Exceptional Repair of a COAIRE Ductless Heat Pump in Montréal

Breathing New Life into a COAIRE Heat Pump: A Montréal Success Story

When a customer in Montréal called us about their COAIRE ductless heat pump, they were convinced it was beyond repair. The machine, which had served faithfully for years, had started showing signs of wear and tear. With inconsistent performance and some unusual noises, the homeowner was ready to scrap it. Enter AirGreen, your trusted HVAC partner in Montréal, Laval, Longueuil, and beyond, determined to give this unit a second chance.

The Challenge: Is This Heat Pump Done For?

From the outside, the COAIRE unit showed visible signs of aging—dust, wear on the casing, and minor corrosion around the edges. Internally, the customer reported inconsistent airflow, diminished cooling efficiency, and occasional grinding noises. These symptoms pointed to a mix of mechanical and electrical issues, leaving the machine underperforming in Montréal's ever-changing climate.

The customer expressed doubt: could this aging unit still function, or was it time to invest in a replacement? At AirGreen, we don't just provide cookie-cutter solutions. We analyze every situation to offer our customers the best value for their money. In this case, we were confident we could restore the machine's performance and extend its lifespan.


Our Step-by-Step Repair Process

1. Detailed Diagnosis

Every repair starts with a thorough inspection. Our expert technician dismantled the unit to examine:

  • Internal components like the fan motor, refrigerant lines, and evaporator coils.
  • Electrical connections for signs of wear, shorts, or corrosion.
  • Drainage system to ensure there were no blockages causing internal leaks.

We discovered that the heat pump’s fan motor had become clogged with debris, while some electrical connections had loosened over time. Additionally, the refrigerant level was slightly low, which contributed to reduced cooling power.

2. Restoring Mechanical Components

The first order of business was cleaning and lubricating the fan motor. Years of accumulated dust had caused resistance, making the fan inefficient and noisy. After servicing the motor, we replaced a worn belt to restore smooth operation.

3. Electrical Repairs

Loose connections can be dangerous and reduce the efficiency of any heat pump. We tightened all connections, replaced a corroded relay, and tested the system to ensure consistent power flow.

4. Refrigerant Optimization

The refrigerant level was carefully adjusted to factory specifications. A properly charged refrigerant system is essential for optimal cooling and heating performance, especially during Montréal's humid summers and frigid winters.

5. Drainage System Maintenance

Lastly, we cleared the drainage line, which had begun to clog with dirt and debris. This simple step eliminated the risk of future leaks and ensured the system’s longevity.


The Outcome: A Heat Pump Reborn

After several hours of meticulous work, the COAIRE ductless heat pump was humming like new. The homeowner was amazed to see the transformation. The unit now delivers:

  • Improved airflow, thanks to the cleaned and restored fan motor.
  • Consistent cooling and heating, with optimal refrigerant levels.
  • Quieter operation, as all loose parts and debris were addressed.
  • Extended lifespan, giving the customer years of additional service.
