Specific residential and commercial air conditioning needs come up regularly on Montréal’s South Shore, including towns like Brossard, Longueuil, Saint-Hubert, Boucherville, and Saint-Lambert. At AirGreen, we’ve developed a deep understanding of our clients’ top priorities in this region. Thanks to years of on-site experience, we’ve identified the three most common air conditioning requests on the South Shore — and more importantly, how we respond to each one with precision, transparency, and expertise.
An energy-efficient wall-mounted air conditioner that can handle the South Shore summer heat
The number one concern for our South Shore clients is no surprise: energy efficiency in the face of rising summer temperatures. During the heat waves that hit Longueuil, Boucherville, or Châteauguay, our clients are looking for reliable, economical, and quiet solutions.
Our response: state-of-the-art units like the Fujitsu KZAH R-32
This model is one of the most popular choices among our residential customers on the South Shore. With capacities ranging from 12,000 to 18,000 BTU, it offers an excellent price-performance ratio and impressive energy efficiency (SEER above 25). This model is eligible for Hydro-Québec’s LogisVert rebates, significantly lowering the net cost for families.
Case study in Saint-Lambert
A client contacted us to replace an old, inefficient central air conditioner. With limited indoor space, we recommended a Fujitsu KZAH 12,000 BTU wall-mounted unit, perfectly suited to their apartment. Thanks to our quick installation in under a day, the family immediately enjoyed optimal thermal comfort, while saving on their bills.
The need for air conditioning in multi-unit buildings and duplexes on the South Shore
Many rental properties on the South Shore are plexes or small apartment buildings, especially in Longueuil and Saint-Hubert. Property owners are looking to standardize comfort across units while keeping operational costs under control.
Our solution: multisplit wall-mounted units like the Gree Multi-Zone Free Match
The Gree Free Match system powers up to 4 indoor wall-mounted heads using a single outdoor compressor. It’s the perfect solution for buildings with several units. We’ve completed numerous HVAC installations in plexes across Longueuil and Brossard, where the building configuration limited centralized options. This modular system, using R-32 refrigerant, saves space and allows for independent climate control in each unit.
Testimonial from Brossard
Mr. L. owned a triplex with three tenants, each with their own cooling preferences. Our team designed a custom solution with three Fujitsu wall units connected to a Gree Free Match 36,000 BTU outdoor unit. The entire system was installed in just two business days, including electrical wiring, wall brackets, and thermostat calibration.
The growing demand for ultra-quiet air conditioning systems
Noise level is a key concern, especially in quiet residential neighborhoods like Boucherville and Saint-Bruno-de-Montarville. Many of our clients ask for ultra-quiet units, particularly for bedrooms or home office spaces.
Our recommendation: the Sharp ZU1, a premium wall-mounted heat pump
The Sharp ZU1, with its ultra-quiet mode at 19 dB, is the perfect solution. This model, available from 15,000 to 24,000 BTU, is very popular in Candiac and La Prairie and combines thermal performance, advanced air filtration, and near-silent operation. It’s also eligible for government rebates, making it an even more attractive choice.
Service call in Boucherville
In a single-family home, we replaced a noisy old air conditioner with a Sharp ZU1 18,000 BTU. Thanks to our team’s expertise, we installed the new system without modifying the existing wiring, cutting installation costs. The result: discreet, efficient, and seamlessly integrated air conditioning that met the client’s expectations.

Common mistakes to avoid
Choosing an oversized unit
Many clients assume a larger air conditioner will cool more effectively. That’s incorrect. An oversized unit cools too quickly without properly dehumidifying, leading to discomfort.
Skipping annual maintenance
Neglecting HVAC maintenance shortens your system’s lifespan and increases energy use. At AirGreen, we offer customized maintenance plans for our South Shore clients.
Installing without a thermal load analysis
We always perform a comprehensive thermal analysis before each installation. This ensures we choose the right BTU capacity, based on sunlight exposure, insulation, and room volume.
