In Saint-Léonard, brick bungalows with large side yards are common, and many homeowners want to upgrade their heating/cooling systems while making the most of their existing ductwork. In this project, our AirGreen team installed a Midea central heat pump in a typical single-family home in the area, replacing an older, less efficient system.
Our goal: to offer the customer uniform comfort throughout the house, substantial energy savings and a clean and durable outdoor installation, perfectly suited to the Montreal winter.
The client's need: to replace an energy-intensive central system
Before our intervention, the Saint-Léonard residence was equipped with a traditional central heating system, combined with an aging central air conditioning unit. The challenges were clear:
-
High electricity consumption, particularly during periods of extreme cold.
-
Unequal comfort between the ground floor and the upper floor.
-
A noisy, outdated outdoor condenser that is not very effective during heat waves.
-
A desire to maximize existing air ducts rather than switching to a wall-mounted system.
The client wanted a modern, centralized solution that:
-
Uses the existing conduits;
-
Provides efficient air conditioning and heating;
-
Remains reliable in the long term;
-
It blends in neatly with the brick facade.
The AirGreen solution: a Midea EVOX central heat pump
After assessing the home's heat load and ductwork configuration, we recommended installing a Midea EVOX G3 central heat pump with a capacity of approximately 2.5 to 3 tonnes. This type of system is perfectly suited to single-family homes in Saint-Léonard.
The advantages of a Midea central heat pump
-
High-efficiency inverter technology : the compressor power adjusts continuously according to the actual demand, allowing for significant energy savings.
-
Stable heating performance even in cold weather, which greatly reduces the need for supplementary electric heating.
-
Uniform comfort in all rooms connected to the ducts, without sudden temperature fluctuations.
-
Silent operation , both for the outdoor condenser and the indoor air manager.
This choice allows the customer to benefit from a complete four-season system, while enhancing the value of the existing central installation.
A neat and safe outdoor installation
The photo clearly shows the dark gray Midea condenser mounted on a red brick wall, above the concrete foundation. Several installation elements were considered to ensure performance, durability, and accessibility.
Sturdy wall brackets and ample clearance.
The Midea central heat pump is installed on galvanized wall brackets , securely anchored to the foundation. This configuration:
-
Keeps the unit above ground level , away from snow, ice and standing water;
-
Limits vibrations and noise transmitted to the structure;
-
Frees up ground space for grounds maintenance or passage in the side yard.
Clearances and air circulation
The condenser is a side-discharge type: the air is expelled from the side of the unit. Therefore, we have maintained significant clearances:
-
Sufficient distance from the brick wall, fence and vegetation;
-
Positioning that avoids blowing air directly towards passageways;
-
The orientation was designed to reduce noise perceived from the windows and the neighborhood.
These choices are essential to ensure optimal operation of the Midea central heat pump, both summer and winter.
Management of refrigeration connections and cabling
The insulated refrigeration pipes and wiring are neatly routed along the wall:
-
Low passage over the foundation, then vertical ascent in a discreet cover to the attic or mechanical room;
-
Protection against shocks, UV rays, frost and humidity;
-
Visually harmonious integration with the brick facade and existing elements (gutters, fence, exterior lighting).
The condensation drain is directed to an area clear of the ground, in order to avoid puddles near the foundation and ice formation on walking areas.
Interior integration: centralized comfort throughout the home
Inside, the Midea central heat pump is coupled to an air management system connected to the existing ductwork. We have:
-
Checked the condition and sizing of the ducts to ensure proper air distribution;
-
Optimized the plenum and fittings to reduce pressure losses;
-
Calibrated the fan for balanced airflow between the different rooms of the house.
The customer now benefits:
-
Consistently comfortable on all floors;
-
Precise control thanks to the central thermostat;
-
A system capable of operating in heating or cooling mode depending on the season, with a simple transition at the thermostat level.
Winter performance and energy savings
The climate in Saint-Léonard, like everywhere in Montreal, brings long, harsh winters. The Midea EVOX central heat pump was chosen because:
-
Its excellent heating efficiency at low outdoor temperatures;
-
Its ability to significantly reduce electricity consumption compared to purely resistive heating;
-
Its stable, smooth operation improves the compressor's durability.
In practice, the system heats the house for a large part of the winter. The electric backup only kicks in during periods of intense cold, allowing the customer to reduce their Hydro-Québec bills while gaining comfort .
Compliance, safety and commissioning
As with all our installations, we have applied best HVAC practices in Quebec:
-
Electrical connection by a certified electrician , on a dedicated circuit with a suitable circuit breaker;
-
Rigorous vacuuming of refrigeration lines to eliminate air and moisture;
-
Pressure, heating and air conditioning tests;
-
Checking the direction of rotation of the fan, the electrical currents and the protections;
-
Detailed explanation to the customer on the use of the thermostat, operating modes and maintenance to be expected.
The Midea central heat pump is thus delivered turnkey , ready to operate in the best conditions for many years.
