Repair and Revival of a COAIRE Ductless Heat Pump in Rivière-des-Prairies–Pointe-aux-Trembles

Breathing New Life into a "Scrap" Machine: A Unique Repair Journey

When we received a call from a homeowner in Rivière-des-Prairies–Pointe-aux-Trembles about their COAIRE ductless heat pump, they were convinced the unit was beyond saving. “It’s scrap,” they told us. But at AirGreen, we love a good challenge—and we’re not ones to give up on a machine without a fight. What followed was an inspiring and meticulous repair job that not only saved the heat pump but also gave it a few more years of reliable performance.

The Problem: A Machine on Its Last Legs

When we arrived, the COAIRE ductless heat pump was in rough shape. The customer reported:

  • Erratic performance
  • A complete lack of heating or cooling functionality
  • Strange noises that suggested deeper mechanical issues

On inspection, we discovered several issues, including a worn-out fan motor, clogged filters, and a refrigerant leak. To many, this might have seemed like a lost cause, but we saw potential.


The COAIRE Heat Pump: A Closer Look

COAIRE ductless heat pumps are known for their efficient operation and compact design. This particular model was a 12,000 BTU unit, perfect for small to medium-sized spaces. Its strengths include:

  • Energy efficiency: Designed to save on utility bills while providing consistent comfort.
  • Compact design: Ideal for homes where space is limited.
  • Dual functionality: Provides both heating and cooling, making it a year-round solution.

However, like any machine, regular maintenance is key to ensuring longevity. In this case, years of neglect had taken a toll.


The Solution: A Step-by-Step Repair Process

At AirGreen, we approach repairs with precision and care, ensuring no detail is overlooked. Here’s how we tackled this project:

1. Diagnosing the Issues

We conducted a thorough inspection, identifying three major problems:

  • A burned-out fan motor that required replacement.
  • Clogged filters restricting airflow and causing overheating.
  • A refrigerant leak that needed immediate sealing and recharging.

2. Cleaning and Maintenance

Our team began by thoroughly cleaning the unit. Dust and debris had accumulated in the internal components, further straining the system. We replaced the filters and cleaned the evaporator and condenser coils, restoring proper airflow.

3. Repairing and Replacing Parts

Next, we replaced the faulty fan motor with a high-quality OEM part, ensuring compatibility and durability. For the refrigerant leak, we used advanced sealing techniques and recharged the system to its optimal level.

4. Final Testing

Before declaring the job complete, we tested the unit extensively. The heat pump was now operating quietly and efficiently, with full heating and cooling functionality restored.


The Outcome: A Happy Customer and a Revitalized Heat Pump

When we demonstrated the repaired unit to the homeowner, their disbelief quickly turned to delight. The COAIRE ductless heat pump, once thought to be scrap, was now working like new. Our repair gave the unit an extended lifespan, saving the customer the cost of a full replacement.


Lessons for Homeowners: How to Care for Your Heat Pump

This service call serves as a reminder of the importance of regular maintenance. To keep your ductless heat pump in peak condition, follow these tips:

1. Clean or Replace Filters Regularly

  • Dirty filters reduce efficiency and strain the system.
  • Replace filters every 3-6 months, depending on usage.

2. Schedule Annual Maintenance

  • A professional inspection can catch minor issues before they become major problems.
  • Maintenance includes cleaning coils, checking refrigerant levels, and inspecting parts.

3. Address Issues Promptly

  • Strange noises, reduced performance, or unusual odors should be addressed immediately to avoid costly repairs.
