A perfectly integrated interior head: silent comfort and air control in a bright room
The context: maximizing comfort without sacrificing aesthetics
At AirGreen , we are working on a ground floor in Villeray–Saint-Michel–Parc-Extension where the owner wants to improve the mid-season heating and summer air conditioning of a south-facing living room. The space is bright, with a large window and a tight lintel on the ceiling. The goal: to integrate a wall-mounted heat pump that remains discreet , quiet and easy to maintain , while ensuring even air diffusion.
We recommend the Gree Clivia R32 wall-mounted version, a good choice for its seasonal efficiency , its flexibility of installation in rooms with standard ceilings and its discreet display which disappears visually when not in use. This range operates on R-32 refrigerant , known for its energy efficiency and reduced charge.
The installation: a high, strategic and sustainable installation
Positioning and support of the inner head
-
The head is installed at the top , at an angle, a few centimetres from the ceiling to take advantage of the Coandă effect : the blown air runs along the ceiling and mixes better in the room, limiting cold areas or direct drafts.
-
We respect the side and top clearances recommended by the manufacturer, ensuring access for maintenance and correct reading of the probes.
-
The immediate proximity of the window requires attention to air discharge : we orient the horizontal shutters to avoid a direct blower on the window frame and preserve comfort.
Refrigeration path and condensate drainage
-
The drilling is carried out directly behind the head, with a slight outward slope for gravity drainage of condensate; this solution reduces complexity and eliminates potential noise from a pump.
-
Outside, the capping protects the refrigeration connections and the communication cable; the light color chosen blends in with the woodwork and limits solar heating.
-
Line lengths are optimized to minimize load losses and preserve seasonal efficiency .
Power supply
-
The head is connected to the condenser via communication wiring ; the main power supply to the system is provided by a dedicated circuit with a Code-compliant circuit breaker, sized according to the selected capacity.
-
An external disconnect switch is provided to facilitate future maintenance and diagnostics.
The advantages of the Gree Clivia R32 in everyday use
-
R-32 : better efficiency per unit charge, reduced carbon impact compared to R-410A, and stable performance in both air conditioning and heating.
-
Acoustic comfort : the fan design and battery shroud limit the noise level at low speeds, ideal for a living room or bedroom.
-
Discreet display and intuitive remote control : the requested temperature can be read at a glance without visual pollution.
-
Smart defrost (in heating mode): optimized cycles to maintain thermal stability inside.
-
Accessible filters : simple, tool-free cleaning that encourages regular HVAC maintenance .
Construction site challenges and AirGreen solutions
-
Low ceiling and air return
-
Our team chooses an installation height that avoids direct discharge to the ceiling. The shutters are adjusted to project the air in laminar flow then in gentle mixing .
-
-
Proximity to decorative objects
-
We advise the customer to keep a clear area under the head (baskets, shelves, thick curtains), so as not to disturb the reading of the probes and the air intake . A free zone of 1 m in front of the unit guarantees the best diffusion.
-
-
Drilling on the facade wall
-
Use of a sleeve with vapor barrier and insulation to prevent thermal bridges and condensation in the crossmember. The external seal is made with a UV-compatible elastomeric sealant .
-
-
Acoustic
-
Silent blocks and controlled tightening limit vibrations. A speed balance at the end of commissioning confirms the absence of parasitic whistling.
-
Commissioning: precision and traceability
-
Vacuum draw to the recommended threshold, stability checked with a vacuum gauge.
-
Cross-testing in heating and air conditioning to confirm overtemperature and subcooling within normal ranges.
-
Condensate flow control by water test: gravity flow without retention.
-
Submission of an installation report with technical photos and key values (pressure/ΔT/instructions), useful for guarantees and subsidies .
Results: consistent comfort, better directed air, bill under control
From the first hours of operation, the heat pump ensures noticeable thermal comfort , especially during rapid changes in sunshine. In summer, dehumidification improves the feeling of freshness and allows the setpoint to be reduced by one to two degrees. In mid-season and mild winters, the Clivia R32 limits the need for additional heating, helping to lower energy bills .
Good HVAC Maintenance Practices
-
Monthly : dusting of filters ; a clean filter ensures controlled consumption and a contained noise level .
-
Seasonal : visual inspection of the exterior capping and leaf clearance.
-
Annual (by AirGreen): electrical check, thermal sensors, deep cleaning of the evaporator, verification of the condensate flow , and validation of the refrigeration parameters .
-
Winter : maintain free access to the outdoor condenser (snow/ice) and avoid any obstruction of the grilles.
Grants and administrative support
The Gree Clivia R32 , depending on the BTU capacity and the efficiency ratings selected, can meet the program criteria in effect in Quebec. Our team assesses your eligibility , gathers the documents (invoices, installation photos, serial numbers) and guides you to the depot . Whether you are in Montreal , Laval , Longueuil , on the North Shore or the South Shore , we apply the same documentary rigor.
What this Villeray project demonstrates
-
A wall-mounted head can be integrated flush with the ceiling without compromising air diffusion if the clearances are respected and the shutters are correctly adjusted.
-
R-32 refrigerant is essential for its performance and its sobriety .
-
A short path and gravity condensate drainage simplify installation, reduce noise risks and improve reliability.
Practical advice before launching your project
-
Choose the capacity based on actual volumes, sunshine and insulation; oversizing does not provide more comfort and harms performance .
-
Think about placement : a well-positioned head is worth as much as the chosen model; avoid lofts and frontal obstacles .
-
Require documented vacuum sealing and functional testing in hot/cold modes.
-
Plan maintenance from the moment of installation; this is the guarantee of maintaining the capacity in extreme cold and the longevity of the machine.

The job tools
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
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.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.
Remote, modes, filters: we show you the essentials before we leave.

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.
Good habits, once the unit is in place

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.
