The Boreas Series Multizone heat pump system represents the pinnacle of climate control technology, designed specifically for homes and spaces requiring customized temperature management across multiple rooms. With a single outdoor unit powering up to five indoor units, the Boreas Series delivers exceptional energy efficiency while providing personalized comfort in every zone of your home.
Engineered to withstand North American climate extremes, the Boreas Series maintains optimal performance in temperatures as low as -13°F (-25°C), ensuring year-round comfort regardless of outdoor conditions. The system's advanced inverter technology, whisper-quiet operation, and integrated Wi-Fi control make it the perfect solution for modern living spaces where comfort, efficiency, and convenience are paramount.
The Boreas Series utilizes advanced multizone technology that allows a single outdoor unit to connect to multiple indoor units, each operating independently to maintain different temperatures in different rooms. This innovative approach offers several key advantages:
The Boreas Series combines cutting-edge technology with thoughtful design to deliver an unparalleled climate control experience.
The Boreas Series features a state-of-the-art DC inverter compressor that continuously adjusts its speed to maintain precise temperature control while minimizing energy consumption. This advanced technology eliminates the inefficient on-off cycling of conventional systems, resulting in up to 40% energy savings, smoother operation, and extended system lifespan.
The Boreas Series utilizes precision electronic expansion valve (EEV) technology that dynamically adjusts refrigerant flow based on real-time demand. This intelligent system ensures optimal performance across all connected zones while maximizing energy efficiency and maintaining stable, comfortable temperatures throughout your home.
Engineered for peaceful living environments, the Boreas Series features advanced sound-dampening technology and precision-balanced DC fan motors. Indoor units operate at noise levels as low as 22dB(A) – quieter than a whispered conversation – while the outdoor unit's specially designed acoustic enclosure minimizes sound transmission to neighboring properties.
The Boreas Series outdoor unit features premium Gold Fin coil protection technology that shields heat exchanger surfaces from environmental corrosion, salt exposure, and acid rain. Tested to withstand 1500 hours in salt spray conditions, this specialized coating significantly extends system lifespan even in harsh coastal environments.
The Boreas Series' advanced zone control system allows each indoor unit to operate independently, creating personalized comfort zones throughout your home. This intelligent technology optimizes energy usage by directing heating or cooling only where needed, while the system's load-balancing capabilities ensure consistent performance even during peak demand periods.
Control your entire Boreas Series system from anywhere using the intuitive smartphone app. Adjust individual zone temperatures, set custom schedules, monitor energy usage, and receive maintenance alerts – all from your mobile device. The system also integrates seamlessly with popular smart home platforms for voice control and automated comfort.
Take advantage of federal, provincial, and utility rebates to make your investment in the Boreas Series even more affordable.

A multizone heat pump system consists of a single outdoor unit connected to multiple indoor units. The outdoor unit contains the compressor and main heat exchange components, while each indoor unit delivers conditioned air to a specific zone or room. Refrigerant lines connect the outdoor unit to each indoor unit, allowing for independent temperature control in each zone while using just one outdoor system.
The number of indoor units depends on the capacity of your outdoor unit. The Boreas 24,000 BTU model supports up to 3 indoor units, the 36,000 BTU model supports up to 4 indoor units, and the 48,000 BTU model supports up to 5 indoor units. Each configuration has specific compatibility requirements to ensure optimal performance.
The pipe length determines how far each indoor unit can be installed from the outdoor unit. The 16ft option is ideal for indoor units installed on the same wall or nearby the outdoor unit. The 25ft option works well for units installed on adjacent walls or in nearby rooms. The 50ft option is designed for installations where the indoor unit is far from the outdoor unit, such as on opposite sides of the home or on different floors.
The QuickConnect system is an innovative tool-free connection system that simplifies installation and reduces the risk of refrigerant leaks. Traditional connections require specialized tools and precise torquing of flare connections. QuickConnect uses pre-charged line sets with quick-connect fittings that simply snap together, reducing installation time by up to 50% and virtually eliminating the risk of improper connections that could lead to refrigerant leaks.
Yes, that's one of the main benefits of a multizone system. Each indoor unit has its own temperature control, allowing you to set different temperatures in different zones. For example, you could keep bedrooms cooler while maintaining a warmer temperature in living areas. Each zone can be controlled independently via the included remote controls or through the smartphone app.
The Boreas Series features a high-efficiency rating with SEER values up to 22 and HSPF values up to 11.5, exceeding ENERGY STAR® requirements. This translates to approximately 40% energy savings compared to conventional HVAC systems. The DC inverter technology continuously adjusts output to maintain precise temperatures without the energy waste of traditional on/off cycling.
Yes, each indoor unit requires its own refrigerant line set (pipe) to connect to the outdoor unit. You'll need to select one pipe length for each indoor unit in your configuration. The lengths can be different for each indoor unit depending on their installation locations relative to the outdoor unit.
