Precise comfort for an open-plan space with mezzanine and metal staircase
At AirGreen , we have just completed the HVAC installation of a Gree Livo R32 wall-mounted heat pump in an apartment in Southwest Montreal . The client's objective was clear: to obtain stable heating in the winter and quiet air conditioning in the summer, without encroaching on the aesthetics of a minimalist living room with a metal staircase and textured ceiling. Our proposal relies on a Livo R32 , known for its seasonal performance, its discreet operation and its compatibility with the new R-32 environmental requirements.
The choice of the Livo R32: efficiency, discretion, reliability
The Gree Livo R32 fits naturally into the apartments and plexes of Greater Montreal thanks to:
-
R-32 (A2L) refrigerant : better volumetric efficiency and advantageous environmental balance.
-
Inverter compressor : fine modulation of power, uniform temperature and low consumption.
-
Capacity range : 9,000 to 24,000 BTU, allowing precise sizing according to the volume to be treated.
-
Quiet in low mode : ideal for an open living room where you work or watch TV.
-
Discreet side display showing the set temperature (here 19°C ), readable without dominating the decor.
By selecting the Livo R32 , we ensure four-season comfort with lower operating costs compared to traditional electric baseboards.
Interior layout: air diffusion designed for the mezzanine
The wall head is installed in the upper part , at the corner of the living room, in line with the staircase. This location is not accidental:
-
It promotes a longitudinal sweep along the wall and a vertical sweep which breaks the stratification towards the mezzanine.
-
It leaves the passage free under the stairs while avoiding obstacles to high suction.
-
It provides easy access to filters for periodic maintenance.
The blowing radius covers the living area and the dining area. We adjust the direction of the shutters to limit air jets towards the staircase (to avoid hot air accumulating at height in winter) and promote gentle recirculation at occupancy height.
Technical details of the installation: cleanliness and performance
Our HVAC installation follows a rigorous protocol to ensure the durability of the system:
-
Through-hole with slight outward slope for gravity drain of condensates, with vapor barrier and watertight seal.
-
White capping matching the wall finish to protect the refrigerant connections and the communication/power cable.
-
Optimized line length : short path between the head and the outdoor condenser, reducing pressure losses and maintaining nominal efficiency.
-
Brazing and Nitrogen : Nitrogen purge during brazing, pressure test then deep vacuum ; add refrigerant as needed depending on actual length.
-
Electrical validation : dedicated circuit breaker, conductor gauge checked, connection to the unit box according to Gree specifications.
-
Commissioning : control of blown temperatures , compressor intensity, verification of cycles and communication.
The result is a clean finish , with no visible ducts, and acoustic performance at the level expected for a residential environment.
Sizing and comfort strategy in vertical housing
Rooms with a mezzanine or open staircase require a specific approach:
-
We calculate the sensible and latent load taking into account the additional volume in height.
-
In heating , a slight downward blow limits the accumulation of hot air near the ceiling.
-
In air conditioning , a horizontal sweep at medium speeds allows more distant areas to be reached without direct air currents on the occupants.
-
A correctly configured Auto mode and tight setpoint ranges prevent frequent starts.
This fine adjustment makes the Livo R32 particularly comfortable in spaces with complex geometry.
Outdoor winter management: robustness and silence for the neighborhood
Outside, the condenser is installed with regulatory clearances to ensure non-recirculated air flow. Key points:
-
Raised support when required to clear snow and allow defrost runoff .
-
Silent blocks to limit vibration transmission to the structure.
-
Protected routing of facade connections with watertight connections and continuous insulation against frost.
These precautions ensure reliable operation in cold weather while preserving neighborhood peace and quiet.
Grants and administrative support
The Livo R32 , thanks to its high efficiency and its new generation refrigerant, may be eligible for assistance depending on the option chosen and the performance indices: programs such as Rénoclimat and certain local bonuses in Montreal, Laval, Longueuil, North Shore, South Shore . We support the customer in:
-
eligibility verification ;
-
documentation (installation photos, serial numbers, forms);
-
the required performance evidence .
HVAC Maintenance: Actions That Make the Difference
To maintain performance and longevity:
-
Clean filters every 6 to 8 weeks;
-
Keep the area around the condenser clear (leaves, snow, objects);
-
Schedule an annual AirGreen inspection : coil cleaning, apparent pressure/load measurements, electrical checks and updating usage guidelines based on the housing history.
Regular maintenance prevents overconsumption and maintains quiet operation .
Common Mistakes We Avoid
-
Orientation of the shutters towards the staircase: we favor an angle which stabilizes the temperature at the level of the occupants.
-
Drain without slope or vapor barrier: we ensure gravity flow and lasting waterproofing.
-
Connections that are too tight or poorly insulated: we respect the bending radii and protect the insulation against UV rays.
-
Condenser too close to an obstacle : we guarantee the clearances required for optimal heat exchange.
Result for the customer
-
Uniform temperature at 19–21°C in winter, stable coolness in summer.
-
Reduced energy bill compared to baseboards and portable appliances.
-
Respected aesthetics : discreet interior unit, flush capping, no visible cables.
-
Peace of mind : a well-sized, quiet system supported by AirGreen after-sales service .

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 room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.

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.
Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
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.

The right pages, at the right time
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
