Impeccable interior installation, designed for comfort and efficiency in a Montreal plex
At AirGreen , we have just installed a Zephyr wall-mounted heat pump (R-32) in a home in the Villeray–Saint-Michel–Parc-Extension sector of Montreal. The project had three clear objectives: ensuring four-season comfort , ensuring careful interior integration and optimizing energy efficiency in a partially open-plan living space.
Context and sizing: a system well calibrated for space
The accommodation consists of a main living room that connects to an office area and a corridor to the bedrooms. After recording the surfaces, solar gains and occupancy habits, we retained a nominal capacity of 12,000 BTU for this wall-mounted head - an ideal balance between cooling speed in summer and stable heating at low temperatures in mid-season and early winter. The Zephyr's inverter technology allows for fine modulation of the power , avoiding on/off cycles and reducing electricity consumption.
Choice of location: priority to air diffusion and aesthetics
The indoor unit is installed at the top of the wall , centered on the main section, with a ceiling clearance respecting the manufacturer's recommendations so as not to disrupt the suction. The proximity of a circulation return ensures even distribution of conditioned air to adjacent areas.
Key points of this positioning:
-
Installation height optimized to promote natural stratification (hot air at the top, cool air at the bottom) and the range of the motorized shutter .
-
Sufficient lateral clearance for maintenance and free oscillation of the fins.
-
Invisible connections : the passage of the refrigeration connections and the drain is hidden behind the appliance , preserving a minimalist aesthetic.
What the Zephyr R-32 series changes in a Montreal home
Zephyr's R-32 range offers high seasonal efficiencies and reduced global warming potential compared to R-410A. In everyday use, this translates to:
-
Controlled consumption thanks to a competitive SEER/HSPF for the residential segment;
-
Discreet indoor noise level , ideal for teleworking or relaxation;
-
Flexible control (remote control, fine settings, timer, night and dehumidification modes).
Combined with a rigorous HVAC installation , this architecture guarantees advantageous operating costs and stable comfort throughout the seasons.
The AirGreen method: clear steps and lasting results
Our certified installers follow a proven protocol, which we adapt to each Montreal building, whether plexes, condos or single-family homes.
-
Tracing and leveling
Use a template, laser level, and mark the uprights for a perfectly anchored support plate . The goal is to eliminate any risk of vibration and ensure flatness for condensate drainage. -
Drilling and routing of connections
Through-hole drilling with a slight outward slope for reliable gravity drainage . We protect the insulation from the connections and provide a copper-friendly bend radius to avoid micro-stresses. -
Refrigeration connections
Clean flares, dynamometer-controlled tightening torques , nitrogen leak tests and deep vacuum draw to the level required by the equipment standard. -
Dedicated power supply
Checking the circuit's conformity (size, circuit breaker, grounding). The communication cabling is routed away from any source of electromagnetic noise. -
Instrumented commissioning
Overheating/subcooling checks according to daily conditions, verification of blowing temperatures and validation of heating/cooling/dehumidification modes .
Integration details visible on this interior installation
-
Smooth Zephyr front panel with discreet digital display : immediate reading of setpoint and status feedback.
-
Near-corner placement : The flow is oriented to sweep the room without creating dead zones or blowing directly onto occupants.
-
Clean finishes : no visible cables, no unnecessary interior ducts, walls redone and cleaned after fixing.
-
Gravity drain : silent, reliable, without pump; slope checked over the entire length up to the external discharge point.
Result obtained: comfort, silence and humidity control
Upon commissioning, the measured blowing indicates a rapid drop in ambient temperature in air conditioning mode, with stabilized relative humidity thanks to Dry mode when required. In mid-season, the inverter modulation maintains a mild and regular interior temperature without jolts. Occupants emphasize the unit's acoustic discretion and ease of control.
Best practices for maximizing savings
-
Realistic guidelines : 23–24°C in summer, 20–21°C in winter; avoid sudden changes that increase consumption.
-
Open doors to the rooms to be served to take advantage of the sweeping effect.
-
Auto/Heat/Cool mode used wisely: Auto for modulation, Cool during heat peaks, Heat as needed in mid-season.
-
Clean filters every 4 to 8 weeks depending on usage; a clean filter improves airflow and reduces consumption .
-
Clearance under the unit: leave the area free so as not to disturb the air jet .
HVAC Maintenance: The Difference Between “Working” and “Performing”
Annual HVAC maintenance extends lifespan and maintains advertised performance:
-
Disassembly and cleaning of the internal battery and the condensate tray;
-
Gentle disinfection of exchange surfaces to limit pollen and dust;
-
Electrical check (terminals, currents, insulation) and refrigeration check (signs of leakage, pressures under load);
-
Update of user settings (scanning, speed, eco settings).
AirGreen maintenance contracts simplify planning and provide useful documentary tracking for warranty .
