In a quiet residential neighborhood in Lachine, our team of HVAC installation experts recently completed a tailored project: the installation of a SHARP ZU1 18000 BTU wall-mounted heat pump. This high-performance system, known for its reliability and advanced technology, was carefully chosen to meet the heating and cooling needs of a single-family home while respecting the aesthetic and structural constraints of the property.
Why this Lachine residence needed a high-performance solution
Located in an area with frequent temperature fluctuations, the home had a clear need for a system capable of efficient heating even at -27°C, while also providing optimal cooling in summer. The client, concerned about energy consumption and indoor air quality, was looking for a reliable, quiet, and long-lasting solution.
After a complete assessment of the space and expectations, the SHARP ZU1 18000 BTU wall-mounted heat pump stood out as the ideal choice.
A technical overview of the SHARP ZU1 18000 BTU heat pump
SHARP’s ZU1 series represents the pinnacle of cutting-edge Japanese HVAC technology for residential applications. Here are the key features of this unit:
-
Heating capacity: Up to 21,800 BTU/h, maintaining consistent performance down to -27°C thanks to SHARP’s exclusive HOT GAS PIPE system.
-
Cooling capacity: 18,000 BTU/h, ideal for a large open area or multiple connected zones.
-
Refrigerant: R32, an environmentally friendly refrigerant with a Global Warming Potential (GWP) one-third lower than R410A.
-
Plasmacluster Technology: unique to SHARP, it purifies the air by neutralizing viruses, bacteria, allergens, and odors without any chemicals.
-
SEER: 24 / HSPF: 10 – An energy efficiency rating that exceeds industry standards.
Technical challenges on site: spatial constraints and aesthetic finish
The installation took place in a room corner with decorative ceiling moldings. We had to precisely adapt the positioning of the indoor unit to ensure optimal air circulation while preserving the visual harmony of the space. Thanks to our expertise in wall-mounted heat pump installations in Lachine, we successfully:
-
Securely mounted the unit at a height allowing even air distribution throughout the room.
-
Used a discreet wall pass-through for refrigerant lines, minimizing visible outdoor piping.
-
Ensured effective and invisible drainage, even in winter, with a perfectly sloped connection to the existing storm drain system.
