Repair of a Hitachi Ductless Heat Pump in Laval

Bringing Life Back to a Trusted Hitachi Heat Pump in Laval

At AirGreen, we pride ourselves on doing more than just installations—we specialize in giving HVAC systems a second chance at life. Recently, we had the opportunity to bring new hope to a long-serving Hitachi ductless heat pump in a cozy Laval home. The customer initially thought the unit was beyond repair, but our dedicated team proved otherwise. This service call became an inspiring story of ingenuity, professionalism, and craftsmanship.


The Call for Help: A Heat Pump on Its Last Leg

Our journey began with a distressed call from a homeowner in Laval. Their Hitachi wall-mounted heat pump, a machine they had relied on for years to keep their home comfortable year-round, had stopped functioning properly. To them, it seemed like the end of the line for this hardworking unit. Facing the prospect of replacing the system entirely, they reached out to AirGreen for a professional assessment.

Upon arrival, our expert technicians conducted a thorough diagnostic, leaving no wire uninspected. What we found was both challenging and exciting: a combination of issues, from refrigerant leaks to wear and tear on vital components. While others may have recommended scrapping the unit, we saw an opportunity to repair and restore.


The Repair Process: Precision, Expertise, and Care

Restoring the Hitachi ductless heat pump required more than just a standard service. Here's how we tackled the challenge step by step:

1. Comprehensive Diagnostic

Our team used advanced diagnostic tools to identify the core problems:

  • A significant refrigerant leak affecting cooling efficiency.
  • Minor corrosion on the compressor connections.
  • A clogged drainage system, which was causing water to accumulate and reduce functionality.

2. Strategic Component Repair

Instead of replacing the entire system, we focused on repairing specific components:

  • Sealing the refrigerant leak: Using specialized equipment, we sealed the leak and recharged the system with eco-friendly refrigerant.
  • Rejuvenating the compressor: By carefully cleaning and reconnecting corroded parts, we extended the life of the compressor.
  • Clearing the drainage system: Our technicians meticulously cleared blockages to restore optimal water flow.

3. Rigorous Testing

Once the repairs were complete, we ran the unit through rigorous performance tests. The Hitachi heat pump not only met but exceeded its original efficiency, proving that even older systems can regain their vigor with the right care.


Why Repair Instead of Replace?

The customer was thrilled to learn that their trusted Hitachi heat pump could be saved. This decision came with several benefits:

  • Cost-Effectiveness: Repairing the system was significantly less expensive than purchasing a new one.
  • Environmental Responsibility: Extending the life of the unit helped reduce waste, aligning with sustainable practices.
  • Trusted Comfort Restored: The homeowner could once again rely on their heat pump for consistent heating and cooling.
