Optimal comfort for a downtown condo thanks to a compact and efficient solution
In the vibrant heart of Ville-Marie , a condo owner wanted to modernize their interior comfort without compromising aesthetics or energy efficiency. At AirGreen , we met this goal by installing a Trane ProSpace PTAC system , an ideal HVAC solution for compact urban spaces requiring integrated heating and cooling in a single wall-mounted, through-baseboard unit.
A solution adapted to condos and urban housing
Packaged Terminal Air Conditioner (PTAC) systems like the Trane ProSpace are distinguished by their all-in-one design. Perfectly suited to condos, hotels, and individual housing in downtown areas, they allow for:
-
Efficient heating and cooling in all seasons.
-
A compact installation , without a bulky external unit.
-
Simplified maintenance , with direct access from the inside.
In this project, the configuration of the condo—located in a recent apartment building near downtown Montreal—lent itself ideally to this type of device.
Technical specifications of the installation
The installation of this Trane ProSpace was carried out with precision by our RBQ and CMMTQ certified technicians. Key steps included:
-
Preparation of electrical wiring : installation of a certified power cord, calibrated according to the power of the unit.
-
Through wall mounting : adjustment of the existing cut-out to ensure optimal positioning and perfect sealing around the frame.
-
Optimized condensate drainage : gravity-driven with a slight inclination, avoiding any water backflow.
-
Thermal and acoustic insulation check : addition of an anti-vibration seal around the housing to minimize operating noise.
Our team also calibrated the integrated thermostat and checked the line voltage to ensure safe and long-lasting commissioning.
Why the Trane ProSpace is a smart choice
The Trane ProSpace offers several advantages that make it a great option for urban environments:
-
Stable performance even during extreme temperature variations.
-
Efficient compression technology , reducing energy consumption.
-
Individual room temperature control , ideal for multi-unit buildings.
-
Discreet and modern design , blending perfectly into the interior decor.
In addition, this series meets the requirements of modern comfort: silent operation, automatic restart in the event of a power failure, and minimal maintenance thanks to an easily accessible filter .
Challenges encountered and AirGreen solutions
One of the challenges of this installation was the proximity of the load-bearing wall and the limited space for managing electrical wiring. Our technicians were able to overcome this constraint by:
-
Using a discreet wiring channel that matches the baseboard.
-
Integrating a protected electrical outlet on the adjacent wall for direct and compliant power supply.
The result: a clean, safe and aesthetic installation, compliant with Quebec electrical standards and with the quality of finish that distinguishes AirGreen.
End result: efficiency, comfort and peace of mind
As soon as it was switched on, the customer could see the difference:
-
Even temperature throughout the condo.
-
Almost imperceptible noise level.
-
Excellent thermostat responsiveness.
This installation perfectly illustrates AirGreen's ability to adapt HVAC solutions to each residential environment , taking into account the spatial, aesthetic and energy constraints specific to urban housing in Greater Montreal.
