MRCOOL DIY Mini Split - 42,000 BTU 2 Zone Ductless Air Conditioner and Heat Pump, DIY-B-248HP1824
Unlock superior comfort and effortless installation with the MRCOOL DIY Mini Split 42,000 BTU 2 Zone system — designed for business owners, contractors, and HVAC professionals who want to deliver top-tier climate control with unmatched ease. This 4th Generation system is engineered to provide powerful, energy-efficient heating and cooling across multiple rooms, all while eliminating the need for specialized tools or technicians.
Imagine completing complex multi-zone HVAC installs without the usual headaches. Thanks to MRCOOL’s patented Pre-Charged Quick Connect Line Sets, you can install the condenser and air handlers quickly and confidently—no vacuum pumps, no refrigerant charging, no specialized equipment required. This streamlined process saves you time and labor costs, allowing you to take on more projects and increase your profitability.
The system includes a 42,000 BTU condenser paired with two versatile air handlers: an 18,000 BTU unit optimized for rooms between 501 and 750 square feet, and a 24,000 BTU handler designed for larger spaces from 751 to 1,000 square feet. Both air handlers offer multiple operating modes — COOL, HEAT, AUTO, DRY, and SLEEP — giving your customers complete control over their comfort throughout the year.
Built to last, the condenser features a Gold Fin® coating that protects against corrosion and wear, making it ideal for installations in coastal or harsh environments. This robust protection means fewer callbacks and greater customer satisfaction over the long term.
With SmartHVAC app compatibility, the MRCOOL DIY Mini Split lets your customers manage their system remotely from anywhere. Whether they want to adjust temperatures before arriving home or monitor system performance on the go, this smart feature adds convenience and modern appeal to your installations.
