DIY Easy Pro® R454B DIY 18K BTU Ductless Mini-Split Heat Pump Condenser, 230V, with 11.5 ft Install Kit

The MRCOOL® EasyPro® 18K BTU 230V Ductless Heat Pump Single Zone Mini-Split Condenser delivers powerful, energy-efficient comfort in a system designed specifically for homeowners. Built for true do-it-yourself installation, it requires no specialized tools, HVAC certifications, or prior experience, making it an excellent solution for garages, basements, attics, bonus rooms, and other spaces up to 800 square feet.

While installation is simple, performance is anything but basic. With a 20 SEER2 cooling efficiency and an 8.5 HSPF2-4 heating rating, the EasyPro® 18K provides steady, reliable comfort throughout the year while using less energy than traditional systems.

Setup is made even easier with the included 11.5-foot Quick Connect® line set, which arrives factory pre-charged with environmentally friendly R-454B refrigerant. This eliminates vacuum pumps, refrigerant handling, and specialized HVAC tools, reducing installation time and minimizing common setup errors.

Once installed, control is effortless. The included wireless remote and the MRCOOL® Comfort app allow you to adjust temperatures, create schedules, and monitor energy usage from virtually anywhere. Amazon Alexa and Google Assistant compatibility adds hands-free voice control for added convenience.

Comfort-enhancing features such as Dry Mode, Sleep Mode, Auto Mode, and programmable scheduling automatically balance comfort and efficiency, while the Gold Fin® condenser coating provides superior corrosion resistance for humid or coastal environments.

For added peace of mind, the EasyPro® 18K is backed by a 5-year compressor warranty and a 3-year parts warranty, reflecting MRCOOL®’s confidence in the durability and quality of every system.
