MRCOOL DIY® 5th Gen Multi-Zone 6-Zone 55,000 BTU 22 SEER2 (6K + 9K + 24K) & three 16ft line sets Ductless Mini-Split Air Conditioner & Heat Pump — DIYM355HPW01D00
Product Description
Model: DIYM355HPW01D00
The MRCOOL DIY® 5th Generation 55,000 BTU 6-Zone Multi-Zone Mini-Split System is designed for homeowners who want whole-home comfort, professional-level efficiency, and a true DIY installation—without paying contractor labor.
This complete system pairs the powerful MRCOOL® DIY-MULTI6-55HP230D-O condenser with a carefully matched combination of 6K, 9K, and 24K indoor air handlers, making it ideal for homes with mixed room sizes such as bedrooms, offices, living areas, and open-concept spaces.
Thanks to MRCOOL’s patented DIY® QuickConnect® line sets, this system arrives factory-charged with R-454B refrigerant, eliminating vacuum pumps, gauges, or EPA licensing. The included DIYPRO® cable removes the need for conduit, speeding up installation while improving durability.
Each zone operates independently, allowing you to fine-tune comfort room-by-room while reducing wasted energy—something traditional central HVAC systems simply can’t match.
