CYB048GMSI20RL — Pioneer Quantum Ultra 48,000 BTU 19 SEER2 230V 4-Way Ceiling Cassette Ductless Mini-Split Air Conditioner Inverter Heat Pump with 10 ft Line Set

CYB048GMSI20RL — Pioneer Quantum Ultra 48,000 BTU 19 SEER2 230V 4-Way Ceiling Cassette Ductless Mini-Split Air Conditioner Inverter Heat Pump

The Pioneer Quantum Ultra 48,000 BTU 4-way ceiling cassette mini-split (manufacturer part CYB048GMSI20RL) is a complete, factory-matched single-zone heat pump system with the 10 ft copper line set included sold by Cedars HVAC. One outdoor condenser (YN048GMSI20RUG) pairs with one indoor unit (CB048GMSILDFHG) — this is a single-zone system, not a multi-zone. It ships nationwide, and our team can confirm sizing before you order.

At 19.0 SEER2 and roughly 4 ton of capacity, this unit both cools and heats, so it replaces a separate air conditioner and furnace in the zone it serves. It is a strong fit for open commercial floor plates with a suspended ceiling, giving even 360° throw from the center of the room.
