A compact and efficient wall-mounted solution to optimize comfort in a residential space in Vaudreuil-Dorion
At AirGreen, we are regularly called upon for HVAC installation projects that require both efficiency, compactness, and custom adaptation to a building’s constraints. This is exactly the type of challenge we tackled during this recent installation of a TRANE ProSpace PTAC (Packaged Terminal Air Conditioner) unit in a residence in Vaudreuil-Dorion, in Montérégie.
This project is a perfect example of our expertise in integrated wall-mounted HVAC systems, often used in settings such as hotels, senior residences, or apartments requiring individual climate control per room.
Why choose a TRANE ProSpace PTAC system?
The decision to install a TRANE ProSpace PTAC air conditioner was driven by several factors:
-
Compact, horizontal design, ideal for low wall installations
-
Self-contained unit that provides both heating and cooling
-
Outstanding reliability from the TRANE brand, widely known in the industry for durability
-
Simplified maintenance with front-access components
-
No ductwork required, minimizing drilling or major interior modifications
This model is commonly used in multi-family or commercial spaces, but it’s becoming increasingly popular in residential settings seeking to segment comfort zones independently and in an energy-efficient way.
Installation context: adapting to an existing wall opening
When we were contacted for this installation in Vaudreuil-Dorion, the client was looking for a solution to replace an old inefficient wall-mounted system without undergoing major renovations. The wall already had a horizontal cutout, typical for PTAC installations. The previously installed unit had caused moisture infiltration and damaged the paintwork, which required careful wall preparation before installing the new unit.
Steps in installing the TRANE ProSpace PTAC
1. On-site evaluation and wall preparation
Our technicians began by inspecting the wall space, verifying the structural integrity of the existing opening. Special attention was paid to any residual moisture and the condition of the wall finish. We:
-
Scraped off the damaged paint residues
-
Applied a light antifungal treatment
-
Adjusted the edges of the opening for a perfect fit for the new unit
2. Integration of the TRANE ProSpace system
The unit was perfectly recessed into the wall opening, with close attention to leveling and alignment to ensure proper drainage and quiet operation. The electrical connection was completed with a dedicated breaker, meeting all safety standards for this type of equipment.
3. Airflow control and final testing
After installation, we proceeded with:
-
Airflow and ambient noise level checks
-
Performance tests in both heating and cooling modes
-
A full walkthrough with the client on how to operate the unit (thermostat, washable filters, etc.)
Specific benefits of this installation for the client
-
Individualized thermal comfort without the cost of a central system
-
Improved energy efficiency, with optimized room-by-room performance
-
Reduced ambient noise, thanks to TRANE's ventilation technology
-
Ease of maintenance, with filters accessible without complicated disassembly
-
No impact on building structure, no ductwork or suspended ceilings needed
