Repair of a COAIRE Wall-Mounted Heat Pump in Laval

Breathing New Life into a Trusted Heat Pump

At AirGreen, we understand the importance of maintaining your HVAC systems for maximum efficiency and longevity. Recently, we embarked on a service call in the heart of Laval, where we faced an interesting challenge: repairing a COAIRE wall-mounted heat pump that the homeowner believed was beyond saving. By the time we finished, the system was not only operational but performing as if it had just been installed. Here’s the story of how we turned a seemingly dire situation into a moment of triumph.

The Call for Help: A Machine on the Brink

The homeowner, like many of our customers, depended on their heat pump for year-round comfort. However, after years of service, the unit had started to show its age—poor cooling, inconsistent heating, and strange noises hinted at its deteriorating condition. The client reached out to us, convinced that a full replacement was inevitable.

When we arrived, the COAIRE unit greeted us with signs of wear and tear. It’s a durable and efficient machine known for its reliability, but even the best systems need attention over time. We approached the project with one goal: to bring this unit back to life, saving the customer from the expense of purchasing a new one.


The Inspection: Pinpointing the Problem

Our skilled technicians started with a thorough inspection. Every corner of the COAIRE heat pump was assessed, from the air filters to the refrigerant lines and electrical components. We discovered several issues:

  • Blocked Air Filters: Years of dust and debris had clogged the filters, drastically reducing airflow.
  • Low Refrigerant Levels: A small leak in the system had caused the refrigerant levels to drop, compromising its cooling power.
  • Worn-Out Fan Motor: The motor responsible for circulating air had become noisy and inefficient.
  • Dirty Evaporator Coils: Dust and grime had accumulated on the coils, impairing heat transfer and overall efficiency.

Despite these challenges, we knew the unit could still be restored.


The Repair: Reviving a Trusted Companion

Step 1: Deep Cleaning

We began by meticulously cleaning the indoor and outdoor components. The filters were replaced, and the evaporator coils were scrubbed to remove years of buildup. This alone drastically improved the airflow and efficiency of the system.

Step 2: Fixing the Refrigerant Leak

Using advanced detection tools, we pinpointed the source of the refrigerant leak. Once sealed, we recharged the system with the appropriate amount of refrigerant, restoring its cooling capabilities.

Step 3: Replacing the Fan Motor

The worn-out motor was swapped for a new, high-efficiency replacement. This upgrade ensured quieter operation and better air circulation throughout the home.

Step 4: Testing and Optimization

After the repairs, we ran a series of performance tests. The COAIRE unit now delivered consistent temperatures, ran smoothly, and showed improved energy efficiency. It was ready to serve the customer for many more years.


Why Repair Over Replacement?

Many homeowners assume that replacing a malfunctioning heat pump is the only option. However, this service call demonstrates the value of expert repairs. By choosing to repair their COAIRE unit, the customer:

  • Saved Money: Repairs cost significantly less than installing a new unit.
  • Reduced Waste: Extending the lifespan of existing equipment is environmentally friendly.
  • Maintained Comfort: The quick turnaround ensured minimal disruption to the household.

The Outcome: A Happy Customer

When we presented the results to the homeowner, they were thrilled. Their “scrap” heat pump had been transformed into a reliable system once again. We also provided tips for regular maintenance to keep the unit in peak condition, including scheduling professional cleanings and inspections every 12 to 18 months.
