As part of our most effective residential projects this winter, the installation of a SHARP ZU1 12,000 BTU wall-mounted heat pump on the South Shore stood out for its precision, performance, and immediate impact on the customer's thermal comfort. This project, carried out by our expert team at AirGreen, perfectly illustrates how a well-chosen and well-installed HVAC system can transform a room exposed to Quebec’s climate variations into a comfortable, quiet, and energy-efficient living space—even in the heart of winter.
An ideal installation above a patio door
For this project, the wall-mounted unit was smartly installed above a sliding patio door opening onto a balcony, a common feature in urban dwellings across the South Shore. This configuration posed specific challenges: optimizing airflow circulation, avoiding obstructions, and respecting the recommended distances from windows. Thanks to the compact design of the AY-XPC12ZU1 model, our team ensured even air distribution with no direct airflow on the occupants, thanks to SHARP’s integrated Coanda airflow technology.
AirGreen expertise in action: from assessment to final results
Thermal assessment and selecting the right model
Our initial thermal evaluation of the home revealed that 12,000 BTU was sufficient to efficiently serve this well-insulated main room. The choice of the SHARP ZU1 model, known for its cold-weather performance, low noise level, and Plasmacluster air purification technology, quickly became obvious. This model is particularly appreciated for:
-
Its reliable operation down to -27°C
-
Its R32 refrigerant, environmentally responsible
-
Its Plasmacluster ion technology that purifies the indoor air
-
Its low energy consumption (SEER 21 / HSPF 12.5)
-
Its compact design, ideal for small spaces
Quick, clean, and precise installation
The wall unit was installed in a full day, including mounting the outdoor unit, precise wall coring, running refrigerant lines, and careful sealing to ensure perfect airtightness. We also integrated a secure condensate drainage system and verified airflow orientation to avoid direct air contact with room occupants.
Technical advantages of the SHARP ZU1 12,000 BTU heat pump
Technology built for Quebec’s climate
The ZU1 model stands out for its ability to deliver heat even at -27°C, thanks to SHARP’s patented Hot Gas Pipe system, which prevents the outdoor unit from freezing. This system is a major advantage in the harsh winters of the South Shore and Greater Montreal, where temperatures can plummet rapidly and for extended periods.
Plasmacluster technology: purified air, better health
Unlike conventional systems, this SHARP wall-mounted heat pump actively neutralizes viruses, bacteria, mold, and odors through its Plasmacluster technology, which emits both positive and negative ions to mimic natural air purification. The result? A healthier indoor environment, free of allergens—perfect for families with children or sensitive individuals.
Smart connectivity
This model comes Wi-Fi enabled, allowing the user to remotely control temperature settings, program operation schedules, and monitor energy consumption directly from their smartphone. It’s a feature increasingly in demand across the South Shore, especially in rental units and modern condos.
Why the South Shore particularly benefits from this type of installation
Harsh weather conditions
Cities across the South Shore of Montreal, such as Longueuil, Brossard, and Saint-Lambert, are exposed to extreme weather fluctuations. A system like the SHARP ZU1, effective in very low temperatures, ensures consistent comfort without over-reliance on central heating, while also reducing energy bills.
Long-term savings and grant eligibility
This type of installation is eligible for Hydro-Québec’s LogisVert rebates, which significantly lowers the net cost for the homeowner. At AirGreen, we assist every client in maximizing their financial return through all available government incentive programs.
Customer feedback: a noticeable difference within hours
The client, a young couple owning a condo on the South Shore, immediately noticed a clear improvement in thermal comfort and a decrease in ambient noise compared to their old electric baseboard heater. They also appreciated the visual discretion of the unit, which blended seamlessly into their interior design.
AirGreen excellence: more than just an installer
At AirGreen, we don’t just install equipment. We advise, plan, execute, and follow up post-installation. This project demonstrates our ability to deliver an optimal, aesthetic, and long-lasting result, tailored to the specific needs of every residential or commercial customer.
