Air Conditioning in Condominiums: How to Avoid Conflicts Between Neighbors on the South Shore

Smart solutions for harmonious air conditioning in condominium buildings

At AirGreen, we understand how air conditioning in condominiums can quickly become a source of tension between neighbors, especially when outdoor units are poorly positioned, too noisy, or installed without proper coordination. On the South Shore, where residential buildings and condos are widespread in Brossard, Saint-Lambert, Longueuil or Saint-Bruno, these challenges are especially critical. That’s why we offer our CVAC (HVAC) expertise to ensure installations that are high-performing, quiet, and compliant with condo regulations.

Why can air conditioning in condominiums become a problem?

There are many challenges when several co-owners want to improve their indoor comfort:

• Noise issues from outdoor units disturbing neighbors.

• Building aesthetics diminished by visible or uncoordinated installations.

• Lack of uniformity in equipment choices.

• Conflicts over space on balconies or shared walls.

• Violations of building or municipal regulations.

We've faced these issues many times during our wall-mounted heat pump installations in Longueuil or wall-mounted air conditioner installs in Boucherville, and every time, our role has been to act as a technical mediator between individual needs and collective requirements.

AirGreen Case Study: Wall-mounted heat pump installation in Saint-Lambert

In a condominium located in Saint-Lambert, on the South Shore, we were called in to install a Gree Extreme 18,000 BTU wall-mounted heat pump. The request seemed simple, but the condo board had very strict requirements:

• The noise level had to be under 50 dB.

• The outdoor unit could not be visible from the street.

• Refrigerant piping had to be invisible on the building’s exterior.

Our team conducted a complete thermal analysis of the condo to confirm the required power. We then proposed a customized solution:

• A Gree Extreme model, known for its low sound output (only 45 dB in eco mode).

• Side wall mounting with anti-vibration brackets, at the back of the building.

• Aesthetic pipe covers, matching the color of the wall.

• Installation completed in less than 5 hours, with no power interruptions for neighbors.

The result? A happy client, zero disturbance for co-owners, and an installation 100% compliant with both municipal codes and the condo rules.

Best practices for harmonious HVAC installations in condominiums

We’ve learned a lot from our interventions in South Shore condominiums. Here are our key recommendations:

1. Carefully review the condo rules

Before starting any project, we always ask our client for a copy of the condo bylaws. Some prohibit units visible from the street, others require written approval from the condo board.

2. Choose quiet and compact equipment

Models like the Fujitsu KZAH 12,000 BTU or the Sharp ZU1 15,000 BTU are ideal for discreet installations. These systems offer:

• Low noise levels.

• Excellent energy efficiency (SEER over 20).

• A sleek design, easy to integrate on balconies or side walls.

3. Think collectively: shared installation strategies

We also offer shared HVAC projects: multiple wall-mounted units grouped on a designated technical wall, or centralized installations (e.g., through a central air handler like the Goodman R-32 serving several apartments).

4. Communicate openly between neighbors

Before starting any project, we encourage clients to host an info session or distribute a work notice. Clear communication avoids future frustration.

5. Work with a specialized company like AirGreen

With over 300 wall-mounted air conditioner installations on the South Shore, we understand the unique challenges of condo living. Our teams follow strict protocols to ensure safety, compliance, and satisfaction at every level.

Available grants for condominiums

Good to know: even in condominiums, several models installed by AirGreen are eligible for Hydro-Québec’s LogisVert grants, as long as the project meets certain criteria:

• The unit replaces a less efficient system (baseboard heaters, old A/C unit).

• Power and energy performance meet the program’s requirements.

For example:

• Gree Extreme 18,000 BTU = up to $1,704 in grants.

• Fujitsu KZAH 12,000 BTU = eligible for up to $2,172.

• Bosch BOVA IDS Premium R-454B, installed for centralized condo systems, offers superior performance and is often subsidized over $3,000.

Our condo projects on the South Shore: real case examples

• Saint-Hubert: simultaneous installation of 4 wall units on the same building, with reinforced soundproofing.

• Brossard (Sector C): replacing window A/C units with high-efficiency Fujitsu wall models.

• Longueuil (Vieux-Longueuil): creating a shared installation plan for 6 co-owners, including a maintenance charter.
