Maximize the performance of your HVAC systems with regular and strategic maintenance
At AirGreen, experts in commercial air conditioning in Montréal, Laval, Longueuil, North Shore and South Shore, we understand just how essential well-maintained air conditioning is for consistent comfort, optimized energy use, and extending the life of your equipment. Too often, businesses underestimate the value of preventive maintenance, which can lead to costly breakdowns, efficiency loss, and premature system replacements.
Here are 5 proven professional tips we put into practice in the field to ensure the longevity and optimal performance of your commercial air conditioners.
Have your air filters inspected and cleaned regularly
Clogged air filters are one of the most common causes of reduced performance in air conditioning systems. They restrict airflow, force compressors to work harder, and increase electricity usage.
At AirGreen, during our maintenance visits to offices, stores or buildings across Montréal or the South Shore, we regularly find that filters haven’t been changed in months—sometimes years. This not only leads to poor indoor air quality but also shortens the motor's lifespan.
Our recommendation:
-
Check filters monthly during heavy-use seasons (June through September).
-
Call an AirGreen technician every 3 to 6 months for professional cleaning if your system covers large areas.
Schedule a complete HVAC maintenance twice a year
A preventive HVAC service call can save you thousands in the long run. These checkups help detect refrigerant leaks, verify electrical connections, test sensors, and ensure the unit is running at peak efficiency.
For example, we recently visited a building in Laval equipped with multiple central Fujitsu units, one of which was underperforming. After inspection, we found the evaporator coil was clogged and energy consumption was spiking. A deep cleaning alone helped cut the energy bill by 18% the following month.
Keep in mind:
-
Schedule visits with our team in the spring (before peak season) and in the fall to avoid surprises.
Don’t overlook outdoor units: they need your attention too
A significant number of emergency service calls we perform in Longueuil’s industrial parks or commercial zones on the North Shore involve outdoor units blocked by debris, pollen, or even snow.
These block heat dissipation, which can lead to compressor overheating and irreversible damage.
Our field-tested advice:
-
Keep a clearance of at least 60 cm (2 feet) around outdoor units.
-
Clean the fins with a soft brush or a gentle water spray.
-
On request, AirGreen installs seasonal protection systems tailored to our harsh Québec winters to prevent ice or leaf buildup.
Invest in a modern commercial heat pump
In many cases, recurring breakdowns or high power consumption are not due to poor maintenance but to obsolete equipment. A wall-mounted or central heat pump that’s over 12 years old may cost more to repair than to replace.
At a business on Jean-Talon Street in Montréal, we recently replaced an old system with a Gree Flexx R-32 central heat pump, eligible for the LogisVert program. The result: a 25% reduction in cooling costs within 6 months and significantly improved thermal comfort.
Why upgrade your system:
-
Better energy efficiency (SEER > 20)
-
Compliance with new environmental standards (R-32 or R-454B refrigerants)
-
Government grants available
Embrace smart management with programmable thermostats
Too many businesses leave their air conditioning running unnecessarily outside business hours. At AirGreen, we encourage our clients to install smart thermostats, remotely programmable, which optimize operating cycles based on actual building occupancy.
We recently equipped a training center in Brossard with a Bosch BOVA central system and multi-zone Wi-Fi thermostat. Along with 30% energy savings, the admin staff can now control temperatures remotely via mobile app.
Long-term advantages:
-
Fewer start/stop cycles → less wear and tear
-
Lower energy bills
-
Better adaptability to changing weather conditions
