MrCool DIY 24k BTU Single-Zone Mini-Split System

For homeowners who require a powerful heating and cooling solution for a single large space—such as a great room, workshop, or garage—the Mr. Cool 4th Generation DIY 24k BTU Mini-Split offers an unbeatable combination of efficiency, simplicity, and performance. This ENERGY STAR-certified all-in-one system is specifically designed for homeowner installation, saving you hundreds or even thousands on installation costs.

The Do-It-Yourself Advantage

The core feature of the MrCool DIY line is its revolutionary installation process. This system includes the patented MrCool Pre-Charged Quick-Connect Line Set. These lines are pre-filled with the correct amount of R-410A refrigerant and can be connected between the indoor and outdoor units using just basic hand tools. This eliminates the need for specialized vacuuming equipment, charging devices, or a certified technician for the most complex part of the job, allowing for a complete installation in just a few hours.

High-Efficiency, Variable-Speed Performance

This system is built around a variable-speed DC inverter compressor, the key to its incredible efficiency. By constantly adjusting its operational speed to match the room's needs precisely, the compressor avoids the energy-wasting on/off cycles of older technology. This allows the unit to achieve a stellar 20.5 SEER2 rating and earn its ENERGY STAR® certification, translating directly into lower energy bills for you. It’s also a powerful heat pump, capable of providing warmth even when outdoor temperatures plummet to -13°F.

Smart Features for Personalized Comfort

The MrCool DIY Mini Split is packed with modern technology. It features built-in Wi-Fi, enabling you to control the unit remotely from anywhere using the Smart HVAC app on your smartphone. A standout feature is the Follow Me™ function; when activated, the system reads the temperature at the handheld remote's location, not just at the wall unit. This ensures the temperature you feel is the temperature you want. With multiple operating modes like COOL, HEAT, DRY (dehumidify), and SLEEP, you can tailor your comfort perfectly.
