MrCool DIY 18k BTU 22 SEER Single-Zone Mini-Split

If you're looking for a highly efficient way to heat and cool a single large room or area—like a master bedroom, living room, or garage—the MrCool DIY 18k BTU Single-Zone Mini-Split is a fantastic, cost-effective solution. This ENERGY STAR-certified system is specifically designed for do-it-yourself installation, allowing you to achieve high-performance comfort without the high cost of a professional installer.

The Do-It-Yourself Advantage

The primary feature that distinguishes this MrCool diy mini split is its revolutionary DIY installation. The system comes with a pre-charged 25-foot line set that uses patented Quick-Connect fittings. This means the lines are already filled with the proper amount of R-410A refrigerant and can be connected by a homeowner using just basic hand tools. This process eliminates the need for expensive, specialized HVAC tools, such as vacuum pumps and gauges, saving you time and money.

High-Efficiency Performance

The 18,000 MrCool Mini Split BTU system is powerful enough to handle spaces up to 750 sq. ft. and does so with incredible efficiency. It boasts a 22 SEER rating (22.7 SEER2), earning it an ENERGY STAR® certification for its energy-saving performance. The core of this efficiency is its variable-speed DC inverter compressor, which precisely adjusts its speed rather than just turning on and off. This not only cuts operating costs but also provides more consistent temperatures and better humidity control.

Smart and Durable Features

This 4th-generation MrCool system is packed with modern technology. It comes with built-in Wi-Fi, allowing you to control your system from anywhere using the Smart HVAC app on your phone. It also includes a remote with the Follow Me™ function, which measures the temperature at the remote's location, not just at the wall unit, ensuring your comfort. The outdoor unit is built to last with a Gold Fin® condenser that provides corrosion resistance, making it a durable choice for coastal areas.
