Repair Service of a Daikin Mini Split Heat Pump in Montreal

Bringing Comfort Back: The Journey of a Daikin Mini Split Heat Pump Repair

At AirGreen, we understand that a reliable heat pump is essential for comfort, especially during the fluctuating temperatures of Montreal. Recently, we embarked on an intricate repair project involving a Daikin wall-mounted mini split heat pump. This was no ordinary repair—it was a tale of meticulous troubleshooting, extensive testing, and the art of restoring perfection.

The Initial Call: A Freon Leak Revealed

When our client reached out to us, they were experiencing a frustrating problem: their Daikin mini split wasn’t cooling as expected. Even in Montreal’s moderate climate, a malfunctioning heat pump can make the days seem hotter and the nights colder. Upon our arrival, we knew we were dealing with a possible refrigerant issue. The key to a proper diagnosis? Pinpointing the exact source of the leak.

Armed with specialized equipment, we first conducted a series of preliminary inspections to rule out any simple fixes. It quickly became clear: this wasn’t just a minor setback. The system’s freon levels were dangerously low, pointing to a significant leak that needed our immediate attention.

The Search Begins: Detecting the Leak

Our journey began with a thorough check of all components. Using pressurized nitrogen (azote) testing, we injected nitrogen gas into the system. This process is invaluable for leak detection because nitrogen doesn’t condense or mix with the refrigerant, making it perfect for tracking down even the tiniest of leaks.

Our technicians meticulously applied soapy water to joints, fittings, and connection points, watching carefully for any telltale bubbling—an unmistakable sign of escaping gas. It’s like finding a needle in a haystack, but with the right expertise and patience, it’s possible.

And there it was, a tiny, almost imperceptible crack in one of the system’s copper lines. While it may seem small, this flaw was the culprit behind the significant drop in refrigerant, robbing our client of optimal comfort.

Precision Repairs: Fixing the Problem

Once we located the leak, the repair work began. We delicately sealed the crack using high-quality brazing techniques to ensure a lasting fix. Brazing is an art form that requires the perfect balance of heat and precision, and our team has mastered this craft.

With the repair completed, we needed to ensure the integrity of the system before recharging it with refrigerant. We performed another pressure test with nitrogen, holding our breath and hoping for zero pressure drops. Success! The system was holding perfectly, proving our repair had resolved the issue.

Adding Freon: The Heart of the Cooling System

The next step was to add the right amount of freon to the Daikin mini split. Unlike other systems, Daikin units require precise refrigerant levels to function efficiently. Adding too much or too little could compromise performance and longevity. We carefully measured and recharged the system, checking and double-checking our gauges to ensure everything was perfect.

The Moment of Truth: Performance Testing

Now came the moment of truth: turning the system on and witnessing the return of cold, crisp air. It roared back to life, humming smoothly as cool air once again filled the room. The customer’s joy was palpable; after all, there’s nothing quite like the feeling of immediate relief and comfort.

Our final step was to perform a series of performance tests, ensuring every component was working harmoniously. We measured temperature drops, airflow rates, and overall efficiency. Each test confirmed that the Daikin mini split was back to operating at peak performance, ready to tackle Montreal’s summer and winter demands.
