MRCOOL DIY 5th Gen Multi-Zone 3-Zone 36,000 BTU 23 SEER2 (9K Wall Mount + 12K Wall Mount + 18K Ceiling Cassette) Ductless Mini-Split Air Conditioner and Heat Pump
Heat and cool 3 rooms with this mixed MRCOOL DIY 5th Gen multi-zone system. This bundle pairs 2 wall mounted air handlers and 1 ceiling cassette air handler with a 36,000 BTU multi-zone condenser, giving customers the flexibility to use discreet ceiling cassette comfort in open living areas while keeping familiar wall mounted air handlers in bedrooms, offices, or secondary rooms.
The MRCOOL DIY system is designed for easier installation with compatible pre-charged Quick Connect line sets, R-454B refrigerant, app-based controls, and year-round heat pump performance. Ceiling cassettes install out of the way between standard joists, while wall mounted air handlers offer a straightforward, efficient solution for rooms where wall placement is preferred. Line sets are selected separately from the product options.
