MRCOOL DIY Mini Split - 36,000 BTU 3 Zone Ceiling Cassette Ductless Air Conditioner and Heat Pump with 25 ft. Install Kit (DIYM336HPC05C28)

Transform your HVAC business offerings with MRCOOL's revolutionary 4th Generation DIY Mini Split system – the competitive edge that delivers higher profits, faster installations, and exceptional customer satisfaction. This premium 3-zone package equips you to provide sophisticated climate solutions that outperform traditional systems while slashing installation time and complexity.

Picture this: Your clients walk into their newly finished spaces, searching for the source of the perfect comfort they're feeling. The sleek ceiling cassettes blend so seamlessly into the ceiling that they barely notice them – just pristine, customized comfort flowing invisibly from above. No unsightly wall units interrupting their design aesthetic, no bulky ductwork stealing precious ceiling height – just the invisible luxury of perfect temperature control that makes their space feel truly complete.

At the heart of this system is the powerful 36,000 BTU condenser engineered with industry-leading 21.5 SEER2 and 8.5 HSPF-5 ratings – efficiency numbers that translate directly to substantial energy savings your clients will see month after month. The robust Gold Fin® coating provides superior protection against coastal elements and environmental corrosion, ensuring long-lasting performance that enhances your installation's reputation. Even in the harshest winter conditions, this system continues delivering reliable heat down to an impressive -13°F, providing true all-season comfort few competitors can match.

The included 12,000 BTU ceiling cassette air handler installs discreetly between standard 16" joists, creating a modern, low-profile solution that disappears into the ceiling while efficiently controlling temperatures in spaces up to 500 square feet. Multiple operating modes including cooling, heating, auto, dry, and sleep functions give your clients complete control over their environment in every season.

What truly sets MRCOOL apart is the revolutionary pre-charged Quick Connect Line Sets. These 25-foot copper lines come pre-filled with R-410A refrigerant, eliminating the need for vacuum pumps, specialized equipment, or certified technicians. This game-changing technology means your installation teams can complete jobs in a fraction of the time, dramatically reducing labor costs while maintaining premium quality. No specialized certifications required – just increased productivity and higher profit margins for your business.
