Installation of a Midea wall-mounted heat pump in Saint-Lambert

Carefully designed for four-season comfort

At AirGreen , we believe that a wall-mounted heat pump installation must combine performance, aesthetics, and durability. This service call in Saint-Lambert , on Montreal's South Shore, perfectly illustrates this approach: a residential project where precision and cleanliness were at the heart of our work.

The owner had just renovated his terrace and wanted a heating and air conditioning solution that was discreet , efficient, and above all well integrated into the architecture of his house.

Step 1 — Choosing the Right Midea System

After a complete thermal assessment of the residence, our team recommended the installation of a Midea 12,000 BTU wall-mounted heat pump , renowned for its excellent value for money and superior energy efficiency .
This Inverter model offers:

• Quiet operation thanks to a variable speed compressor;

• Smart defrosting , essential for Quebec winters;

• And a SEER efficiency of over 20 , reducing electricity consumption.

Step 2 — Optimal positioning of the outdoor condenser

The condenser was installed on a raised aluminum structure , guaranteeing:

• Free air circulation under the unit ;

• Protection against snow and debris ;

• And effective drainage in case of rain or melting ice.

The unit was carefully fixed to the side wall of the terrace, respecting the necessary clearances for future maintenance and to avoid any return of hot air to the facade.

Step 3 — Refrigeration connection and professional finishing

Our technicians then proceeded to install the refrigeration circuit . The insulated copper piping was routed through the wall with a controlled slope to ensure optimal flow of oil and condensate.

For aesthetic and durability reasons, the refrigeration line was wrapped in a waterproof white sheath and secured with UV-resistant black ties . This finish protects the lines from the elements and blends perfectly with the beige facade of the house.

Step 4 — Electrical Connection and Commissioning Tests

A dedicated 15A circuit was run directly to the electrical panel, with a GFCI to maximize safety.
Once the system is powered on, we have:

• Checked factory refrigerant charge using a digital manifold;

• Performed a nitrogen leak test ;

• Performed a complete vacuum draw before final pressurization.

The start-up was seamless. In less than ten minutes, the interior temperature had already dropped from 26°C to 22°C, demonstrating the system's immediate cooling power .

Step 5 — Explanations and maintenance advice

We took the time to show the customer how to use the different modes (heating, air conditioning, dehumidification, ventilation) and program the remote control for automatic comfort.

Our recommendations for maintaining system performance:

1. Clean the internal filters every two months;

2. Check the cleanliness of the outdoor condenser at the beginning of each season;

3. Schedule professional AirGreen maintenance annually to maintain the manufacturer's warranty.
