All-in-one: it heats and cools from inside the room, with no separate outdoor unit.
A box that goes through the wall and holds the unit. It is installed following the manufacturer's instructions so water drains to the outside.
This is where the unit exchanges heat with the outdoor air. It must stay clear.
A dedicated connection matched to the unit's voltage and amperage.
On the unit or through a wall thermostat, depending on the model.
Under a window, the unit must leave curtains, sill and opening free, and let air move through the room.
A custom comfort project in a condo in the Côte-des-Neiges sector
In this project in Côte-des-Neiges–Notre-Dame-de-Grâce, our AirGreen team installed a Trane ProSpace PTAC system . This type of equipment, commonly found in hotels, student residences, and condos in downtown Montreal, integrates directly through the wall to provide efficient heating and cooling in a single space.
The installation had a dual objective: to replace an old energy-consuming device and to offer the occupant four-season comfort without the need for bulky equipment.
Why choose the Trane ProSpace PTAC system?
The Trane ProSpace is renowned for its reliability and efficiency in small and medium-sized spaces. Unlike wall-mounted heat pumps or central air conditioners, the PTAC is built directly into the wall.
Notable advantages:
-
Independence of the service area : each unit operates autonomously, ideal for a condo or multi-residential housing.
-
Heating and air conditioning in one unit , without the need for ducts.
-
Compact installation , limiting the interior footprint and preserving living space.
-
Simplified maintenance , directly accessible from the front.
-
Stable performance in all seasons, adapted to the rapid temperature variations of Montreal's climate.
Key steps of installation
For this project, our AirGreen technicians followed a methodical process to ensure optimal operation and aesthetic integration.
1. Removing the old device
The condo already had a suitable wall mount. We removed the old unit, cleaned the wall mount, and checked the condition of the perimeter insulation.
2. Preparing the wall
After removal, signs of wear and dust were visible around the opening. We reinforced the seal and prepared the area for the new unit by ensuring good insulation against air and moisture.
3. Installation of the new Trane ProSpace unit
The unit was precisely inserted into the existing opening. Particular attention was paid to the peripheral sealing , in order to avoid any air infiltration or energy loss.
4. Electrical connection
The connection was made on a dedicated circuit, compliant with Quebec electrical standards, guaranteeing safety and efficiency.
5. Commissioning and verification
After connection, we carried out a series of tests:
-
Checking heating mode and air conditioning mode.
-
Airflow and sound level control.
-
Adjustments of comfort settings according to customer preferences.
Challenges encountered and solutions provided
-
Aesthetic constraint : the wall opening had slight irregularities. We applied finishing work to even out the contours and ensure a beautiful visual integration.
-
Energy efficiency : To maximize insulation, we added an additional sealing strip around the box.
Results obtained
Thanks to this installation, the customer now benefits from:
-
Immediate comfort in summer and winter.
-
From an autonomous and discreet system .
-
A reduction in operating costs compared to its previous device.
