Installation of a Sharp (R-32) wall-mounted heat pump in Chomedey (Laval)

A neat installation in a courtyard equipped with a swimming pool: four-season comfort and exemplary integration

Residency context and objectives

At AirGreen , we are working in a residential area of ​​Chomedey (Laval) , where the backyard already houses technical equipment (pool treatment, outdoor power supply). The challenge: installing a new generation Sharp R-32 wall-mounted heat pump while maintaining safety clearances, controlling acoustics and ensuring durability in the face of humidity and splashes related to the pool.

Why choose a Sharp R-32?

  • Inverter technology for stable comfort in summer and winter.

  • R-32 (A2L) fluid : better performance and reduced global warming potential compared to R-410A.

  • Extreme cold operating range on recent series, ideal for the Montreal and Laval region.

  • Simplified HVAC maintenance thanks to a clear architecture and direct access to components.

Our installation approach: precision, cleanliness and safety

Outdoor location: take into account the swimming pool and surrounding areas

  • Galvanized wall bracket at the right height to clear the slab and facilitate winter snow removal.

  • Direct the air discharge away from the fence corner to avoid recirculation and moisture projection against the siding.

  • Integrated vibration damper between the support pads and the device to limit transmission to the facing.

  • Management of the chlorinated environment : stainless steel screws and hydrophobic treatment of the fins recommended during maintenance, because the proximity of a swimming pool increases the risk of corrosion.

Power supply and electrical protection

  • External disconnect box in close proximity to the unit for maintenance safety.

  • Wiring in conduit to the power point; checking the rating and dedicated circuit breaker according to the Sharp's current ratings.

  • Controlled grounding ; protected routing to avoid contact with runoff water from the terrace or swimming pool.

Refrigerant connections and finishing

  • Short and direct route from the inside head: gentle bends to respect the radii of curvature, continuous isolation of the two lines.

  • Clean exterior capping along the foundation, with waterproof transitions to prevent water infiltration.

  • Single hole with sleeve and vapor barrier inside; sealed with UV-compatible exterior mastic.

  • Condensate drain with gravity slope to prevent backflow near pool equipment and the passageway.

AirGreen Technical Procedure

  1. Thermal survey and validation of clearances, including distances from the fence and technical boxes.

  2. Anchoring the wall bracket to the structure, wedging and laser leveling.

  3. Nitrogen brazing , leak testing, deep vacuum to ensure a dry circuit.

  4. Charging , checking parameters (overheating, subcooling), testing in cold then in heating .

  5. Setting silent modes and time programming adapted to household habits.

  6. **Provision of an HVAC maintenance guide and an annual monitoring schedule.


Sizing and expected performance

  • Recommended capacity : 9,000 to 18,000 BTU for standard living areas; adjustment depending on insulation, orientation and internal inputs.

  • High seasonal efficiencies on the Sharp R-32 range, promoting tangible energy savings in air conditioning costs and mid-season heating support.

  • Controlled acoustics thanks to Quiet mode and wall-mounted installation that keeps vibrations away from the floor.

Integration details visible on this achievement

  • Rigid wall support , clearance under the appliance for defrosting in winter.

  • External disconnect box placed within easy reach, neat cable routing in the ducts.

  • Low capping along the foundation, short sections of refrigeration connections to reduce pressure losses.

  • Water management : routing of condensates away from swimming pool equipment and pedestrian areas.

Instructions for use and maintenance

  • Clean the inner head filters every 4 to 8 weeks during use.

  • Maintain clear clearance in front of the unit, especially in winter (snow, ice).

  • Program stable setpoints (reasonable day/night differences) to maximize inverter efficiency.

  • Schedule annual maintenance : cleaning batteries, checking pressures, checking electrical connections and line insulation.

  • Near a swimming pool, gently rinse the outdoor battery with clean water at the beginning and end of the season to limit deposits.

Safety and Compliance (R-32, A2L)

  • R-32 fluid is classified A2L (low flammability). Our certified technicians apply the required ventilation, detection and sealing rules, which guarantees a safe HVAC installation that complies with the standards in force in Quebec .

Grants and administrative support

New-generation, high-efficiency wall-mounted heat pumps may be eligible for financial assistance depending on active programs. We assist our clients in Montreal, Laval, Longueuil, the North Shore, and the South Shore to verify eligibility (cold weather performance ranges, certifications) and prepare the application.

Result: comfort, silence and preserved space

  • Stable thermal comfort in the service area, in summer and in the off-season.

  • Reduced visual footprint despite the presence of pool equipment.

  • Better controlled operating costs thanks to continuous modulation and high-performance R-32 .


Why entrust your project to AirGreen?

  • Mastery of residential contexts with existing equipment (swimming pool, spa, electrical sheds).

  • Strict compliance with clearances , acoustics and standards .

  • Responsive after-sales service : maintenance, parts, optimization of seasonal settings.

  • Intervention throughout Montreal, Laval, Longueuil, North Shore, South Shore with tailor-made and sustainable HVAC solutions.
