A Complete Transformation of Residential Comfort on the South Shore
At AirGreen, every HVAC installation project is an opportunity to bring tangible improvements to our clients' comfort, energy efficiency, and peace of mind. This recent central heat pump installation in Boucherville perfectly illustrates our approach: technical rigor, adaptation to the realities of existing buildings, and attention to detail at every stage.
In this typical single-family home on the South Shore, the client wanted to replace an old, inefficient electric heating system with a modern solution capable of providing constant comfort in both winter and summer, while significantly reducing energy costs. After a thorough analysis, we chose the MIDEA EVOX G3 2 Tonnes, a central system renowned for its cold climate performance.
Why the MIDEA EVOX G3 Was the Ideal Choice for This Home
Exceptional Performance in Quebec Climate
The installed MIDEA EVOX G3 central heat pump offers reliable heating capacity down to -30°C, an essential criterion for the harsh winters of Boucherville, Montreal, and the South Shore. This model is ENERGY STAR® certified for cold climates, ensuring superior energy efficiency.
Key Technical Specifications:
- Capacity: 24,000 BTU (2 tons)
- SEER2: 18.6
- HSPF2: 10.0
- Refrigerant: R-454B (low GWP)
- Outdoor Sound Level: 59 dB(A)
- WiFi: Included
- Warranty: 12 years compressor / 12 years parts / 10 years labor
This type of system not only provides efficient heating but also ensures uniform air conditioning during the summer.
Specific Challenges Encountered During Installation in Boucherville
Integration into an Existing Structure
The house was equipped with an old duct network, with certain limitations:
- Irregular duct dimensions
- Partial insulation in some sections
- Restricted access for the outdoor unit
We had to adapt our approach to optimize system performance without undertaking major work.
Outdoor Wall Installation: Precision and Durability
As can be seen from this installation, the outdoor unit was solidly fixed on steel wall brackets, directly onto a brick facade. This technical choice offers several advantages:
- Protection against accumulated snow on the ground
- Better air circulation around the unit
- Reduced vibrations thanks to robust supports
We also took care to:
- Ensure perfect alignment of the unit
- Install anti-vibration dampers
- Protect the electrical line with a secure and compliant enclosure
Key Steps of Our HVAC Installation
1. Complete Thermal Analysis
Before any installation, we conducted a detailed evaluation:
- House area
- Insulation
- Room orientation
- Client's specific needs
This allowed us to confirm that the 2-ton (24,000 BTU) format was perfectly suited.
2. Duct Preparation and Adaptation
We:
- Cleaned and inspected existing ducts
- Adjusted certain sections to improve airflow
- Checked the overall sealing of the system
3. Indoor Unit (Air Handler) Installation
The MIDEA EVOX G3 indoor unit was installed in an optimized technical space, allowing for:
- Easy access for HVAC maintenance
- Uniform air distribution throughout the house
4. Outdoor Unit Placement
Secure wall mounting, connection of refrigerant lines, and electrical installation compliant with Quebec standards.
5. Commissioning and Calibration
We performed:
- A complete vacuum pull (micron test)
- A pressure check
- Airflow calibration using Constant AirFlow 2.0 technology
Final Result: Comfort, Quietness, and Savings
Within the first few days of installation, the client noticed:
- A stable temperature in all rooms
- A significant reduction in indoor noise
- An immediate decrease in energy consumption
This type of central heat pump allows for intelligent modulated operation, avoiding sudden cycles and ensuring continuous comfort.
Available Subsidies and Return on Investment
This installation is eligible for the Hydro-Québec LogisVert subsidy, amounting to up to:
👉 $2,280
This factor plays a key role in the project's profitability, significantly reducing the initial cost.

The job tools
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Baseboards and electric furnaces turn 1 kWh of electricity into 1 kWh of heat. A heat pump delivers more: that is its COP. At Hydro-Québec’s rate D (11.142¢/kWh above 40 kWh a day, since 1 April 2026):
Hydro-Québec: a heat pump can be up to three times more efficient than baseboards for heating in the colder months.
Estimate per kWh of heat, at the chosen temperature, using the certified COP from the product page. Taxes, access charge and backup heat not included.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
How the job unfolds
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the ducts, the current indoor module, the electrical panel and the planned spot for the outdoor unit.
The equipment combination, capacity and price, in writing. We check whether the combination qualifies for assistance programs.
Access protected, old unit disconnected and removed when it is being replaced.
Electric furnace or air handler, with its coil, connected to the supply and return ducts.
On a level base, raised above the snow, with free space all around.
Insulated, they enter through a sealed opening and run to the indoor coil.
Dedicated circuits, accessible disconnect, a thermostat that works with the heat pump and the backup heat.
Leak test, vacuum, start-up, airflow check and a test of both modes.

What we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
It captures or rejects heat outside. It sits on a level base, above the snow, with free space all around.
The insulated refrigerant lines enter the house through a sealed opening and run to the indoor coil.
A shut-off switch near the outdoor unit isolates it safely for service.
Sitting on the indoor module, it moves heat between the house air and the refrigerant.
Electric furnace or air handler: its fan pushes air through the ducts. The electric backup takes over in extreme cold.
Supply ducts bring air to the rooms; returns bring it back to the unit. Their condition matters as much as the unit's.
It protects the coil and the fan. A dirty filter cuts airflow, so it gets checked regularly.
It runs the heat pump and the backup heat. It must be compatible with the installed system.
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.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Check the indoor module's filter.
- Clear winter debris from the outdoor unit.
- Test cooling before the heat arrives.
- Check the filter more often in peak season.
- Keep registers and returns clear.
- Watch condensate drainage near the coil.
- Change or clean the filter.
- Test heating and backup heat before the cold.
- Book periodic maintenance.
- Clear snow around the outdoor unit.
- Store nothing in front of the indoor module.
- Note any unusual noise or smell and call us.
The right pages, at the right time
Four statements: true or false?
It all comes down to details you have just seen.
1. A central heat pump uses the house's ducts.
It connects to the existing ducts to heat and cool everywhere.
2. In extreme cold, electric backup heat can take over.
The indoor module (furnace or air handler) works with the heat pump and takes over in extreme cold.
3. The filter only gets changed when the unit breaks down.
A dirty filter cuts airflow. It gets checked regularly.
4. You can reuse the old unit's size without checking.
The house may have changed: insulation, windows, added rooms. Capacity is confirmed on site.
