Four-season comfort in a Laval condo: a MultiZone installation designed for silence, efficiency and co-ownership
Located in the heart of Chomedey (Laval) , this project has a clear objective: to offer stable and economical comfort in a condo with a balcony, without compromising aesthetics or co-ownership rules. At AirGreen , we recommend HVAC solutions adapted to urban buildings. Here, the Fujitsu Halcyon HFI MultiZone heat pump stands out as a coherent choice: proven efficiency, discreet operation, zone flexibility and perfect integration into a brick environment with a tiled balcony.
Context: one condo, several comfort zones
The owner wants to air condition and heat the main living areas— the living room open to the kitchen and the master bedroom —with the option of adding a third zone later. In a condominium building, the priorities are:
-
Silence on the balcony and inside, so as not to disturb the neighbors and respect the regulations.
-
Energy efficiency in summer and winter to reduce operating costs.
-
Clean integration of refrigeration and electrical paths, with an HVAC installation that blends in with the building's brick facade .
-
Respect for mechanical clearances and air circulation, essential for the longevity of the equipment.
The equipment selected: Fujitsu Halcyon HFI MultiZone
We are installing a MultiZone heat pump from Fujitsu 's Halcyon HFI range. Key points:
-
Typical capacities of 18,000 to 24,000 BTU for the selected MultiZone outdoor unit (sizing adjusted after load calculations).
-
High seasonal efficiencies : a competitive SEER for summer air conditioning, and an HSPF2 allowing significant heating savings during the Laval winter.
-
Cold weather performance down to -25°C , highly sought after for Greater Montreal .
-
Compatibility with several types of indoor units: wall heads , cassettes or floor consoles , which allows each zone to be adapted to its use.
-
Reduced noise level on the condenser and evaporator sides, ideal for co-ownership.
Expected result: consistent comfort, fine modulation of flow rates, and stable cycles that protect the energy bill.
Outdoor installation: stability, silence and easy maintenance
The outdoor unit is placed on a raised galvanized steel support , cushioned by anti-vibration pads . This configuration provides several benefits:
-
Clearance under the equipment to drain defrost water in winter and facilitate cleaning;
-
Reduction of vibrations transmitted to the balcony slab;
-
Easy access for periodic maintenance (cleaning coils, inspecting connections).
We respect the lateral and frontal clearances provided by the manufacturer for good airflow and avoid nearby obstacles (railings, perpendicular walls, sliding doors). The passage of the refrigeration lines is done through the brick wall with a waterproof drilling , caulked and capped on the outside for a clean and durable finish.
Refrigeration path and condensate management: cleanliness and reliability
The route of insulated copper pipes and communication cables is short and direct from the balcony to the rooms served. In a condo, this minimizes:
-
Pressure losses (better efficiency).
-
The risks of fluid noise (whistling) in lightweight partitions.
-
Visual impact inside and out.
Condensate management : the wall-mounted head on the living room side benefits from a discreet gravity drain , while the bedroom – far from the load-bearing wall – incorporates a small soundproofed lifting pump , installed in a formwork accessible for annual maintenance. This configuration guarantees safe drainage without impact on common areas or infiltration.
Electricity and compliance
The outdoor unit is powered via a dedicated circuit with a circuit breaker sized according to the nameplate and a nearby service switch . We install a matching electrical trunking for neat integration into the brick wall. The communication and power connections for the indoor heads follow the same route to reduce drilling and simplify maintenance .
Commissioning steps
-
Deep vacuum on the refrigeration lines to the threshold recommended by the manufacturer, then leak test .
-
Checking loads (adjustment as needed according to actual lengths, in accordance with Fujitsu tables).
-
Configuration of remote controls and testing of modes (cooling, heating, dehumidification, ventilation).
-
Functional measurements : blown temperatures, intensities, communication statuses, parasitic noises.
-
Provision of a user guide and HVAC maintenance advice adapted to living in a condominium.
Constraints addressed and solutions applied
Tiled balcony and limited space
-
Choice of a raised support with a reduced footprint, without intrusive anchoring, to preserve the waterproofing of the balcony.
-
Orientation of the blower vent and distances respected to prevent recycling of hot/cold air and limit fogging on the sliding door.
Brick facade
-
Limited drilling and clean sealing; UV and frost resistant caps and capping .
-
Careful path to avoid altering the aesthetics of the facade visible from the street.
Co-ownership regulations
-
Technical file submitted to the union: product sheet , noise levels , clearances , illustration of the implementation plan .
-
Annual preventive maintenance commitment to maintain performance and control noise.
Observed results
-
Rapid cooling of the living room-kitchen during hot weather, with modulated airflow to avoid direct drafts.
-
Stable heating during the off-season and in winter, particularly appreciated in the bedroom where the night-time setting is maintained without over-oscillations.
-
Low exterior noise : the condenser, mounted on shock absorbers, remains discreet on the balcony.
-
Controlled consumption thanks to the inverter and the good power/needs match.
HVAC Maintenance and Longevity
To maintain performance:
-
Clean the filters of the interior heads every 2 to 3 months during periods of intensive use.
-
Gentle washing of the outdoor coil in spring and fall, checking the condensate drains .
-
Annual inspection by AirGreen: pressures, currents, connections, condition of insulation and capping, updating of parameters if necessary.
Regular maintenance prevents overconsumption, extends the life of the compressor and reduces the risk of abnormal noise.
Grants and Eligibility
Heat pumps in this range, with their certified performance and cold resistance, are generally eligible for programs in effect in Quebec. We assist our clients in preparing proof of installation , AHRI numbers , and required supporting documents . Our team also explains how priority heating use can maximize energy savings and strengthen the case.
Practical advice for condominiums in Laval, Montreal and the South/North Shore
-
Anticipate routes : the shorter and more direct the lines, the better the yields and discretion.
-
Consider defrosting : provide a winter water drain (not harmful to neighbors under the balcony). If necessary, add a retention tray with a directed outlet.
-
Choose units with low noise levels and anti-vibration mounts .
-
Validate the union regulations : color of the capping, position of the condenser, intervention times.
-
Schedule maintenance upon installation to protect the warranty and performance season after season.
