Discreet and High-Performance Integration Above a Window: A Custom HVAC Project in Lorraine
At AirGreen, every HVAC installation represents an opportunity to demonstrate our technical rigor and our ability to adapt the best solutions to the specific realities of each residence. This project carried out in Lorraine, on Montreal's North Shore, perfectly illustrates this approach: a FUJITSU KZ 12,000 BTU wall-mounted heat pump, installed above a window in a confined space, requiring precision, expertise, and attention to detail.
A Demanding Residential Context: Space Constraints and Comfort Optimization
The client contacted us with the goal of improving the thermal comfort of their main living space, particularly during hot summer periods and the harsh cold typical of Quebec's climate. The ideal location for the indoor unit was limited: a wall above a window, framed by solid wood moldings.
Identified Challenges:
- Restricted space between the ceiling and the top of the window
- Presence of decorative moldings to be preserved
- Need for optimal positioning for uniform air distribution
- Significant aesthetic constraints for the client
Heat Pump Choice: FUJITSU KZ 12,000 BTU
We recommended a FUJITSU KZ 12,000 BTU heat pump, a model renowned for its reliability, energy efficiency, and cold climate performance.
Key Technical Characteristics:
- Capacity: 12,000 BTU
- Refrigerant: R-32, more eco-friendly and efficient
- SEER2: up to 26+
- HSPF2: approximately 12.5
- Efficient operation down to -25°C
- Indoor sound level: extremely quiet
- Integrated Wi-Fi for remote control
Why this choice was optimal:
- Perfect for a medium-sized room
- Excellent energy efficiency eligible for subsidy programs
- Compact format ideal for installation above a window
Mastered Technical Installation in a Delicate Space
Installation above a window requires special attention, both structurally and aesthetically. Our technicians proceeded methodically to ensure perfect integration.
Key Installation Steps:
1. Preparation and precise measurement
We took exact measurements of the available dimensions to position the indoor unit centrally and balanced.
2. Adjustment of wall mounts
Given the presence of moldings, we used adapted supports to ensure a solid fixation without damaging the existing structure.
3. Strategic drilling for conduit passage
The wall hole was precisely made to allow the passage of refrigerant lines, drain, and electrical wiring, while minimizing visual impact.
4. Vacuum pull and micron test
As always at AirGreen, we performed a complete vacuum pull to eliminate any moisture in the system. The micron test confirmed perfect sealing.
5. Outdoor unit installation
The outdoor unit was installed on a stable support, with sufficient clearance to ensure optimal performance in winter.
Final Result: Aesthetics, Performance, and Customer Satisfaction
The result is a clean, discreet, and perfectly integrated installation. The indoor unit fits harmoniously above the window, without compromising the room's aesthetics.
Immediate Benefits for the Customer:
- Constant thermal comfort in summer and winter
- Significant reduction in energy costs
- Smart control via Wi-Fi
- Remarkable operating silence
Available Subsidies and Return on Investment
Thanks to its energy efficiency, the FUJITSU KZ heat pump is eligible for Hydro-Québec's LogisVert program.
Estimated Financial Details:
- Potential subsidy: approximately $1,200 to $1,500
- Annual savings on energy bills
- Rapid amortization of the investment
