Tackling an HVAC installation yourself may seem daunting, but the 5th Generation MRCOOL® DIY® 18k BTU 22.5 SEER Ductless Heat Pump Single Zone Mini Split System is built to make the process straightforward and hassle-free. This unit is perfect for heating or cooling spaces ranging from 500 to 700 square feet, and is designed specifically for homeowners—no special tools or prior experience needed. The system comes with a 25-foot Quick Connect® line set, pre-charged with R-454B refrigerant, which means there’s no need to vacuum the lines. This makes the installation process faster, safer, and more affordable. You’ll enjoy flexible control options, including a handheld remote, the SmartHVAC app for iOS and Android, and compatibility with voice control through Amazon Alexa and Google Assistant. The Follow Me® feature helps maintain your ideal comfort by adjusting the temperature based on where the remote is located. Additionally, the corrosion-resistant Gold Fin® condenser coating is ideal for coastal environments, offering extra durability and extended performance. With user-friendly features like Auto mode, programmable timers, and automatic restart after power outages, the system is engineered for efficiency and convenience. The unit is backed by MRCOOL’s industry-leading support: a base warranty that includes 7-year compressor and 5-year parts coverage and eligibility for the MRCOOL® Care Program.
