An HVAC installation project adapted to condo living in downtown Montreal
In the Ville-Marie borough, in the heart of downtown Montreal, our AirGreen teams recently completed the installation of a Trane ProSpace PTAC unit . This type of system, widely used in modern hotels and condos, combines heating and air conditioning in a compact, through-the-wall format, making it particularly suitable for high-density urban environments where space is limited.
This example perfectly illustrates our expertise in residential HVAC installation in demanding technical contexts.
Choosing a PTAC system: simplicity and efficiency in a limited space
PTAC (Packaged Terminal Air Conditioner) units are distinguished by their all-in-one design. The unit combines the compressor, evaporator, and fan into a single console, installed directly at the bottom of the wall. In this project:
-
Brand: Trane , renowned for its robustness and reliability.
-
Model: ProSpace , designed specifically for condos, urban residences and small commercial buildings.
-
Type: PTAC , through the wall, allowing the unit to reject heat directly outside.
The main advantage for condo owners in Montreal is the absence of a bulky outdoor condenser, which simplifies space constraints on balconies and flat roofs.
Installation challenges encountered in this Ville-Marie condo
Installing a Trane ProSpace PTAC unit in a downtown condo presented some challenges that we had to overcome:
Adaptation to existing buildings
The load-bearing walls of the residential towers require particular precision when cutting and integrating the unit. Our team took care to work with existing materials without compromising the building's thermal insulation.
Condensate management
In this project, we favored gravity drainage directly connected to the building's technical column, thus avoiding the addition of a condensate pump which would have required additional maintenance.
Aesthetics and integration
The unit, located just below the window, blends discreetly into the apartment's decor. Carefully finished moldings and flooring ensure a clean and harmonious installation without compromising the condo's aesthetic.
Benefits for the customer
Installing this Trane ProSpace PTAC offers the owner several immediate benefits:
-
4-season comfort : heating in winter, air conditioning in summer, ventilation in mid-season.
-
Ease of use : integrated thermostat and remote control available.
-
Energy Efficiency : Trane's modern PTAC units are designed to meet today's efficiency standards.
-
Reliability : Trane is recognized for the durability of its components, reducing maintenance requirements.
-
Space saving : no bulky outdoor unit on the balcony or roof.
