This MRCOOL DIY 5th Gen ductless mini-split system pairs a 55,000 BTU multi-zone condenser with six wall-mount air handlers (4x 9,000 BTU, 2x 6,000 BTU), letting you heat and cool up to 6 separate spaces (up to 2290 sq. ft. combined) without hiring an HVAC professional.
Highlights
- Patented pre-charged Quick Connect line sets, filled with R-454B refrigerant, let you skip the evacuation and charging steps a traditional install requires.
- Rated 22 SEER2 and 10.6 HSPF2-4 on the condenser, so the system is built to help lower run-time energy costs.
- Control the system from the included wireless remote, the SmartHVAC app (Apple and Android), or hands-free through Amazon Alexa and Google Assistant.
- The Follow Me function on each handler's remote tracks the temperature near you and adjusts airflow to match, and Dry Mode helps manage indoor humidity.
- DIYPRO cable is included with each indoor unit, removing the need for electrical conduit during installation.
- Backed by a 5-year parts warranty, a 7-year compressor warranty, and — once enrolled in the MRCOOL Care Program — a limited lifetime replacement warranty.
