This MRCOOL DIY 5th Gen ductless mini-split system pairs a 55,000 BTU multi-zone condenser with six ceiling cassette air handlers (1x 18,000 BTU, 2x 12,000 BTU, 3x 9,000 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.
- Low-profile OuttaSight ceiling cassettes fit flush between 16" ceiling joists (including pre-manufactured I-joists), with no ductwork or extra wall space required.
- The Elevation function lowers the filter panel for easy cleaning, and Advanced Filtration helps maintain indoor air quality.
- 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.
