Imagine transforming your space into a haven of perfect comfort with the MRCOOL DIY Mini Split 54,000 BTU 4 Zone Ceiling Cassette system — a game-changer for business owners, contractors, and HVAC professionals who demand efficiency, flexibility, and ease. This innovative 4th generation system puts you in control, delivering powerful, customizable climate management across multiple zones without the hassle of complicated installation or ductwork.

Powerful, Precise Comfort for Every Zone

Visualize your clients or customers enjoying tailored temperatures in every room — from small offices to large workshops. The system includes two 9,000 BTU and two 18,000 BTU OuttaSight Ceiling Cassette air handlers, designed to fit neatly between standard 16” ceiling joists.

Energy Efficiency That Pays Off

This system boasts an impressive 20.5 SEER2 and 8.5 HSPF-5 rating, meaning it delivers exceptional heating and cooling performance while keeping energy costs low. The Gold Fin® coated condenser resists corrosion and wear, ensuring your investment stands strong through years of use. Plus, reliable heating down to 5°F means no client gets left in the cold, no matter the season.
