This MRCOOL® DIY® 5th Generation 55,000 BTU Multi-Zone Ductless Mini-Split system pairs a single outdoor condenser with six wall-mounted air handlers (12K + 6K + 6K + 6K + 6K + 6K BTU), letting you heat and cool up to 6 separate spaces totaling as much as 2,290 sq. ft. without a full HVAC installation crew. The condenser is rated at SEER2 22 and HSPF2-4 10.6 for efficient year-round performance.
Highlights
- Pre-charged DIY® Quick-Connect® line sets use R-454B refrigerant and skip the evacuation/charging steps, simplifying installation
- Gold Fin® condensers on the wall-mount air handlers add extra corrosion resistance, a plus for coastal environments
- Control the system from the included wireless remote, the SmartHVAC app (iOS and Android), or hands-free through Amazon Alexa and Google Assistant
- Follow Me® function adjusts airflow based on the remote's location for more consistent comfort
- Included DIYPro® cable removes the need for electrical conduit during installation
- Backed by a 5-year parts warranty, a 7-year compressor warranty, and a Limited Lifetime Replacement warranty once enrolled in the MRCOOL® Care Program
