Precise installations, surprising results: our experience with Sharp wall-mounted heat pumps
At AirGreen, we’ve installed a wide variety of wall-mounted heat pumps throughout the Greater Montréal Area, from Laval to Longueuil, including the North Shore and South Shore. One brand that rarely draws attention but consistently impresses after installation is Sharp. Not widely known in the HVAC world in Québec, this Japanese brand offers precise engineering, consistent performance, and an unbeatable price-to-performance ratio.
Why are more and more customers choosing Sharp wall-mounted heat pumps?
Unlike more well-known brands like Gree or Fujitsu, Sharp doesn’t focus on marketing. Instead, it delivers reliability, energy performance, and quiet comfort. Customers often choose Sharp only after a technical recommendation or detailed comparison. But once the unit is installed, the feedback is unanimous: “Why isn’t this brand more popular?”
Focus on the Sharp ZU1 models: durability and efficiency
One of the most frequently installed models is the Sharp ZU1, available in 15,000, 18,000, and 24,000 BTU. It stands out thanks to:
-
Very low sound levels (as low as 21 dB at low indoor fan speed)
-
Outstanding energy efficiency, with SEER ratings above 20
-
Heating capacity down to -25°C, ideal for Québec winters
-
A sleek and discreet design, fitting any interior style
Real-life example: Installation in Oka – Sharp ZU1 15,000 BTU
We recently completed an installation in a single-family home in Oka, on the North Shore. The customer was looking for an affordable yet high-performing alternative to their old portable air conditioner. After careful analysis, we recommended a 15,000 BTU Sharp ZU1, eligible for a $2,172 LogisVert grant from Hydro-Québec.
Challenges faced:
-
The exterior wall didn’t allow for a direct exit to the desired unit location
-
The electrical panel was far away, requiring discreet cable routing
Solutions provided:
-
Compressor installed on a raised concrete base with anti-vibration insulation
-
Precise core drilling with protective sleeve, ensuring airtightness and a clean interior finish
-
Dedicated line pulled over 20 metres, with exterior conduit hidden along the roof edges
The result? Stable heating even at -22°C, a satisfied client, and a year-round comfortable living space.
An underrated but cost-effective alternative
We also recently installed a 24,000 BTU Sharp ZU1 in a duplex in Pierrefonds and an 18,000 BTU unit in a house in Laval. In both cases, the key deciding factor was value: performance close to premium brands, but at 15 to 20% lower cost, including grants. This makes it possible for many of our clients to maximize their return on investment while benefiting from a durable system.
What our clients appreciate most:
-
Silent operation: especially valued in bedrooms or home offices
-
Even temperature distribution: thanks to automatic horizontal and vertical airflow
-
Intuitive remote control with backlit screen and customizable modes

Practical tips before installing a Sharp heat pump
Choose the right capacity:
-
15,000 BTU: perfect for medium to large rooms, up to 900 sq. ft.
-
18,000 BTU: ideal for open-concept spaces or entire floors
-
24,000 BTU: for large homes, lofts, or duplexes
Evaluate insulation:
Proper insulation helps optimize system efficiency and avoids oversizing the unit.
Consider window orientation:
South-facing exposure increases solar gain. We then adjust the configuration and operation settings to prevent overheating or excess energy use.
Interesting grants for Sharp models
Sharp heat pumps qualify for the Hydro-Québec LogisVert financial assistance program and other regional grants. The amounts range from $1,704 to over $2,172, depending on the model and climate zone.
Conclusion: A brand worth serious consideration
