Installation of a Sharp (R-32 wall-mounted range, Eco Inverter) wall-mounted heat pump in Verdun

Four-season comfort in a Verdun condo: a compact, stable installation designed to last

At AirGreen , we design each HVAC installation based on the reality of the location. In Verdun , in a recent condo building bordered by bike paths and riverbanks, we installed a Sharp wall-mounted heat pump – R-32 wall-mounted range (Eco Inverter) . The goal: to provide reliable, quiet and economical heating and cooling , without compromising the aesthetics of the balcony or traffic near the patio door .

Project context: urban condo, narrow balcony, neighborhood constraints

The apartment is located on an intermediate floor with a balcony covered with rubber tiles and a low threshold for the patio door. The constraints were clear:

• Limited space and frequent passage in front of the door;

• Compliance with co-ownership rules : noise level, clearances, visual cleanliness;

• Vibration protection to prevent transmission to the floating floor of the living room;

• Easy maintenance (winter defrosting, access to connections, cleaning of the condenser).

We therefore opted for a lateral and raised installation, against the wall, away from passage areas. This positioning preserves the air flow and reduces the recirculation effect when the wind blows along the facade.

Why the Sharp R-32 (Eco Inverter) wall-mounted range in Verdun?

The Sharp wall-mounted family (Eco Inverter, R-32 refrigerant) is appreciated for:

• High efficiency in heating and air conditioning thanks to the inverter compressor ;

• R-32 refrigerant , more energy efficient and with lower global warming potential than R-410A;

• Quiet operation suitable for condominiums;

• Filtration quality and air treatments specific to the brand;

• Stability at low temperatures typical of Greater Montreal, with performance maintained during freezing periods.

From a budgetary perspective, this range provides excellent value for money , while preparing the home for recent standards and the development of aid programs linked to high-performance equipment.

Installation details: precision, stability and safety

• Equipment type : Sharp wall-mounted heat pump – R-32 wall-mounted range (Eco Inverter).

• Location : Condo balcony in Verdun, along the wall adjacent to the patio door.

• Support : Raised aluminum/steel frame with blue anti-vibration feet under each pad — mechanical stability reduces structure-borne noise and protects the balcony covering.

• Clearances : optimized distance on the wall side and front of the unit to promote heat exchange and defrosting.

• Vibration management : controlled tightening of fasteners, resilient buffers and chassis balancing.

• Condensate drainage : gravity drain guided along a support upright ; continuous slope to prevent water pockets and freezing; protected end for controlled dripping .

• Refrigeration path : continuously insulated and sheathed connections; curvature radius respected to preserve the load and pressures; wall crossing sealed on the interior side (air and water tightness).

• Electrical : dedicated power supply with compliant circuit breaker and nearby connection box, respecting clearances and intervention safety .

• Finish : capping specific to the right of way; stainless steel screws; exposed parts protected against bad weather.

This raised mounting promotes uniform ventilation of the condenser , limits the accumulation of debris around the base and facilitates maintenance . The chosen height prevents accidental impacts when opening/closing the patio door and frees up the passage area.

AirGreen Methodology: Invisible Quality, Visible Results

Each installation is carried out according to a rigorous protocol:

1. Checking the support loads and anchors : controlled tightening torque, flatness, leveling.

2. Flaring and brazing carried out with calibrated tools; deep vacuum drawing until stabilization; leak test.

3. System setup and functional tests (cold/warm start, current measurement, overheating/subcooling).

4. Acoustic control : listening at low and high speeds, checking for parasitic vibrations .

5. Submission of an installation report and usage advice to the customer.

Site challenges and solutions implemented

• Immediate proximity to the threshold : we have reduced the projected depth in the walking area with a compact support;

• Exposed balcony : the raised frame allows for better evacuation of condensates and limits the accumulation of dust on the floor;

• Neighborhood : selection of a silent night mode and orientation of the air flow to minimize noise disturbance .

Benefits for the occupant

• Four-season comfort : stable heating during the off-season and in cold weather, efficient air conditioning during Montreal heat waves;

• Energy savings : Inverter modulation and efficient R-32 ;

• Discretion : low noise level, reduced vibrations ;

• Simplified maintenance : direct access to the condenser, clearances provided for cleaning and inspections.

Best practices for condominium balconies (Verdun, Montreal, Laval, Longueuil, North Shore, South Shore)

• Respect the clearances around the condenser (front and sides).

• Favor gravity drainage of the drain with a continuous slope; consider a heating cable if the balcony is very exposed in winter.

• Install anti-vibration pads under the supports and periodically tighten the screws (annual inspection).

• Clean the condenser grille at the beginning and end of the season to maintain efficiency .

• Schedule HVAC maintenance : Annual maintenance extends lifespan and maintains performance.

Grants and Compliance

High-efficiency wall-mounted heat pumps using R-32 are generally eligible for assistance programs when seasonal performance and low temperature criteria are met. We support our clients in Montreal, Laval, Longueuil, North Shore and South Shore to verify eligibility , prepare documents and optimize compliance (noise, clearances, electrical and co-ownership requirements).

Why entrust your project to AirGreen?

• Recognized HVAC specialists in Greater Montreal for wall-mounted and multi-zone heat pumps;

• Clean and sustainable installations , tested and documented;

• After-sales service : maintenance reminders, rapid troubleshooting, original parts;

• Advisory approach : sizing, choice of location, co-ownership rules, aesthetics and acoustics .

Verdict: A compact integration that maximizes comfort

This project in Verdun proves that a Sharp wall-mounted heat pump (Eco Inverter, R-32) can be neatly integrated into a condo balcony without sacrificing access or peace and quiet. By mechanically stabilizing the unit, controlling drainage and ensuring waterproofing , we ensure a reliable , efficient and easy-to-maintain system—ready for Quebec winters as well as the hot summers of Greater Montreal .
