Frequently Asked Questions

How does a multizone heat pump system work?

+

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.

How many indoor units can I connect to one outdoor unit?

+

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.

What's the difference between the pipe length options?

+

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.

What is the QuickConnect system and why should I choose it?

+

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.

Can I control different temperatures in different rooms?

+

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.

How energy efficient is the Boreas Series?

+

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.

Do I need one pipe length per indoor unit?

+

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.
