Consistent performance, a significant reduction in energy costs, and customized thermal comfort: that’s what this downtown Montréal business achieved after installing a multi-zone heat pump with AirGreen. Completed over ten years ago, this project still stands today as a clear example of the long-term value of well-designed multi-zone HVAC solutions. Through this real-life testimonial, we dive into the world of commercial energy efficiency, highlighting the technical decisions, on-site challenges, and tangible benefits that followed.
A Complex Need: Heating and Cooling Multiple Independent Zones
The establishment in question is a two-story retail business that includes a storefront, office space, storage for merchandise, and a break area for staff. Each of these zones had different thermal requirements, varying according to foot traffic, electronic equipment use, or the nature of the goods stored. The old central system, energy-hungry and inflexible, no longer met modern comfort standards or the economic expectations of the business owner.
A Strategic Solution: The Multi-Zone Heat Pump
At AirGreen, we quickly steered this client toward a multi-zone wall-mounted heat pump, capable of independently supplying up to five indoor units. This approach came with numerous benefits:
-
Individual zone control: each room is managed with its own thermostat.
-
Increased energy efficiency: units run only when needed.
-
Discreet design and flexible installation: the wall units easily integrate with various decors without requiring major renovations.
-
Eligibility for local grants thanks to excellent SEER/HSPF ratings.
The selected model at the time was a Fujitsu multi-zone heat pump (model AOU45RLXFZ) with four ASU12RLF wall-mounted units. This 45,000 BTU system provided enough power to meet the entire business’s needs while ensuring ENERGY STAR-level energy efficiency, with a SEER of 18 and HSPF of 10.
Installation Process: Clean, Fast, and Strategically Executed
We scheduled the installation over two full days, outside of business hours, to avoid disrupting commercial activities. Our technicians carefully mapped out the refrigerant lines, securely mounted the outdoor unit on a vibration-absorbing wall bracket, and connected the electrical conduits with minimal visibility.
Technical Challenges Faced:
-
Limited access to certain areas: especially the basement storage, which required a specific wall opening.
-
Soundproofing requirements: we used insulated ducts and anti-vibration mounts.
-
Coordination with the IT team: some units were installed near sensitive computer equipment, requiring carefully calibrated airflow.
Our team was able to adapt the installation to each constraint, strictly adhering to safety, aesthetic, and energy performance standards.
10-Year Results: Savings, Reliability, and Lasting Comfort
A decade later, the business owner reports a clearly positive return on investment. Here are the tangible results observed:
-
A 37% reduction in annual energy bills compared to the previous system.
-
No major breakdowns thanks to regular annual maintenance by AirGreen.
-
Improved staff and customer satisfaction due to stable year-round thermal comfort.
-
No replacement needed: the wall units and the outdoor compressor are still operating optimally.
This real-life example perfectly illustrates the longevity and profitability of a well-chosen and well-installed multi-zone heat pump.
HVAC Maintenance: The Key to Longevity
The success of this installation also stems from a strict preventive maintenance strategy, carried out by our team. Each year, we perform:
-
A full cleaning of the filters and coils.
-
A check of refrigerant pressure.
-
A performance test of each indoor unit.
-
A high-pressure cleaning of the outdoor unit.
This discipline ensures consistent performance and maximizes the system’s lifespan, while maintaining the validity of the manufacturer’s warranty.
