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 high-performance wall-to-wall HVAC solution, expertly installed by AirGreen
On Montreal's North Shore, where climate variations require precise and reliable thermal management, we recently installed a Trane R32 PTAC heat pump with a capacity of 12,000 BTU . This compact, self-contained unit, often used in hotel complexes or multi-unit residences, was chosen for its consistent performance, its wall-mounted format, and its compatibility with spaces without ventilation ducts.
This project perfectly illustrates our approach: rigorous, professional and focused on the real needs of our clients.
Why choose a 12,000 BTU Trane R32 PTAC heat pump?
All-in-one technology with pass-through installation
This PTAC (Packaged Terminal Air Conditioner) unit is designed to be inserted directly into the wall, simplifying installation and reducing heat loss. The Trane PTHG1201HAA model stands out for its compactness ( 42 x 21.5 x 16 in ), its 220V voltage, its low noise level (51 to 54 dB) , and its use of R-32 refrigerant , known for its energy efficiency and low environmental impact.
Quiet and continuous performance
Whether in air conditioning or heating mode, the heat pump maintains a stable indoor temperature. It has several operating modes: heat pump heating, electric backup, air conditioning, ventilation only , as well as a memory function and an automatic anti-freeze mode .
Ideal for multi-unit buildings and commercial spaces
With its discreet design and consistent performance, this unit is perfect for:
-
Senior residences
-
Hotel complexes
-
Rental apartments
-
Multi-unit buildings
Looking back on our successful installation on the North Shore
Project background
The client, a residential building owner on the North Shore of Montreal, wanted to replace an old PTAC unit that had become noisy and energy-intensive. After consultation, we recommended the Trane PTAC R32 | 12,000 BTU heat pump , offering excellent performance/price ratio and direct compatibility with the existing wall opening.
Steps of the intervention
-
Wall opening inspection : confirmation that the dimensions of the old appliance matched those of the new one.
-
Removal of existing unit : clean disassembly, without damaging the interior finish.
-
Wall preparation : insulation and sealing of the opening.
-
Installation of the new unit : secure fixing, 220V electrical connection, level check.
-
Operational tests : monitoring of temperature, air flow, noise level, and the efficiency of the different modes.
-
Customer training : explanation of Trane control panel use, advanced functions and basic maintenance.
Results obtained
-
Improved thermal comfort from the first hours
-
Reduction of noise perceived by occupants
-
Anticipated reduction in energy consumption of 20 to 30%
-
Smooth operation even on a very hot day (initial setting at 61°F during testing)

Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Four statements: true or false?
It all comes down to details you have just seen.
1. A PTAC needs a separate outdoor unit.
It is an all-in-one unit that goes through the wall.
2. The outdoor grille must stay clear.
That is where the unit exchanges heat with the outdoor air.
3. Any electrical outlet will do.
It needs a connection matched to its voltage and amperage.
4. A PTAC can heat and cool a room.
That is its job: all-in-one, under the window, through the wall.
