Laval, Longueuil, and both the North and South Shores.
-
These plans include seasonal inspections, filter cleaning, coil washing, duct maintenance, indoor unit cleaning, and air exchanger upkeep.
The result: systems run more smoothly, consume less energy, and avoid costly breakdowns.
2. Systematic disinfection of sensitive components
Virucidal disinfection of air exchangers, supply vents, wall-mounted heat pumps and central units is now a standard part of our service. Our teams use approved products to eliminate:
-
Bacteria,
-
Mold,
-
Viruses on internal HVAC surfaces.
Businesses in the greater metropolitan area demand full transparency: we provide a report after each cleaning service, clearly documenting the hygiene measures applied.
3. Deep cleaning of ventilation ducts: now a top priority
Once neglected, duct cleaning is now a must for property managers. Some of our recent projects include:
-
A full duct network cleaning in a daycare in Brossard,
-
Duct sanitation in an office building in Laval-des-Rapides,
-
Disinfection of air ducts in a medical clinic in Rosemère.
Why? Because dirty ducts accumulate dust, allergens, mold, and fine particles, which are then circulated throughout the building.
4. Deep cleaning of commercial wall-mounted heat pumps: surging demand
Wall-mounted units, commonly used in small businesses, retail spaces, restaurants, were often forgotten in regular maintenance routines. Today, our clients understand that just cleaning the filter is far from enough. We perform:
-
A full dismantling of the casing,
-
High-pressure washing of the indoor unit,
-
Antibacterial disinfection of the coils,
-
Drain checks to prevent stagnant water buildup.
We recently delivered this service in several locations of a fast-food chain in Longueuil. The result: improved efficiency, reduced electricity use, and healthier air for employees.
5. Increased indoor air quality (IAQ) monitoring
Continuous indoor air quality monitoring is becoming increasingly common. Many businesses have hired us to install sensors that measure:
-
CO₂ levels,
-
Relative humidity,
-
Fine particulate matter (PM2.5),
-
Volatile organic compounds (VOCs).
This data allows for real-time HVAC adjustments to ensure optimal comfort. In an administrative building in downtown Montréal, AirGreen connected the ventilation system to a digital dashboard displaying live air quality in each area.
Client testimonial: a successful transformation in Laval
The owner of a gym in Laval contacted AirGreen after multiple complaints about stale air. Our inspection revealed massive mold buildup in the ducts, and a wall-mounted heat pump that hadn’t been cleaned since its installation. We proceeded with:
-
Complete duct cleaning and disinfection,
-
In-depth cleaning of a 24,000 BTU wall-mounted heat pump,
-
Installation of HEPA filters in the return vents.
A few days later, the gym’s attendance had surged. According to the owner: “Our members can feel the difference instantly. The air is so much cleaner. Thank you, AirGreen.”
Why these new habits are here to stay
Businesses no longer see HVAC cleaning as an expense, but as a strategic investment:
-
Increased productivity thanks to better air quality,
-
Reduced energy costs,
-
Protection of HVAC equipment,
-
Compliance with health standards in the event of an inspection.

Practical advice for businesses in Greater Montreal
Here are some simple but essential recommendations:
-
Schedule maintenance at least twice per year,
-
Avoid companies offering “quick cleanings” in under 30 minutes: proper cleaning takes time,
-
Request a detailed post-service report,
-
Incorporate HVAC operations into your occupational health and safety plan,
-
Educate your staff about the importance of a healthy environment.
