A tailor-made comfort solution for Montreal's modern residential spaces
At AirGreen , we recently installed a ProSpace PTAC system in a home in the Côte-des-Neiges–Notre-Dame-de-Grâce neighborhood, an area known for its mixed-use buildings and renovated residences. This installation perfectly illustrates our expertise when it comes to integrating a complete heating and cooling system into a small space, while preserving the aesthetics and energy efficiency of the space.
Why choose a ProSpace PTAC system?
The PTAC ProSpace is a compact, high-performance solution designed to provide both heating and cooling in a single wall-mounted unit. Unlike conventional wall-mounted heat pumps, the PTAC system does not require an external condenser: the entire mechanism is integrated into the wall, simplifying installation and reducing maintenance costs.
This type of device is ideal for:
-
Urban condos or rental apartments with limited space;
-
Individual offices or commercial premises for occasional occupation;
-
Student residences or hotel units looking for an independent comfort solution per room.
A discreet and efficient AirGreen installation
The unit installed in Côte-des-Neiges fits perfectly under a large window, providing optimal air diffusion in the room while remaining silent and energy efficient .
Our technicians carefully positioned the unit at the recommended height and distance to maximize air circulation, while ensuring a perfect wall seal to prevent any heat loss.
The installation required:
-
A calibrated wall cutout , reinforced by an insulated sealing frame;
-
A dedicated electrical connection with independent circuit breaker;
-
An aesthetic adjustment of the surround to harmonize everything with the baseboard and existing decor.
Comfort, simplicity and performance
The PTAC ProSpace offers immediate comfort thanks to its integrated electronic control . The user can adjust the temperature, fan speed and operating mode (heating or cooling) with just a few clicks.
This model also features a dehumidification mode and an easy-to-maintain filtration system , ensuring healthier air every day.
Minimal maintenance and maximum durability
PTAC systems are built to last. Their robust design and direct front access allow for quick maintenance without complex disassembly.
At AirGreen, we also offer an annual maintenance program for these units, including filter cleaning, coil inspection, and electrical and thermal performance monitoring. This preventative service extends the life of the unit and maintains its optimal energy efficiency.
A solution perfectly adapted to the needs of the Montreal sector
In an urban context like Montreal, where old buildings coexist with modern constructions, the PTAC ProSpace represents an excellent compromise between comfort, efficiency and aesthetics.
Thanks to its through-hole installation, it avoids the need to add an outdoor condenser — often complex to install in condominiums or heritage buildings in the city center.
Residents benefit from:
-
Year-round comfort , no matter the season;
-
From an independent system per unit, simplifying energy management;
-
Quick installation , without major work or conduits.
AirGreen expertise at the service of each project
At AirGreen, every HVAC installation project is carried out with the same rigor. Our experts always evaluate:
-
The thermal needs of the housing;
-
Existing insulation and solar exposure;
-
The structural and electrical constraints of the building.
This approach allows us to offer the most efficient and aesthetic solution , adapted to each residential or commercial configuration.
By choosing AirGreen, our customers benefit from a complete professional service: analysis, installation, maintenance and support throughout the life of the system.
Whether it's a ProSpace PTAC , a wall-mounted heat pump or a central system , our team ensures lasting comfort and total peace of mind.
