Repair of a Carrier Wall-Mounted Heat Pump in Brossard

Breathing New Life into a Trusted Machine: The Story of a Carrier Mini Split

At AirGreen, we pride ourselves on being the go-to HVAC specialists in Montreal, Laval, Longueuil, the North Shore, and the South Shore. Recently, we were called to a home in Brossard to tackle a repair that perfectly illustrates our commitment to quality, expertise, and customer satisfaction.

Our customer, a long-time owner of a Carrier wall-mounted heat pump, had started noticing issues with their unit. The once reliable machine had been struggling to turn on, leaving the family in discomfort as temperatures fluctuated. Despite its age, the customer was attached to the unit, having relied on it for years to keep their home comfortable year-round. The task was clear: extend the life of this trusted companion and restore it to its former glory.


The Challenge: Diagnosing the Problem

When we arrived, the heat pump was unresponsive. Our skilled technicians conducted a thorough inspection to identify the root cause. Here’s what we found:

  • Electrical glitches: The heat pump wasn’t receiving consistent power due to a worn-out capacitor. This small yet crucial component often fails with age, causing the unit to lose its ability to start.
  • Dust and debris accumulation: Over the years, the system's internal components had gathered a significant amount of debris, reducing its efficiency and causing minor overheating.
  • Wear and tear on the blower motor: The motor that circulates air throughout the home was running intermittently, leading to uneven temperatures.

With a clear diagnosis in hand, we got to work.


Our Process: Restoring the Carrier Mini Split

We believe in transparency and craftsmanship. Here’s how we tackled the repair:

  1. Replacing the capacitor: This tiny yet essential part was swiftly swapped out, ensuring the heat pump could reliably power up.
  2. Deep cleaning of internal components: Using professional-grade equipment, we meticulously cleaned the evaporator coils, fan blades, and filters to improve airflow and system efficiency.
  3. Blower motor adjustment: Rather than replacing the motor outright, we fine-tuned its settings and lubricated the bearings, saving the customer unnecessary costs while ensuring smooth operation.

The Result: Like-New Performance

After a few hours of work, the Carrier wall-mounted heat pump was humming like it was brand new. The once-problematic system now:

  • Heats and cools efficiently, providing consistent temperatures throughout the home.
  • Operates quietly, enhancing the family’s comfort without the distracting noise of a struggling unit.
  • Offers peace of mind, with a few additional years of reliable service ahead.

Our customer was thrilled with the outcome. Instead of replacing their beloved Carrier system, they now have a machine that’s ready to handle the seasonal demands of Quebec’s climate.


Why Choose Repair Over Replacement?

Repairing an existing heat pump can be a smart decision, especially when:

  • The unit is well-built. Carrier machines are known for their durability, making them excellent candidates for repair.
  • Repairs are cost-effective. In this case, the customer spent a fraction of the cost of a new installation while extending the unit’s lifespan.
  • Environmental impact matters. Repairing instead of replacing reduces waste, contributing to a greener planet.
