Each number is a point we check on site. Switch between summer and winter to watch air and heat move.

In summer, the outdoor unit rejects the house's heat outside.

  1. Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.

  2. The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.

  3. Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.

  4. A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.

  5. The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.

  6. On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.

  7. The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.

Restoring Comfort: How We Brought a Samsung Mini Split Back to Life

In the heart of Repentigny, one of our valued customers faced a challenge that many homeowners can relate to—a malfunctioning Samsung wall-mounted heat pump. This machine, an essential part of their home’s comfort system, had started leaking refrigerant. Instead of replacing the entire unit, the customer turned to us at AirGreen to bring their heat pump back to its full functionality. This is the story of how we repaired, revived, and extended the life of this trusty Samsung mini split.


The Problem: A Leaking Refrigerant System

Refrigerant leaks are among the most common issues with ductless heat pumps, and this Samsung unit was no exception. Over time, wear and tear had caused tiny leaks in the system, leading to a drop in performance. The machine was no longer cooling or heating effectively, and its efficiency had plummeted. The customer was understandably concerned—should they replace the entire unit or invest in repairs?

At AirGreen, we pride ourselves on finding cost-effective solutions. After a thorough diagnostic, we confirmed that the unit was structurally sound and that repairing the refrigerant system would give it several more years of reliable service.


The Repair Process: Precision and Expertise

Our repair process began with a comprehensive inspection of the heat pump. Using state-of-the-art leak detection tools, we pinpointed the exact locations of the refrigerant leaks. Once identified, we carefully sealed the leaks using industry-approved methods, ensuring a durable and lasting repair.

Here’s a breakdown of the steps we took:

  1. System Shutdown and Inspection
    We safely powered down the unit and checked all components for visible signs of wear, including the refrigerant lines and connections.

  2. Leak Detection
    Using advanced tools like an electronic leak detector, we traced the source of the refrigerant loss.

  3. Sealing the Leaks
    After isolating the problem areas, we applied high-quality sealants to the leaks. This step required precision to ensure that the seals would hold under the system's normal operating pressures.

  4. Recharging with Refrigerant
    With the leaks sealed, we recharged the system with the correct type and amount of refrigerant. This is a critical step to restore the machine’s efficiency and performance.

  5. Performance Testing
    Finally, we ran the unit through a series of tests to verify that it was operating correctly. We measured airflow, temperature output, and overall energy efficiency to ensure everything was back to peak condition.


The Outcome: A Thrilled Customer

After completing the repair, the Samsung mini split was as good as new. The customer was delighted to see their machine working flawlessly again, knowing that they had saved money by opting for a repair instead of a full replacement. With the refrigerant leaks resolved and the system recharged, the heat pump was ready to provide efficient heating and cooling for years to come.

What should I have ready before calling?
The model (on the unit's label), the error code if there is one, the symptoms and how long they have lasted.
Repair or replace?
It depends on the unit's age, the failure and the cost of parts. We present the options after the diagnosis.
Does a wall-mounted heat pump heat in winter?
