Better maintenance for better cooling: essential strategies for building managers in Montréal
In Montréal, where summers can be humid and scorching, air conditioning system maintenance in residential, commercial, and institutional buildings is a critical issue. For building managers, HVAC performance isn’t just about comfort—it directly impacts equipment longevity, energy consumption, and occupant satisfaction. At AirGreen, we support building managers across Montréal, Laval, Longueuil, the North Shore, and the South Shore with tailored, professional air conditioning maintenance services. Here are five practical tips to maximize the efficiency and reliability of your HVAC systems.
Understanding the key role of preventive maintenance
Why regular maintenance is non-negotiable
A poorly maintained wall-mounted or central air conditioner leads to performance loss, higher electricity bills, and faster component wear. In multi-unit buildings or office towers, this neglect can result in collective system failures and damage the manager’s reputation.
At AirGreen, we recommend a full HVAC maintenance at least once a year, ideally in the spring, before the peak summer heat. Our team inspects filters, coils, condensate drains, thermostats, refrigerant pressure levels, and performs a thorough cleaning of all units.
Real case: preventive maintenance in a building in Outremont
Last April, we were hired to maintain 28 Gree wall-mounted heat pumps in a residential complex in Outremont. Several units were underperforming. After inspection, we removed large amounts of dust and mold that were clogging the evaporators. The result: more than a 20% improvement in energy performance and a significant drop in tenant complaints.
Implementing a structured maintenance schedule
Planning means prevention
Too often, HVAC maintenance is done reactively, only after a failure occurs. Yet, a rigorous maintenance schedule helps avoid costly emergencies. We recommend setting up an annual maintenance calendar that accounts for:
-
The type of equipment (central air conditioner, wall-mounted heat pump, multi-zone system, etc.)
-
The equipment’s age
-
Occupancy specifics (residential, commercial, extended operating hours)
Our solution: the AirGreen Pro program
We offer building managers a customized maintenance program that includes scheduled visits, technical reports, targeted recommendations, and priority service in case of breakdowns. This program is already in use at several senior residences in Laval and Longueuil.
Monitoring indoor air quality
A health and regulatory concern
A dirty HVAC system can become a source of contaminants: mold, allergens, bacteria. For building managers in Montréal, indoor air quality is a regulated issue, especially in commercial and institutional environments.
We regularly conduct air quality testing and disinfect air conditioning units with approved products that are safe for occupants. In Lachine, for example, at a 12-unit office complex, our intervention detected mold spores in the ductwork. After treatment, the air quality index improved from 62 to 92.
Training your in-house maintenance staff
Involve your team for better follow-up
Too often, on-site custodians or technicians lack the training to spot early signs of malfunction. We offer technical training sessions so your staff can:
-
Detect warning signs (unusual noises, leaks, reduced airflow)
-
Properly clean filters between professional visits
-
Quickly identify maintenance or repair needs
This educational partnership is already in place at several condo buildings on the South Shore, with real results in reducing emergency interventions.
Evaluating performance and planning replacements
Knowing when to replace instead of repair
Even with excellent maintenance, an aging air conditioning system will eventually lose efficiency. Generally, after 12–15 years, it’s more cost-effective to invest in a high-efficiency replacement.
We conduct thermal audits and performance analyses to guide our clients toward the best options. In Saint-Eustache, a building manager replaced 10 old units with Fujitsu KZAH R-32 wall-mounted heat pumps, subsidized by Hydro-Québec for $1,704. Annual electricity savings exceeded 18%.
