Optimize a Montreal bedroom without affecting the existing charm: we integrate a Sharp wall-mounted head above the window-curtain corner for stable, quiet, and economical comfort all year round.
Context: a room that must remain calm, cool in summer and warm in winter
In an apartment in Villeray–Saint-Michel–Parc-Extension , the client wishes to improve the comfort of a bedroom/office facing the courtyard. The room has a ceiling fan , a sliding window with an exposed rod, and light furniture. The expressed needs: reduce summer overheating, stabilize the temperature on winter nights, reduce noise and consumption compared to a portable device.
Our recommendation is based on a Sharp R-32 heat pump from the recent wall-mounted range, chosen for its efficiency in both air conditioning and heating, its discreet operation and the quality of its air treatment (Plasmacluster technology, the brand's signature).
Why choose the Sharp brand for a bedroom in Montreal?
-
R-32 : reduced charge, better heat transfer and smaller footprint than an older refrigerant.
-
Inverter modulation : the device adjusts precisely to the actual load, avoids ON/OFF cycles, lowers noise and reduces consumption .
-
Heating in cold weather : maintaining capacity at low temperatures, advantageous for Montreal, Laval, Longueuil, North Shore, South Shore .
-
Soft diffusion : adjustable fins and wide flows that prevent direct air currents onto the bed or workstation.
-
Air quality : Integrated purification technology (Sharp trademark) provides added value for a restful room.
Overall objective: 4-season comfort with careful HVAC installation , without compromising on the aesthetics of the wall.
Precise location: side wall, top of wall, close to the carpentry
The chosen position — top of wall , rod and window side — has several technical advantages:
-
Controlled stratification : near the ceiling, the device mixes hot and cold air, equalizing the temperature up to the sleeping surface.
-
Short path to the exterior : the adjoining facade allows discreet drilling and short refrigeration connections , a guarantee of efficiency.
-
Comfort Protection : The blowing direction is set along the wall to avoid direct air onto the bed/desk area while sweeping the room.
-
Maintenance access : hood and filters remain accessible despite the rod; we guarantee sufficient clearance for periodic cleaning.
Salient installation details
-
Wall plate : installed by laser, anchors adapted to the support to prevent any vibration.
-
Drilling of Ø ~65 mm sloping outwards for gravity drainage of condensates . When geometry requires it, we integrate a silent mini-pump.
-
Insulated refrigeration connections and communication wiring covered in white to match the joinery; bending radius respected to protect the copper.
-
Deep vacuum < 500 microns; leak test before opening the valves; additional charge according to actual length.
-
Dedicated power supply from the panel, circuit breaker of the prescribed rating and standardized cable, with clear identification for the owner.
-
Ceiling fan management : instructions explained to the customer (low mode in summer, stop in winter during defrosting) to support the heat pump without creating a feeling of draft.
Sizing and expected performance
The choice in BTU/h is established on the basis of:
-
of the useful surface area ,
-
orientation and solar input ,
-
the type of envelope (sliding window, seals, curtains),
-
of use (sleep, teleworking).
With inverter modulation, the device maintains a stable refresh rate at low speeds, avoiding temperature fluctuations. In heating, the regulation ensures a gentle and constant nighttime setpoint , beneficial for sleep quality.
Everyday comfort
-
Silent operation thanks to low speeds.
-
Even diffusion by wall sweeping which covers the volume, even with drawn curtains.
-
Improved air quality through brand filtration and ionization.
AirGreen Best Practices (and Mistakes to Avoid)
To do:
-
Leave 5 to 10 cm of clearance above and on the sides for suction.
-
Adjust the fins so that the flow follows the wall and does not hit the bedding .
-
Check the drain slope ≥ 1% and insulate properly to prevent condensation on the paint.
To avoid:
-
Block the air return with bulky curtains; provide a rod offset if necessary.
-
Position a desk directly in line with the blowing at short distance.
-
Let the dust accumulate: simple, regular HVAC maintenance maintains efficiency.
AirGreen Installation Process
-
Technical visit : taking measurements, studying the route, electrical verification.
-
Preparation : surface protection, covering furniture, laser markings.
-
Drilling & installation : fixing, passage of connections, connections, vacuum drawing and testing.
-
Commissioning : setting up modes, explanations of use, delivery of documents.
-
Follow-up : assistance with applicable grants and maintenance reminder.
Grants and Eligibility
High-efficiency wall-mounted heat pumps operating on R-32 and suitable for extreme cold are generally eligible for assistance programs in Greater Montreal ( Montreal, Laval, Longueuil, North Shore, South Shore ), subject to conditions (certified model, installation by qualified contractors, audit/supporting documents). We take care of preparing the files and explain the supporting series/model document required by the organizations.
Maintenance recommended for longevity
-
FILTERS : rinse every 4 to 6 weeks during use.
-
Annual inspection : pressures, connections, condition of insulation, drain test, evaporator cleaning.
-
EXTERIOR (condenser): clear fins, check support, check defrost cycle.
-
OPTIMIZATION : time programming, eco-management during the day, maintaining a reasonable gap between summer/winter settings to maximize SEER/SCOP.
Result: comfort, discretion and savings
The room gets a consistent temperature and low noise , the energy bill is lower than with a portable unit, and the wall-mounted installation fits in with the room's style. The whole thing is ready for serious after-sales service : usage tips, reminders, and AirGreen's availability if needed.
