Providing a high-end heating and cooling solution in a small space is a challenge we rise to every day at AirGreen. Installing a wall-mounted heat pump in a condo requires more than just a powerful unit — it demands meticulous planning, a deep understanding of the technical constraints of small spaces, and above all, flawless execution. Here’s a detailed look at how, at AirGreen, we turn condos into spaces that are just as comfortable and energy-efficient as a house.
The perfect balance between compact size, performance, and efficiency
Condos, especially in Montréal, Laval or Longueuil, often come with architectural and technical challenges: narrow balconies, load-bearing walls, strict condo board rules, lack of existing central systems, and more. And yet, the wall-mounted heat pump remains the most suitable HVAC solution for these compact environments.
We consistently recommend models that are quiet, discreet, but above all, highly efficient, such as:
-
Fujitsu KZAH – Known for its slim indoor profile and Inverter technology.
-
Gree Sapphire – Excellent performance down to -30 °C, perfect for our Québec winters.
-
Sharp ZU1 – A well-balanced unit in terms of price, performance, and sleek design.
Case study: Installation of a Fujitsu wall-mounted heat pump in a Longueuil condo
In a recent project in Longueuil, a client living in an 850 sq. ft. condo wanted to replace an old portable A/C unit with a solution that was quieter, more powerful, and more energy-efficient. After an on-site evaluation, we recommended the Fujitsu KZAH 12,000 BTU wall-mounted heat pump, R-32 model.
Key steps in the project:
-
Technical evaluation of the space
We assessed the layout of the open-concept living room, sun exposure, potential refrigerant line length, and condo board regulations. -
Choosing the indoor unit
Thanks to its compact and stylish design, the KZAH blended seamlessly into the home décor without taking up living space. -
Outdoor unit installation
Installed on a wall bracket on the rear balcony, the unit meets all noise and clearance regulations. We added an anti-vibration system to keep noise to an absolute minimum. -
Minimal drilling and aesthetic finish
The installation was designed to minimize visual impact indoors, with a clean wall penetration and cover channels painted to match the wall color. -
Startup and calibration
At startup, we fine-tuned the target temperature, optimized the auto mode, and trained the client on how to make the most of the remote features.
Why choose a wall-mounted heat pump for a condo?
1. Unmatched energy efficiency
Given the smaller size of condos, a 9,000 to 12,000 BTU wall unit is typically enough to ensure year-round thermal comfort. Our Energy Star-certified models deliver up to 40% in heating and cooling savings.
2. Quick, clean installation with no major work
Unlike central systems, a wall-mounted heat pump requires no ducts, no mechanical room access, and no structural alterations.
3. Grant eligibility
All of our high-efficiency wall-mounted heat pumps are eligible for Hydro-Québec’s LogisVert subsidies, up to $1,704, significantly reducing installation costs for condo owners.
4. Quiet and discreet
Our latest models run at a sound level below 23 dB, ideal for open-concept living rooms, bedrooms, or home offices.
Practical advice for condo owners
Before installing:
-
Check your condo board rules regarding exterior modifications.
-
Choose a contractor certified by the RBQ and a member of the CMMTQ (like AirGreen).
-
Go for a unit that uses R-32 or R-454B refrigerant, more environmentally friendly.
During installation:
-
Make sure the work is done in a single day, with no mess or excessive noise.
-
Request a leak test on the refrigerant lines.
After installation:
-
Schedule annual maintenance with AirGreen to keep your unit running smoothly and maintain the warranty.
-
Learn how to use the different modes (heating, dehumidification, auto) to stay comfortable all year round.
