The kitchen can finally breathe: a discreet Sharp wall-mounted heat pump , installed above the window, ensures precise comfort in summer and winter without encroaching on the preparation space. Here's how we designed and built this clean and sustainable HVAC installation in a typical Montreal plex.
Controlled comfort in a demanding kitchen
Between the heat of the stove, steam, and odors, a kitchen requires precise regulation and even air distribution . Our team installed a Sharp ZU1 series ( R-32 refrigerant) here, chosen for its stable modulation at low speeds and its wide flow that covers the entire room without drafts, even when the sink and countertop are occupied.
Housing context and head location
-
Apartment/plex in Rosemont–La Petite-Patrie with tree-lined backyard and balcony.
-
Wall head positioned high on the lintel, centered on the window to sweep the room and avoid the obstruction of cabinets.
-
Clearance must be maintained under the ceiling molding to ensure air intake from above and the shutter can open freely.
-
Infrared control accessible near the kitchen entrance.
Refrigeration path and condensate management
-
Exit to the right of the unit , clean wall crossing, dark capping matching the interior cladding for aesthetic integration .
-
Gravity drainage with controlled slope towards the outside, avoiding the use of a pump in this noise-sensitive area.
-
Short total length of refrigeration lines (~2–3 m) : minimized losses, optimized efficiency .
Outdoor condenser and winter protection
-
Sharp condenser mounted on wall brackets at the rear, above snow level and clear of balcony traffic lanes.
-
Installation with anti-vibration silent blocks , anti-icing loop at the drain and snow guard provided if necessary.
-
Rear clearance and clear area in front of the unit in accordance with good practices to facilitate HVAC maintenance .
Why the Sharp ZU1 series for a kitchen?
Performance & comfort
-
Highly responsive inverter compressor: maintains a stable temperature despite heat peaks associated with cooking.
-
Low GWP R-32 , improved seasonal efficiency and reduced fluid charges.
-
Regular dehumidification mode to dry the air during extended cooking sessions.
Silence and hygiene
-
Low noise level at low speed: conversation and calls without disturbance.
-
Easy-access filters above the window: clean in minutes, essential in the kitchen.
Montreal winter taken care of
-
Reliable performance in cold weather , sufficient to support mid-season heating and relieve the main system.
-
Effective defrosting limiting heating shutdowns .
Our AirGreen methodology in Rosemont
Taking measurements and structural validation
We checked the structure above the window , located the studs and the free space under the cornice, then confirmed the absence of electrical elements in the drilling area.
Clean drilling and sealing
-
Single core drilling with controlled slope for all three pipes (liquid, gas, drain).
-
Insulated bulkhead , air barrier foam and exterior sealant finish to prevent any water or air infiltration.
Connections and commissioning
-
Flares calibrated to exact torque, pressurized nitrogen for leak testing, then high vacuum < 500 microns.
-
Checking the exchange surfaces and air flow with anemometer; setting the Auto mode adapted to the thermal loads of the kitchen.
Result: immediate comfort, reduced bill
-
Rapid cooling of the kitchen/living room hot spot, controlled noise and optimized consumption thanks to the short length of lines.
-
Simplified maintenance : accessible filters and planned clearances.
-
Eligible, depending on the energy profile of the home and the programs in force, for incentives for efficient heat pumps applicable in Montreal, Laval, Longueuil, North Shore and South Shore .
Expert advice for a kitchen like yours
Good user reflexes
-
Leave the automatic speed for long cooking: the machine modulates without creating a cold blast.
-
Use the dehumidification mode during large boiling periods to maintain a dry atmosphere .
Essential HVAC Maintenance
-
Vacuum filters every 4 to 6 weeks in the kitchen; a dirty filter lowers the SEER and increases noise.
-
Clear the outdoor condenser after each storm and in the spring.
Common mistakes to avoid
-
Place the head too close to the ceiling or wedged between cupboards: the suction becomes clogged and performance drops.
-
Condensate pump unnecessary : if a gravity slope is possible, favor silent simplicity .
-
Too long lines in a small home: unnecessary losses and costs.
