MRCOOL® DIY® 5th Gen Multi-Zone 4-Zone 27,000 BTU 23 SEER2 (6K + 6K + 6K + 9K) 4x 16ft line sets Ductless Mini-Split Air Conditioner & Heat Pump — DIYM427HPW01D00

Product Description 

Model: DIYM427HPW01D00

The MRCOOL® DIYM427HPW01D00 is a professionally balanced 4-zone ductless mini-split system engineered for homeowners who want true room-by-room comfort, high efficiency, and a legit DIY installation without sacrificing performance.

This bundle pairs the MRCOOL® DIY® 27,000 BTU 5th Generation multi-zone condenser with three 6,000 BTU air handlers and one 9,000 BTU air handler, making it ideal for homes where most rooms are smaller but one space—such as a master bedroom, office, or larger living area—needs extra capacity.

Thanks to DIY® QuickConnect® pre-charged line sets, the system arrives sealed with R-454B refrigerant, eliminating vacuuming, refrigerant handling, and HVAC licensing. Combined with DIYPRO® cable, installation is faster, cleaner, and more affordable than traditional mini-split systems.

With 23 SEER2 efficiency, DC inverter technology, and full MRCOOL® Smart HVAC Controller® support, this system delivers whisper-quiet comfort, lower energy bills, and smart control from anywhere—exactly what today’s homeowners expect.
