Installation of a Lennox central heat pump in Rosemont–La Petite-Patrie

As part of a residential project in Rosemont–La Petite-Patrie , our AirGreen team completed the installation of a Lennox central heat pump in a typical Montreal building, complete with a stone basement, existing ductwork, and significant mechanical constraints. This type of configuration is common in this area and requires a methodical approach to ensure performance, reliability, and compliance.

A central system adapted to Montreal residences

The installed unit is a Lennox central heat pump , a choice renowned for its robustness, consistent heating and cooling performance, and seamless integration with existing ductwork. In this project, the system replaces older, less efficient equipment while maintaining the existing air distribution network architecture.

Central heat pumps are particularly well-suited to homes in Rosemont, where you often find:

• narrow technical basements,

• masonry or stone walls,

• existing metal conduits to be optimized rather than rebuilt.

Lennox central model – high-performance residential range

Even though the exact model isn't clearly displayed, the equipment is clearly a recent Lennox residential-grade central heat pump , compatible with current energy efficiency standards. This type of Lennox system is designed for:

• to provide stable heating during the Quebec winter ,

• to ensure uniform air conditioning in the summer ,

• to operate silently despite installation in a confined space.

Lennox remains a highly regarded brand for the quality of its components, the longevity of its indoor units, and the reliability of its electronic controls.

Installation details observed on the construction site

The installation, visible in the photos, highlights several important technical elements:

• Vertical central indoor unit , installed on a solid base in the basement.

• Direct connection to existing ducts , with a well-sealed metal plenum to limit air loss.

• Insulated refrigeration line , carefully protected along its entire height to prevent condensation and heat loss.

• Proper management of the mechanical space , despite stone walls and a configuration typical of old Rosemont buildings.

• Clear access for maintenance , an essential point for the durability of the Lennox system.

This type of installation requires specific expertise: every connection, every duct transition and every insulation detail has a direct impact on comfort and energy consumption.

Why a Lennox central heat pump in Rosemont?

In a densely populated area like Rosemont–La Petite-Patrie, homeowners are primarily looking for:

• consistent comfort across all floors ,

• a discreet solution , without visible wall units,

• a reduction in energy costs ,

• a reliable system to face Montreal winters.

The Lennox central heat pump perfectly meets these requirements, especially when installed and calibrated by a team that is familiar with the realities of Montreal buildings.

The AirGreen approach: precision and local adaptation

At AirGreen , we know that no two Montreal homes are truly alike. In this Rosemont project:

• We adapted the installation to the constraints of the stone basement .

• optimize existing conduits rather than imposing unnecessary modifications,

• ensured a clean and sustainable integration , in accordance with best HVAC practices.

Our goal remains the same: to deliver a system that performs well today, but is also reliable for the next 15 to 20 years.

Four-season comfort, without compromise

Thanks to this Lennox central heat pump , the occupants now benefit from:

• efficient and stable heating in winter,

• uniform air conditioning during heat waves,

• improved humidity control,

• of superior acoustic comfort.

This is exactly the type of solution we regularly recommend in Rosemont–La Petite-Patrie and similar neighborhoods in Montreal.
