Rooftop HVAC Unit Repair in Montreal

Transforming a Neglected Rooftop Unit into Peak Efficiency

When we arrived at this Montreal rooftop, the HVAC unit was almost unrecognizable. Time, graffiti, and years of wear had left their mark on this vital piece of equipment. But where others might have seen decay, AirGreen saw an opportunity to breathe new life into a crucial HVAC system for a commercial property.

Assessing the Challenge: A Rooftop in Distress

This project began with a thorough inspection of the rooftop HVAC unit. The unit, originally installed years ago, had not been maintained consistently. Layers of grime and graffiti added to the wear, and the system's efficiency had dwindled significantly. Compounding the issue, nearby buildings generated additional heat and airflow disruption, which contributed to inconsistent temperature control inside the property.

Step-by-Step Restoration Process

To restore this system, our expert technicians followed a meticulous plan, ensuring that every component was inspected, cleaned, repaired, or replaced where necessary:

1. Systematic Cleaning

The first step involved removing debris and layers of accumulated grime. Using industrial-grade cleaning solutions and tools, we:

  • Cleared the air intake vents.
  • Cleaned internal components to remove dust buildup, improving air quality.
  • Scrubbed external surfaces to restore the unit's appearance and functionality.

2. Component Inspection and Replacement

Our team disassembled key sections of the unit to examine its mechanical and electrical components:

  • Compressors: Checked for overheating issues and refrigerant leaks.
  • Heat Exchangers: Ensured there was no rust or corrosion impacting efficiency.
  • Fan Motors: Lubricated moving parts and tested motor efficiency.
  • Filters: Replaced worn-out filters to ensure optimal air circulation.

3. Energy Efficiency Upgrades

This system was retrofitted with advanced components to enhance its energy performance:

  • High-efficiency compressors were installed to reduce energy consumption.
  • Upgraded controls allowed for smarter system monitoring and adjustment.
  • Insulation around ducts and pipes was improved to minimize thermal losses.

The Hidden Heroes: Advanced HVAC Technology

At AirGreen, we believe every repair is an opportunity to optimize performance. For this project, we incorporated:

  • Smart Thermostats: These enable real-time temperature monitoring and system control.
  • Energy Recovery Ventilators (ERVs): These were added to improve indoor air quality by balancing fresh air intake and stale air exhaust.
  • Variable Speed Fans: Installed to ensure smooth operation, minimizing noise and energy consumption.

Challenges on the Rooftop

Every repair job has its share of hurdles, and this project was no different:

  • Weather Conditions: Montreal’s unpredictable weather required careful scheduling and protective measures during the work.
  • Accessibility: The rooftop location demanded specialized equipment to safely transport tools and components.
  • Graffiti Removal: Restoring the unit’s appearance was as important as fixing its functionality, and we took extra care to ensure the exterior was graffiti-free by the end.

The Final Result: Functionality Meets Aesthetics

After days of dedicated work, the transformation was remarkable. The HVAC unit not only looked rejuvenated but was also operating at optimal efficiency. Here’s what the client gained:

  • Energy Savings: Enhanced components reduced electricity consumption by 20%.
  • Improved Comfort: Consistent indoor temperatures were restored, making the space more comfortable for occupants.
  • Long-Term Reliability: Preventive maintenance and upgrades ensure this unit will perform reliably for years to come.
