A tailor-made installation project for optimal comfort
In the residential sector of Côte-des-Neiges–Notre-Dame-de-Grâce , our AirGreen teams recently installed a PTAC ProSpace (Packaged Terminal Air Conditioner) system . This type of equipment, often found in hotels, condos, and urban apartments, offers a compact solution for heating and cooling, while optimizing the available space in the room.
The unit was carefully integrated under a window, a classic location that allows for both convenient access for maintenance and efficient energy performance. Thanks to its compact design, the ProSpace combines electric heating and air conditioning in a single unit, perfectly meeting the needs of an occupant wanting year-round comfort without the need for a central system.
Technical features of the installed ProSpace
The ProSpace model chosen here is an electric resistance PTAC . Its design incorporates:
-
All-in-one unit : heating and air conditioning integrated into the same unit.
-
Through-wall installation : the device takes up little space and blends harmoniously into the interior decor.
-
Accessible front controls : simple, user-friendly controls allow residents to easily manage the temperature.
-
Built-in filtration : Improves indoor air quality by reducing dust and certain particles.
-
Energy efficiency : complies with North American standards for this type of equipment.
Our technicians carried out the installation taking into account the requirements for waterproofing and wall insulation , in order to limit any energy loss around the device. Particular care was taken in managing condensate drainage , a crucial detail to ensure proper operation in summer.
Challenges encountered and solutions provided
In this project, one of the main challenges was to optimize the insulation of the wall passage. Since the PTAC passes completely through the wall, special attention was paid to:
-
The installation of an insulating sleeve to prevent any infiltration of outside air.
-
Adding weatherstripping seals to maintain winter comfort and improve energy efficiency.
-
Verification of electrical safety and compliance with the condo's distribution panel.
Thanks to these adjustments, the unit fits perfectly into the interior space and guarantees quiet and efficient operation.
The advantages of a PTAC system in an urban environment
In a neighborhood like Côte-des-Neiges–NDG, where there are many multi-residential buildings and condos, choosing a ProSpace PTAC system has several advantages:
-
Space saving : no need for ducts or bulky outdoor units.
-
Easy installation : just one wall hole and a dedicated power supply are all you need.
-
Independence per dwelling : each occupant controls their own comfort without depending on a central collective system.
-
Reduced maintenance : easy access for filter cleaning and technical checks.
-
Versatility : heating in winter, air conditioning in summer.
Customer testimonial and satisfaction
The owner of this property told us that his main goal was to replace an aging appliance that was consuming a lot of energy and generating noise. With this new ProSpace equipment, he now benefits from:
-
Reduced noise level , improving the quality of daily life.
-
Better temperature control , especially during the summer when urban heat is intense.
-
A reliable and durable solution , backed by the manufacturer's warranty and AirGreen's expertise.
