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.

Breathing New Life into an Aging FUJITSU Heat Pump

At AirGreen, we take pride in every project, from new installations to extending the life of existing HVAC systems. This recent service call in Terrebonne showcases our commitment to excellence and our ability to deliver results that delight our customers. This repair project involved a FUJITSU Mini Split Heat Pump that had seen better days. Instead of jumping straight to recommending a replacement, we rolled up our sleeves and tackled the issues head-on, breathing new life into this resilient machine.


The Challenge: An Old Machine with a Big Story

When our team arrived at the client’s residence in Terrebonne, we were greeted by a familiar sight: an aging FUJITSU Mini Split Heat Pump that had weathered years of use. The unit was struggling to keep up with the demands of the household, and the customer was at a crossroads—replace or repair?

After a thorough inspection, we identified several issues:

  • Clogged coils and filters reducing the system’s efficiency.
  • Electrical components that had experienced wear and tear over the years.
  • A refrigerant line that needed attention to restore the system’s cooling capabilities.

Instead of recommending an immediate replacement, we assured the customer that with some professional care, this trusted machine could continue serving their home for many more years.


The Solution: A Step-by-Step Approach to Excellence

Our repair process was meticulous, ensuring that every component of the FUJITSU Heat Pump was evaluated and optimized. Here’s how we brought the unit back to life:

1. Cleaning and Maintenance

The first step was to deep clean the unit. Years of dirt and debris had accumulated on the coils and filters, restricting airflow and reducing efficiency. We:

  • Removed and thoroughly cleaned the filters.
  • Conducted a chemical wash on the coils to restore their heat exchange efficiency.
  • Cleared the drainage system to prevent water buildup.

2. Electrical Repairs

Next, we focused on the electrical system. We replaced worn-out components, ensuring the unit could operate safely and efficiently. Our team checked:

  • Capacitors and relays for any signs of wear.
  • Electrical connections to prevent potential failures.
  • The control board to ensure seamless communication within the system.

3. Refrigerant System Adjustment

Finally, we turned our attention to the refrigerant system. After identifying a minor leak in the refrigerant line, we:

  • Sealed the leak using high-quality materials.
  • Recharged the system with the correct amount of refrigerant.
  • Tested the unit to ensure optimal cooling performance.

Why This Repair Was Worth It

Our customer in Terrebonne was thrilled with the results. By choosing to repair rather than replace, they saved significantly on costs while extending the life of their FUJITSU Mini Split Heat Pump. More importantly, the unit now operates with near-new efficiency, providing consistent comfort throughout the home.

This project is a perfect example of why AirGreen is trusted by so many households across Montreal, Laval, Longueuil, the North Shore, and the South Shore. We prioritize our clients’ needs and always strive to find the most cost-effective, reliable solutions.

  • Extended Lifespan: Proper maintenance and targeted repairs can add years to your system’s life.
  • Environmental Impact: Repairing rather than replacing reduces waste and is a more sustainable option.
  • Restored Efficiency: A well-repaired system can perform almost as efficiently as a new one.

Frequently asked questions

What people ask us about this kind of work

9 questions
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?
Yes, it heats and cools. Its capacity drops in very cold weather; the operating range depends on the model and is listed on its spec sheet.
Wall-mounted or multi-zone: how do I choose?
One wall head and one condenser outside: the direct solution for a room or an open area. For two to five rooms, a multi-zone puts one head in each room on a single condenser.
Where does the outdoor unit go?
Where it stays above the snow, clear and accessible, away from walkways. We decide it with you during the estimate.
Are there grants?
Depending on the model and your situation, assistance programs may apply, including Hydro-Québec's LogisVert. AirGreen checks the model number before quoting an amount. See the grants.
Do I need a permit?
Rules vary from city to city: location, distances, noise. See permits and by-laws, and we check for your address.
Does AirGreen hold the required licences?
Yes. AirGreen holds RBQ licence 5645-9605-01, subclasses 15.8 Ventilation, 15.10 Refrigeration and 16 Electricity.
