Repair of a Hitachi Wall-Mounted Heat Pump in Montréal

Breathing New Life Into an Aging Heat Pump: A Tale of Expertise and Trust

When it comes to HVAC services in Montréal, AirGreen is no stranger to challenges. Recently, we had the opportunity to demonstrate our expertise by restoring a Hitachi ductless wall-mounted heat pump to optimal working condition. This wasn’t just any service call—it was a mission to bring an "out-of-service" machine back to life, much to the delight of a customer who thought replacement was the only option.

The Challenge: A Heat Pump That Seemed Beyond Repair

Our customer in Montréal reached out to us with a problem that many homeowners dread. Their Hitachi wall-mounted heat pump, a trusted appliance for years, had stopped working effectively. Cooling during the summer and heating during the chilly months had become inconsistent, with strange noises and uneven airflow. To make matters worse, they were convinced that the machine was beyond repair—a total loss.

This is where AirGreen stepped in. We pride ourselves on offering solutions where others see dead ends. Our team saw this as an opportunity to not only repair the machine but also to save our customer from the significant expense of a full replacement.


The Diagnostic Phase: Finding the Problem

One of the key steps in any repair job is accurate diagnosis, and this situation was no different. Upon arriving at the customer's residence in Montréal, we conducted a comprehensive assessment of the machine. Here’s what we found:

  • Clogged Filters: Years of operation had led to dirt and debris accumulation, restricting airflow.
  • Damaged Internal Components: The motor and a few electrical connections showed signs of wear and tear, causing irregular operation.
  • Refrigerant Levels: A slight refrigerant leak had compromised the unit’s cooling capacity.
  • Exterior Wear: Montréal’s humid summers and frigid winters had taken a toll on the machine’s exterior, though the internal structure remained sturdy.

Armed with this information, our technicians created a step-by-step plan to restore the machine to working order.


The Repair Process: Turning Challenges Into Triumphs

Step 1: Deep Cleaning the Unit

We began by thoroughly cleaning the heat pump. This wasn’t just a quick surface wipe; we disassembled the unit to access the internal filters, coils, and blower. Removing years of dirt and buildup ensured that airflow would no longer be restricted.

Step 2: Addressing the Refrigerant Leak

A leak in the refrigerant system can be a critical issue, but our team is equipped with the tools and expertise to handle it. We located and sealed the leak, then recharged the system with the precise amount of refrigerant, ensuring the machine could cool effectively once again.

Step 3: Electrical Repairs

The heat pump’s motor had been operating intermittently due to loose connections. We secured the wiring, replaced worn-out components, and tested the motor to confirm consistent performance.

Step 4: Preventative Maintenance

Finally, we applied protective measures to help the unit withstand Montréal’s extreme weather. This included rust-proofing vulnerable areas and ensuring that all moving parts were lubricated for smooth operation.


Customer Reaction: From Skepticism to Satisfaction

When we completed the job, we ran the heat pump through several cycles to ensure it worked flawlessly in both heating and cooling modes. The results spoke for themselves—consistent airflow, efficient cooling, and no unusual noises. The customer, who initially believed the machine was destined for the scrap heap, was thrilled to have their Hitachi heat pump functioning like new again.

In their own words: “I can’t believe you saved this machine. I thought I’d need a replacement, but you’ve given it a second life. Thank you!”
