Repair of a Hitachi Ductless Heat Pump in Repentigny

Saving a "Scrapped" Heat Pump: A Customer's Delightful Surprise

At AirGreen, we pride ourselves on our ability to deliver reliable, professional, and efficient HVAC services. Our recent service call in Repentigny is a testament to our team's expertise and commitment to customer satisfaction. When the client reached out to us, they were under the impression that their Hitachi Ductless Heat Pump had reached the end of its life. The unit had stopped functioning properly, and they believed that replacing it was the only option. However, we saw an opportunity to breathe new life into this machine, extending its serviceable years and saving our customer a significant expense.


The Challenges We Faced

When we arrived at the client’s home in Repentigny, we were greeted by a worn-out Hitachi ductless heat pump mounted above a doorway. The customer explained that the unit had been struggling to maintain a comfortable indoor climate, producing inconsistent airflow and occasional strange noises. Upon closer inspection, we noticed some build-up in the internal components and suspected electrical connection issues that were causing the unit to underperform.

This wasn’t just a routine repair; it was a chance to demonstrate our dedication to giving HVAC systems a second chance.


Our Step-by-Step Repair Process

1. Comprehensive Diagnostics

Our first step was to carefully inspect the unit. We focused on:

  • Electrical components: Ensuring the connections were intact and free from corrosion.
  • Refrigerant levels: Checking for any leaks or imbalances that could impact efficiency.
  • Internal cleanliness: Removing dust, debris, and build-up that had accumulated over the years.

Our thorough examination revealed an issue with the compressor’s relay switch, which had failed and was preventing the system from cycling on effectively. Additionally, we discovered that the drain line was partially clogged, causing intermittent water leakage.


2. Expert Repairs and Maintenance

We got to work on restoring the heat pump to peak condition:

  • Replaced the faulty relay switch, ensuring the compressor could power up seamlessly.
  • Cleared and sanitized the drain line to prevent future water issues.
  • Conducted a deep cleaning of the evaporator and condenser coils, significantly improving heat exchange efficiency.
  • Tightened electrical connections and tested the unit for consistent operation.

3. Final Testing and Calibration

Once the repairs were complete, we performed multiple operational tests to ensure the heat pump was running smoothly. We recalibrated the system to optimize performance and verified that the airflow was consistent across all fan speeds.

By the end of the service call, the Hitachi heat pump was functioning like new. The customer was thrilled to see their "scrapped" unit brought back to life with just a few expertly executed repairs.

Hitachi heat pumps are known for their durability, innovative technology, and energy efficiency. This particular model, while older, still had a lot of potential. With proper maintenance and timely repairs, these units can provide years of reliable heating and cooling.

These qualities made our job even more rewarding—we knew this machine deserved a second chance.
