This MRCOOL® DIY® 5th Generation Multi-Zone Ductless Mini-Split system pairs a 55,000 BTU outdoor condenser with six wall-mounted indoor air handlers (18K + 9K + 9K + 9K + 6K + 6K BTU), giving you DIY-installable heating and cooling across up to 6 separate spaces totaling as much as 2,290 sq. ft. from a single MRCOOL® condenser.
Highlights
-
No HVAC professional required – the patented pre-charged Quick-Connect® line sets use R-454B refrigerant and skip the evacuation and charging steps of a traditional install.
-
Efficient performance – the condenser is rated SEER2 22 and HSPF2-4 10.6.
-
Smart control – operate the system with the Smart HVAC app (Apple and Android) or hands-free through Amazon Alexa and Google Assistant, in addition to the included wireless remote.
-
Six-zone flexibility – this condenser powers a 18K + 9K + 9K + 9K + 6K + 6K BTU wall mount air handler combination, so each space can be heated or cooled independently.
-
DIYPro® cable included – removes the need for electrical conduit and adds protection against outdoor elements and wildlife.
-
Follow Me® and Gold Fin® Condenser – the remote's Follow Me® function adjusts airflow based on its location, and the Gold Fin® Condenser resists corrosion, which is useful in coastal environments.
-
Backed by a strong warranty – 5-year parts warranty, 7-year compressor warranty, and a Limited Lifetime Replacement warranty once enrolled in the MRCOOL® Care Program.
