Ensuring optimal comfort in your commercial buildings during winter in Montréal, Laval, Longueuil, the North Shore or the South Shore is no small feat. When temperatures drop, a high-performing commercial heating system becomes a cornerstone of your operations. Yet many businesses overlook a critical point: preventive maintenance of their heating systems. At AirGreen, we know that the key to avoiding costly breakdowns, preserving energy efficiency, and extending the lifespan of your equipment lies in a rigorous winter preparation.
Why maintain your commercial heating system before winter?
A poorly maintained central heating system can quickly become a major issue—especially when temperatures plunge below zero. We've often been called in for emergency repairs in Montréal or Laval in the middle of January because a business skipped a simple seasonal check-up. The result: a central heat pump shutdown, unhappy employees, and a hefty bill. Winter maintenance is a strategic investment, not an unnecessary expense.
Risks of skipping maintenance:
-
Unexpected breakdowns during the coldest periods
-
Increased energy consumption and rising operational costs
-
Shortened lifespan of HVAC equipment
-
Thermal discomfort for staff and customers
-
Loss of productivity, especially in offices, retail spaces, or warehouses
What does proper winter maintenance for commercial heating include?
At AirGreen, our interventions are meticulously structured. Whether you have a central heat pump by FUJITSU, BOSCH, GOODMAN or GREE, we tailor each visit to the brand, model, and specific needs of your building. Here are the key steps of our service:
1. Complete component inspection
We check the condition of heat exchangers, air filters, motors, thermostats, electric heating elements, ductwork, and electrical connections. On a recent job in Longueuil, we detected an invisible leak in a main air duct. If left unnoticed, this issue would have caused significant heat loss.
2. Thorough cleaning
Dust, dirt, and debris can greatly reduce the efficiency of an HVAC system. We clean the coils, replace filters if necessary, and fully wash the units. On the South Shore, in a logistics warehouse in Brossard, a simple cleaning helped recover an additional 15% of performance from a 60,000 BTU central Goodman heat pump.
3. Refrigerant pressure check
An imbalanced refrigerant charge can cause overheating, overconsumption, or even compressor failure. Our certified technicians precisely check the levels to ensure everything runs within the manufacturer’s specifications—be it FUJITSU R-32, Bosch BIVA IDS Premium R-454B, or GOODMAN R-32.
4. Safety system inspection
We test all safety mechanisms related to heating: pressure switches, thermistors, circuit breakers, alarms, etc. This ensures your facility and staff remain protected at all times.
5. System optimization
We calibrate smart thermostats, reprogram defrost cycles, adjust fan speeds, and ensure the perfect balance between comfort and energy efficiency.
AirGreen case studies: Real-world examples in Montréal and on the North Shore
Montréal – Annual maintenance of a BOSCH central heat pump in an office building
In a 5-story administrative building downtown Montréal, we carried out a full preventive maintenance on a 36,000 BTU Bosch BOVA system. The client had noticed a slight performance drop mid-season. Our inspection revealed a clogged filter and a partially frozen outdoor coil. After cleaning and recalibration, the building’s energy usage dropped by 12% on the following bills.
North Shore – Preventing a major breakdown in a shopping plaza
In Blainville, on the North Shore, a central FUJITSU KZAH R-32 system served an 8-unit commercial complex. Winter maintenance by our team revealed an unusual noise coming from an axial fan. We immediately replaced the part before the cold season hit, successfully preventing a heating outage in the middle of February.
