Copper line sets for multi-zone systems are selected by run length per zone — choose the line-set kit length you need for each zone at checkout (or supply your own). Standard factory charge covers up to 125 ft of total line length.\u003c\/p\u003e\u003ch3\u003eCan I install it myself?\u003c\/h3\u003e\u003cp\u003eMulti-zone mini splits require a licensed HVAC professional for the refrigerant connections, electrical, and startup — professional installation is also required to keep the warranty valid.

Each indoor unit has its own remote and runs independently — set a different temperature in every room, or turn off the zones you are not using to save energy.\u003c\/p\u003e\u003ch3\u003eDoes it heat as well as cool?\u003c\/h3\u003e\u003cp\u003eYes. It is an inverter heat pump — it both cools in summer and heats in winter from the same system, with rated heating down to -4°F outdoor ambient, so no separate furnace is needed in most climates.\u003c\/p\u003e\u003ch3\u003eWhat refrigerant does it use?\u003c\/h3\u003e\u003cp\u003eR454B — a next-generation lower-GWP (A2L) refrigerant. The system ships factory pre-charged; a licensed installer tops off refrigerant based on your line length.\u003c\/p\u003e\u003ch3\u003eIs everything included, or do I need to buy line sets?\u003c\/h3\u003e\u003cp\u003eThe system includes the outdoor condenser, all indoor units, and their remotes; line-set diameter adapters are packed with the outdoor unit. Copper line sets for multi-zone systems are selected by run length per zone — choose the line-set kit length you need for each zone at checkout (or supply your own). Standard factory charge covers up to 125 ft of total line length.\u003c\/p\u003e\u003ch3\u003eCan I install it myself?\u003c\/h3\u003e\u003cp\u003eMulti-zone mini splits require a licensed HVAC professional for the refrigerant connections, electrical, and startup — professional installation is also required to keep the warranty valid.

Each indoor unit has its own remote and runs independently — set a different temperature in every room, or turn off the zones you are not using to save energy.\u003c\/p\u003e\u003ch3\u003eDoes it heat as well as cool?\u003c\/h3\u003e\u003cp\u003eYes. It is an inverter heat pump — it both cools in summer and heats in winter from the same system, with rated heating down to -4°F outdoor ambient, so no separate furnace is needed in most climates.\u003c\/p\u003e\u003ch3\u003eWhat refrigerant does it use?\u003c\/h3\u003e\u003cp\u003eR454B — a next-generation lower-GWP (A2L) refrigerant. The system ships factory pre-charged; a licensed installer tops off refrigerant based on your line length.\u003c\/p\u003e\u003ch3\u003eIs everything included, or do I need to buy line sets?\u003c\/h3\u003e\u003cp\u003eThe system includes the outdoor condenser, all indoor units, and their remotes; line-set diameter adapters are packed with the outdoor unit. Copper line sets for multi-zone systems are selected by run length per zone — choose the line-set kit length you need for each zone at checkout (or supply your own). Standard factory charge covers up to 125 ft of total line length.\u003c\/p\u003e\u003ch3\u003eCan I install it myself?\u003c\/h3\u003e\u003cp\u003eMulti-zone mini splits require a licensed HVAC professional for the refrigerant connections, electrical, and startup — professional installation is also required to keep the warranty valid.
