In Sainte-Rose, many brick houses built in the 1970s and 90s are looking to modernize their heating and air conditioning systems. It was in this context that we installed a Midea central heat pump in a typical bungalow in the neighborhood, to provide true year-round comfort while reducing electricity bills.
Context: replacing an energy-intensive system with a modern solution
Our client had an existing forced-air heating system combined with an old central air conditioning unit. The challenges were clear:
-
High electricity consumption and limited heating performance;
-
Unequal comfort between rooms in the house;
-
A noisy outdoor condenser, located too close to the ground and vulnerable to snow;
-
Desire to take advantage of a more environmentally friendly solution, compatible with energy efficiency programs.
We therefore offered him a Midea EVOX G3 central heat pump , an R-454B model of about 3 tons, perfectly suited to the size of the bungalow and to Laval winters.
The Midea EVOX G3 central heat pump: the heart of home comfort
The Midea EVOX G3 is a next-generation central heat pump designed to work in tandem with an electric furnace or air handling unit. It allows you to:
-
Air conditioning for the entire house in the summer via existing ducts;
-
Efficient heating in mid-season and winter , greatly reducing reliance on electric elements or an old furnace;
-
Power modulation thanks to variable speed technology, for stable and quiet comfort.
By choosing Midea, the customer benefits from:
-
With excellent energy efficiency (high SEER2 and HSPF) ;
-
Using R-454B refrigerant, which is more environmentally friendly than an R-410A system;
-
A solution designed for northern climates , capable of operating in cold weather with optimized defrosting cycles.
Visible details of the outdoor installation
The photo clearly illustrates the Midea outdoor unit installed on the brick wall of the house:
-
The device, which is dark grey in color, is mounted on sturdy wall brackets fixed in the concrete foundation;
-
The installation height provides significant clearance from the ground , which protects the condenser from the accumulation of snow, ice, and dirt;
-
The large side-exhausting fan allows for efficient air removal , while maintaining a pleasant noise level for the customer and the neighborhood;
-
To the right of the unit, a properly installed electrical disconnect box can be seen, in accordance with the electrical code and manufacturer requirements.
This configuration ensures:
-
Free air circulation around the heat pump;
-
Easy access for maintenance and service;
-
Vibration reduction is achieved through console mounting and the use of anti-vibration accessories.
Interior integration: consistent comfort in all rooms
Even though the photo only shows the exterior, this Midea EVOX G3 central heat pump is connected to an existing air distribution system inside the house:
-
The outdoor unit is connected to an air manager inside via insulated, carefully routed and protected refrigerant lines;
-
Air is distributed to each room through the original ducts, allowing the owner to enjoy the same level of comfort in all areas : living room, bedrooms, basement, etc.
-
The main thermostat in the house now controls the Midea heat pump and the backup electric furnace, automatically switching between them based on the outside temperature.
The result: the house benefits from a complete central system , but with the modern technology of a high-performance heat pump.
Winter performance and defrost management
In Sainte-Rose, as elsewhere in Laval, winters can be harsh. The Midea EVOX G3 is designed for:
-
Continue to heat efficiently even when the temperature drops well below zero;
-
Automatically manage defrost cycles to keep the outdoor heat exchanger ice-free;
-
Prioritize energy efficiency by using the heat pump as long as it remains advantageous compared to backup electric heating.
The elevated installation shown in the photo is essential for:
-
Allow the snow to accumulate on the ground without blocking the device;
-
Facilitate the flow of defrost water;
-
Prevent premature corrosion by keeping the bottom of the unit away from puddles and splashes.
It is these details that extend the lifespan of the equipment and maintain its performance year after year.
