Optimizing residential comfort with a high-performance wall-mounted heat pump
At AirGreen , we know that the indoor comfort of a home in Montreal, Laval, Longueuil, on the North Shore or the South Shore depends on a well-chosen and properly installed HVAC system. This is exactly what we achieved during the recent installation of a Goodman wall-mounted heat pump in a duplex in the Saint-Léonard district.
Our team was tasked with replacing an old wall-mounted air conditioner that had become inefficient and noisy. The choice fell on a Goodman wall-mounted model, renowned for its reliability, energy efficiency, and durability in the Quebec climate.
Context of the project in Saint-Léonard
The installation involved a typical residential space in Saint-Léonard: a duplex with interior divisions requiring uniform distribution of heat and cool air. The old unit, installed over 15 years ago, was showing signs of wear: loss of performance during hot weather, excessive noise, and high energy consumption.
The owner wanted a modern, energy-efficient solution that was eligible for local subsidies to reduce his electricity costs while improving the comfort of his home.
Technical details of the installation
Choice of device

Type : Wall-mounted heat pump (mini-split)
-
Brand : Goodman
-
Capacity : 12,000 BTU (enough for a space of 450 to 550 sq. ft.)
-
Efficiency : Energy Star certified, high SEER2, optimized HSPF2
-

Installation Steps
-
Dismantling the old wall-mounted air conditioner : safe removal of the unit and its existing ducts.

Constraints encountered
-
Limited space : The indoor unit had to be placed above a door, which required millimeter precision to ensure sufficient clearance for the air damper.
-
Drainage management : We opted for gravity drainage to avoid the need for a condensate pump, which reduces the risk of long-term breakdown.
Results obtained
Following installation, the customer benefits from optimized thermal comfort all year round . The Goodman heat pump provides efficient cooling during the summer and stable heating on cool fall and winter days, while reducing energy bills compared to the old wall-mounted air conditioner.
The system is quiet, modern, and discreet, blending seamlessly into the home's interior. Furthermore, since the equipment is Energy Star certified, the homeowner is eligible for grant programs available to residents of Montreal, Laval, Longueuil, as well as the North and South Shores.
