A garage, basement, workshop, or bonus room can need dependable heating and cooling without making installation unnecessarily complicated. The EZPRO-18-HP-WMAH-230DE-O is an 18,000 BTU ductless mini-split heat pump air handler designed for spaces up to 800 sq ft, providing year-round heating and cooling in the MRCOOL DIY EasyPro series.
The system combines efficiency and air-quality features for everyday operation. Active Clean Technology and reusable filters support cleaner air, while R-454B refrigerant provides the specified refrigerant configuration. Low-ambient cooling down to 5°F also allows the unit to provide cooling in lower outdoor temperatures, supporting specialized applications such as server rooms or greenhouses where consistent climate control is required.
Installation is supported by MRCOOL Quick Connect® line sets, which are factory pre-charged with R-454B refrigerant. The included 13-foot DIYPRO® cable replaces traditional electrical conduit, while the Gold Fin® condenser coating provides corrosion resistance for humid or coastal environments.
Control is designed to be straightforward. Integrated WiFi and the MRCOOL Smart HVAC Controller allow operation through connected controls, with Amazon Alexa and Google Assistant providing hands-free voice operation. A wireless remote, Dry Mode, Sleep Mode, and Auto Mode provide additional operating options.
