Boosting energy performance through targeted HVAC maintenance in a Laval business
At a time when energy efficiency is becoming a key strategic priority for many businesses, a simple HVAC cleaning can produce spectacular results. At AirGreen, we were recently contacted by a small manufacturing company in Laval facing an unusual spike in heating and cooling costs. What started as a routine service call turned into a powerful demonstration of the impact of professional HVAC maintenance: an immediate 30% savings on their energy bill.
A complete HVAC diagnostic to identify efficiency loss
This company, located in Laval’s industrial park, operates in a 6,000 sq. ft. building equipped with several wall-mounted air conditioning units and central ventilation systems. Despite having relatively modern equipment, the management team had noticed their energy costs steadily increasing over several months. That’s when they called our team to perform a full inspection and cleaning of their heating, ventilation, and air conditioning systems.
Our first step was to carry out a thermal and mechanical diagnostic of all equipment:
-
Performance analysis of the wall-mounted heat pumps and ventilation systems.
-
Ductwork inspection to detect dust buildup, industrial grease, and debris.
-
Checking filters, motors, evaporator coils, and condensers.
The diagnosis: clogged coils, saturated filters, dirty fans, and a significant accumulation of debris in the ventilation ducts. This lack of maintenance was directly affecting the thermal performance of the entire system.
The HVAC cleaning process performed by AirGreen in Laval
Our specialized team implemented a two-phase intervention, spread over two days to minimize disruption to production:
1. Deep cleaning of wall-mounted and central units
-
Disassembly and coil cleaning using high-pressure biodegradable solutions.
-
Degreasing and full wash of fans, motorized louvers, and casing.
-
Antimicrobial treatment of the drainage trays to eliminate fungal and bacterial contamination.
-
Filter replacement with high-efficiency MERV-13 rated models.
2. Servicing ductwork and mechanical ventilation
-
Industrial-grade duct vacuuming with high-speed rotary brushes.
-
Disinfection using certified agents that do not impact indoor air quality.
-
Calibration of airflow dampers and verification of static pressure throughout the network.
This complete HVAC cleaning in Laval restored optimal airflow performance and brought the heating and cooling systems back to their original efficiency levels.
Measured results: 30% reduction in monthly energy bill
Three weeks after our intervention, the operations manager shared a clear result with us: a 30% reduction in electricity consumption linked to HVAC, along with a noticeable improvement in thermal comfort across offices and production areas.
Here’s what the client experienced:
-
Fewer compressor start/stop cycles (less mechanical wear).
-
Improved indoor air quality, with airborne particles reduced by 67%.
-
Reduced noise levels from wall-mounted units (quieter after cleaning).
-
Better air distribution throughout the entire building.
Why HVAC maintenance can transform energy performance
Dirty HVAC components act as an invisible brake on system efficiency. When a system has to overcompensate to maintain a set temperature, it consumes more energy and wears out faster. That’s why we recommend all businesses in Laval, whether they use wall-mounted heat pumps, central systems, or ducted HVAC, to schedule preventive maintenance at least once a year.
At AirGreen, we tailor our services to:
-
The size of the building (residential or commercial).
-
The type of equipment installed: heat pumps from Gree, Fujitsu, Sharp, Trane, Bosch, and others.
-
The specific environment: industrial dust, grease, humidity, etc.
