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.
