Stable comfort in the dining room, without compromising on aesthetics or efficiency
At AirGreen , we installed a Fujitsu wall-mounted heat pump – Altair range (R-32) in a single-family home in Brossard . The owner's goal: to moderate the dining room open to the kitchen and living room, a space often hot in summer and cooler in winter because of the large window and an old electric baseboard heater as a backup. A quiet , economical and discreet solution was needed, capable of providing consistent comfort during meals while blending perfectly into the decor.
Context of the room and choice of location
The dining room features:
-
A side window facing the backyard, generating significant solar gain at the end of the day.
-
A standard ceiling and a pendant light above the table.
-
A clear side wall is the only suitable location for directing airflow along the room without blowing directly onto the guests.
We positioned the wall head near the upper corner, above the window lintel , to benefit from optimal air intake and longitudinal diffusion towards the table. This configuration avoids drafty areas and maximizes thermal mixing with the rest of the ground floor.
Why Fujitsu – Altair range (R-32)
Fujitsu 's Altair (R-32) family meets today's residential requirements: high seasonal efficiency , precise inverter control, reliable components and very low noise levels both indoors and outdoors. For a dining room, these advantages are decisive:
-
Fine airflow : adjustable motorized shutters, ideal for directing air along the wall and avoiding a direct flow onto the table.
-
Energy efficiency : Inverter compressor modulating power to maintain the target temperature with limited consumption.
-
R-32 refrigerant : lower climate impact and better volumetric performance than R-410A generation.
-
Simplified maintenance : easy-access filters for quick HVAC maintenance by our teams.
Desired result: stable comfort in summer and winter, low noise levels during meals and simple visual integration .
Technical details of the AirGreen installation
Chosen configuration
-
Type : single-zone wall-mounted heat pump ( mini-split ).
-
Brand / range : Fujitsu Altair (R-32) .
-
Capacity : sized for the dining room area + adjacent area (BTU selection based on a load calculation and losses from the bay window).
-
Power supply : dedicated 230 V circuit with external disconnector and panel protection.
-
Condensates : gravity drainage to the outside (no pump required), protected against frost.
-
Refrigeration lines : short route (≈ 2.5 to 3.5 m ), direct crossing of the perimeter wall behind the unit.
-
Finish : white capping matching the walls; waterproof sealing of the drilling with vapor barrier and insulation.
-
Outdoor unit : installed on wall brackets in the backyard, clear of snow and debris, with silent blocks to limit vibrations.
Checks and commissioning
-
Nitrogen test and leak test .
-
Vacuum pushed to the required level and stabilization.
-
Adjust the airflow and the angle of the flaps to avoid drafts on the table.
-
Electrical check (polarity, tightening, currents).
-
Customer training : usage instructions, seasonal modes, filter maintenance.
Aesthetic integration and acoustic comfort
In a dining room, aesthetics count. The white unit with soft lines blends in with the light woodwork and furniture. The wiring is invisible , the caps are aligned, and the drilling has been carefully done to leave no visible marks. In operation, the low speed is sufficient to maintain the setpoint: minimal noise , perfect for peaceful meals or evenings with guests.
Smart management with existing systems
The house still had an electric baseboard heater under the window. We recommended:
-
To use the heat pump as the main source of heating during mid-season and mild winters, in order to reduce the electricity bill.
-
Keep the baseboard as a backup during very cold weather or as a safety feature in the event of a prolonged absence.
This dual-energy electric strategy promotes savings while ensuring simple redundancy .
Energy savings and potential subsidies
Recent R-32 wall-mounted heat pumps , when properly sized and installed, achieve high seasonal efficiencies . Depending on the exact model selected and its low-temperature heating performance, the project may meet the criteria of current Quebec grant programs . Our team supports each client to:
-
Check eligibility (performance, certification, installation by licensed contractor).
-
Prepare supporting documents (detailed invoices, serial numbers, installation photos).
-
Advise on maintenance to maintain performance over the years.
Good practices adopted on this project
-
Optimized installation height for efficient air mixing without direct blowing onto occupants.
-
Reduced connection length to minimize pressure losses and the risk of refrigerant noise.
-
Condensate drainage by gravity , more reliable and maintenance-free than a pump.
-
Standard clearances around the outdoor unit for free air flow and efficient defrosting.
-
Careful finishing (capping, sealing, alignments) for a discreet and durable finish.
AirGreen Tips for a Comfortable Dining Room All Year Round
-
Instructions : aim for 22–23°C in summer and 21°C in winter in living areas; adjust according to sunlight.
-
Shutters : direct the air along the walls or towards the ceiling to avoid drafts on the guests.
-
Filtration : Vacuum filters every 4 to 8 weeks ; wash with warm water if necessary.
-
Open doors : Leave the door half-open to the kitchen/living room to balance the temperature.
-
HVAC maintenance : annual visit recommended (exchanger cleaning, condensate check, electrical checks).
