Commercial Rooftop HVAC Unit Repair: North Shore Excellence in Action

Revitalizing a Vital HVAC System for Optimal Performance

In the heart of Montreal's North Shore, we at AirGreen were called to tackle a challenging yet rewarding project: the repair and maintenance of a rooftop HVAC unit for one of our valued commercial clients. This wasn’t just a routine check-up—this was a full-scale mission to restore efficiency and ensure the long-term performance of a critical piece of HVAC infrastructure.

Our team specializes in commercial HVAC services across Montreal, Laval, Longueuil, and the surrounding areas, focusing on heating, ventilation, and air conditioning for commercial and industrial spaces. For this project, our expertise was put to the test on a rooftop unit that had seen better days. The images alone capture the unit’s condition before we began: signs of rust, dust accumulation, and exposure to the elements. The goal was clear—to breathe new life into this essential system.

Inspecting the Rooftop Unit: Assessing the State of Affairs

From the outset, our technicians noticed that the unit had visible wear and tear, a result of continuous exposure to harsh weather conditions on the North Shore. These rooftop units are built to withstand a lot, but without regular maintenance, even the best systems start to show signs of fatigue. The fan was coated with rust, while the coil fins had accumulated a layer of dirt and debris, which can severely impact airflow and overall performance.

1. Initial Inspection
   We started with a thorough inspection, checking the integrity of the main components, including the fan, coil, and compressor. This is critical for any rooftop repair job since the slightest oversight could lead to major system failures later on. Identifying problems early is essential to prevent costly repairs and ensure continuous operation, especially during peak seasons.

2. System Diagnostics
   Our team then ran detailed diagnostics to assess the electrical components, airflow, and temperature regulation. Each wire, control panel, and connection was inspected for wear, corrosion, or potential failure points. The diagnostics revealed a few minor issues in the control module and some electrical wiring that needed re-tightening and recalibration for optimal operation.

Restoring Efficiency: A Step-by-Step Repair and Maintenance Process

Our job wasn’t just about fixing what was broken; it was about optimizing the entire HVAC unit to extend its life and maximize efficiency.

1. Cleaning the Coil and Condenser

One of the most immediate issues was the dirt buildup on the coil and condenser. Dirt acts as an insulator, preventing heat from dissipating effectively, which forces the compressor to work harder. Using specialized cleaning solutions, we meticulously cleaned the fins and coils, restoring their ability to release heat and improving overall efficiency.

2. Replacing Rusted Components

The fan blade and motor were showing signs of rust. Rust can degrade the performance of a fan over time, leading to potential failure. We replaced the fan blade with a high-durability model designed to withstand harsh weather, ensuring it can perform optimally for years to come.

3. Electrical and Control System Calibration

The control panel was also in need of some attention. Minor recalibrations were made to optimize the thermostatic controls. Proper calibration of these controls allows for precise temperature management, reducing energy waste and ensuring consistent indoor comfort.

Extending the Life of the HVAC Unit: Our Preventive Approach

Preventive maintenance is key to ensuring the longevity and reliability of commercial HVAC units. In addition to the repairs, we also implemented a preventive maintenance schedule tailored to the unit’s needs and operating environment.

• Monthly Check-ups: Inspect and clean critical components such as the coils and fans to prevent dust and rust buildup.
• Quarterly Diagnostics: Run full diagnostics on the control systems, compressors, and electrical connections to catch issues early.
• Annual Tune-up: A comprehensive inspection and recalibration to align with seasonal demands and optimize performance.

Our client now has a robust maintenance plan in place to ensure their system stays operational and efficient throughout the year, even during Montreal’s intense winters and hot summers.
