South Shore specifics
From suburbs to condos: every area has its constraints
The South Shore mixes very different neighbourhoods. Towns like Saint-Constant and Saint-Basile-le-Grand have many single-family homes, often with a yard that makes placing the outdoor unit easy. Brossard and Longueuil add denser areas, with condos and plexes where board approval and roof or balcony access come into play.
In every case, winter is the same: we favour cold-climate units and an installation that protects the outdoor unit from snow and ice.
Before every installation, we check:
- floor area, insulation and existing heating (baseboards, furnace, ducts);
- the outdoor unit’s location and winter clearance;
- municipal rules and, in condos, the board’s rules;
- the model’s eligibility for the LogisVert rebate;
- the electrical panel’s capacity.

Excellent service, well-organized company and clear communication.
I wanted to share my excellent experience with this small, local company in the Southwest. Frédérick, the owner, personally handles the quotes, which is much appreciated. He presented us with several machines, taking the time to thoroughly explain each option. After receiving quotes from three companies, we quickly decided to go with them, both for the quality of their service and the clarity of their explanations. During the installation, there were two of them, and they did an absolutely outstanding job. They took care of the old machine and even cleaned their workspace with their own vacuum cleaner before leaving—a level of attention to detail that makes all the difference. Even my dog, Maria, supervised the whole process and trusted them, which speaks volumes! The entire installation took no more than three hours. Frédérick then took the time to explain all the features of the machine and the remote control in detail, including its self-cleaning function. We've already successfully tested the heating mode, and I'm really looking forward to trying the cooling mode. I'll definitely call you, Frédéric, to come and install the Wi-Fi system this summer! I recommend this company to everyone, without hesitation!
Excellent, fast, and professional service. They pay attention to detail. I highly recommend this company.
