CYK018GMSI24RL — Pioneer Quantum Ultra 18,000 BTU 22 SEER2 230V Single-Way Ceiling Recessed Cassette Ductless Mini-Split Air Conditioner Inverter Heat Pump with 10 ft Line Set

CYK018GMSI24RL — Pioneer Quantum Ultra 18,000 BTU 22 SEER2 230V Single-Way Ceiling Recessed Cassette Ductless Mini-Split Air Conditioner Inverter Heat Pump

The Pioneer Quantum Ultra 18,000 BTU one-way ceiling recessed cassette mini-split (manufacturer part CYK018GMSI24RL) 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 (YN018GMSI24RPG) pairs with one indoor unit (—) — this is a single-zone system, not a multi-zone. It ships nationwide, and our team can confirm sizing before you order.

At 22.2 SEER2 and roughly 1.5 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 corridors, small offices, and narrow rooms where a full 4-way cassette will not fit the ceiling grid.
