DIY Easy Pro® R454B DIY 9K BTU Ductless Mini-Split Heat Pump Condenser, 115V, with 11.5 ft Install Kit

The MRCOOL® EasyPro® 9K BTU 115V Ductless Heat Pump Single Zone Mini-Split Condenser is designed to make high-efficiency home comfort simple and accessible. Built for true do-it-yourself installation, it requires no specialized HVAC tools or professional experience, making it ideal for garages, home offices, studios, workshops, and other spaces up to 400 square feet.

Despite its DIY-friendly design, the EasyPro® 9K delivers impressive performance with a 20.2 SEER2 cooling rating and 9.2 HSPF2-4 heating efficiency. This allows the system to maintain consistent indoor comfort throughout the year while using less energy, helping reduce utility costs and provide long-term savings.

Installation is streamlined with an 11.5-foot Quick Connect® line set that arrives factory pre-charged with environmentally friendly R-454B refrigerant, eliminating the need for vacuum pumps or refrigerant handling. This makes setup faster, cleaner, and more approachable for first-time installers.

Everyday control is simple and flexible using the included wireless remote or the MRCOOL® Comfort app, which allows temperature adjustments, scheduling, and energy monitoring from anywhere. Compatibility with Amazon Alexa and Google Assistant adds hands-free convenience.

Features like Dry Mode, Sleep Mode, Auto Mode, and programmable scheduling automatically optimize comfort and efficiency, while a Gold Fin® condenser coating provides added corrosion resistance for humid or coastal environments.

For peace of mind, the EasyPro® 9K includes a 5-year compressor warranty and a 3-year parts warranty, reflecting MRCOOL®’s confidence in the quality and reliability of every system.
