Repair Service of a COAIRE Ductless Heat Pump in Villeray–Saint-Michel–Parc-Extension

Breathing New Life into a “Lost Cause” Heat Pump

When we first arrived at the charming Villeray–Saint-Michel–Parc-Extension neighborhood for this service call, the customer greeted us with skepticism and a dash of hope. They were convinced their COAIRE ductless heat pump was destined for the scrapyard after years of faithful service. But at AirGreen, we thrive on challenges, and this situation was no exception. What unfolded next was a story of expertise, perseverance, and a bit of HVAC magic that saved the day — and the heat pump!


The Challenge: An Ailing COAIRE Heat Pump

The COAIRE ductless heat pump had seen better days. Over time, this robust machine had become a shadow of its former self, plagued by uneven performance and frequent breakdowns. Dust, wear and tear, and a misaligned fan had taken their toll. It was no wonder the customer was ready to give up. However, we knew that with the right expertise, this unit had the potential to deliver a few more solid years of reliable comfort.


The Diagnosis: Beyond the Surface

Our technician team began with a thorough inspection. Here’s what we found:

  • Clogged filters: Years of neglect had turned the filters into dust traps, severely restricting airflow.
  • Faulty capacitor: The heart of the system’s cooling power was struggling, causing erratic performance.
  • Refrigerant issues: A minor leak had reduced the refrigerant levels, further diminishing efficiency.
  • Fan misalignment: This was causing the heat pump to work harder than necessary, leading to wear and noise.

Each of these issues alone could render a heat pump ineffective, but together, they spelled trouble. Still, we weren’t ready to give up.


Our Approach: Precision Repairs and a Little Extra Care

Here’s how we tackled the repair with our signature AirGreen expertise:

1. Filter Cleaning and Replacement

We started with the basics. The filters were meticulously cleaned to restore proper airflow. Where necessary, we replaced parts with new, high-efficiency filters to enhance long-term performance.

2. Repairing the Capacitor

Replacing the capacitor was a delicate process. This small yet crucial component regulates the energy flow to the motor and compressor, ensuring smooth operation. Once installed, the heat pump immediately showed signs of improvement.

3. Addressing the Refrigerant Leak

Detecting and sealing the refrigerant leak was next. Our advanced leak detection tools pinpointed the exact location of the issue, and we sealed it with precision. After recharging the system with the appropriate refrigerant levels, the heat pump’s cooling power was back in full swing.

4. Realigning the Fan

The fan misalignment was corrected using specialized tools, reducing strain on the motor and eliminating the irritating noise that had been troubling the customer.

5. Deep System Cleaning

Finally, we performed a deep cleaning of the internal components, removing years of accumulated grime that had been silently choking the system.


The Result: A Heat Pump Reborn

Once we powered the unit back on, it was as if the COAIRE ductless heat pump had been given a second life. The cool air flowed evenly, the noise was gone, and the customer couldn’t hide their amazement. They had walked into this repair thinking it was a long shot, but they were walking away with a fully functional unit that would continue to serve their home for years to come.
