Installation of a Panasonic wall-mounted heat pump in Rosemont–La Petite-Patrie

A neat integration above a patio door in a Montreal kitchen

At AirGreen , we optimize each HVAC installation to combine performance, comfort, and aesthetics. In this Rosemont–La Petite-Patrie (Montreal) home, we installed a Panasonic wall-mounted heat pump positioned above a patio door , in the heart of the kitchen. The goal: to efficiently cool the main living space in the summer, ensure stable heating during the off-seasons, and reduce overall electricity consumption—without compromising the room's ergonomics.

Client context and needs

The condo features a kitchen area adjacent to the dining room, with direct access to a rear terrace. The typical Montreal layout (patio door, standard ceiling, tall cabinets on the right side) limited the potential locations for the interior headboard. The client was looking for:

• Fast and consistent summer comfort , even during heat waves.

• A quiet heating supplement in spring and fall.

• A discreet and clean integration into a kitchen used daily.

• A reliable solution eligible for grant programs when equipment and performance allow.

Choosing equipment: why Panasonic

The Panasonic brand is renowned for the quality of its motors and the optimization of its control electronics, two key elements for temperature stability and energy efficiency . In residential applications, their indoor units are distinguished by:

• Precise and modulated blowing , useful for avoiding direct air currents in food preparation areas.

• Reduced noise levels , appreciated in an open kitchen where people talk, cook and entertain.

• Accessible filters promoting regular HVAC maintenance , crucial in the kitchen environment (greasy particles, steam).

In this project, the Panasonic wall-mounted heat pump covers the kitchen and adjacent space, with sufficient airflow to circulate the entire area without obstructing traffic around the patio door.

AirGreen installation constraints and technical responses

1) Mounting high above a patio door

Installation above an opening requires careful planning : solid mounting in the frame, respect for upper clearances for air intake and free access to the shutter . We have:

• Checked the fixing axis on a suitable lintel and reinforced the support if necessary.

• Maintained sufficient ceiling clearance behind the upper intake to preserve cooling mode performance and thermal sensor stability.

• Position the unit to avoid air recirculation against the ceiling, thus limiting hot/cold stratification.

2) Proximity of cabinets and airflow management

The presence of wall units on the right side requires fine-tuning the sweep to ensure that the air does not directly hit the cabinets. The orientation of the vanes and the fan speed have been set to maximize diffusion towards the dining room and limit the impact on the cooking zones.

3) Short and discreet refrigeration path

The installation near the exterior allowed for a clean side wall crossing , with a curvature radius respected for the insulated copper connections. Inside, the routing remains invisible ; outside, the white capping (UV protection sheath) ensures watertightness and the architectural finish.

4) Drainage of condensate by gravity

The unit, placed at a high point , allows gravity evacuation of the drain—a reliable and silent solution that avoids the need for an additional pump. The pipe is continuously sloped , insulated to prevent any parasitic condensation and protected when passing through the wall.

5) Dedicated power supply and safety

The heat pump is connected to a dedicated circuit (circuit breaker sized according to the model's nameplate) and an external disconnect switch has been provided near the condenser. This standardized diagram facilitates maintenance work and secures the installation.

Sizing and comfort: our approach

Even when a photo does not reveal the identification plate, our sizing is always based on a load calculation (volume, internal inputs, sunshine, infiltration). In a kitchen, variable thermal inputs (oven, stove, occupants) require a modulation margin . The inverter technology of the Panasonic wall-mounted heat pump responds precisely to these variations, adjusting the power to stabilize the temperature smoothly, with a measured impact on the electricity bill .

Good practices in a kitchen

• Filtration and hygiene : cleaning of filters more frequently than elsewhere (during periods of intensive use).

• Flow direction : avoid blowing directly onto the cooking areas or the table; favor a wide sweep towards the living space.

• Annual maintenance : complete HVAC maintenance (pressure, temperature, tightening, exchanger cleanliness, drain test) maintains seasonal performance and preserves the warranty .

• Clearances : Respect the top and side clearances around the inner head to avoid performance losses and suction noise.

Result: comfort, silence and clean finish

The Panasonic unit fits perfectly above the patio door, invisible in everyday life but effective from the first warm weather. The blower covers the kitchen and dining room; the temperature remains uniform , even when the door is repeatedly opened. The reduced noise level allows you to cook, chat or work without disturbance.

Grants and eligibility (point of attention)

Many Panasonic wall-mounted heat pumps meet the eligibility criteria for the Montreal, Laval, Longueuil, North Shore and South Shore programs, when their certified performance and cold weather operating range allow it. We systematically check:

• Certification numbers (AHRI/NRCan).

• The required seasonal outputs (heating and air conditioning).

• The low temperature operating range specified by the manufacturer.

When the chosen device meets the scales, our team assists the customer in preparing the files and proof of installation (detailed invoice, model numbers, installation photos, etc.).

Operating tips to maximize savings

1. Stable setpoint : maintaining a regular setpoint avoids unnecessary power calls.

2. Reasonable dehumidification mode : use it in heavy weather, not continuously.

3. Interior doors : leave them ajar to improve distribution to adjacent rooms.

4. Periodic cleaning : filters and facade; plan annual professional maintenance to maintain performance and air quality.
