Description
This MRCOOL DIY 5th Generation ductless mini-split system pairs a 36,000 BTU 5-zone outdoor condenser with five ceiling cassette air handlers (18K BTU, 6K BTU, 6K BTU, 6K BTU, 6K BTU), giving you whole-home comfort across up to 5 separate spaces totaling around 1,500 sq. ft. from a single DIY-installed system.
Highlights
- Pre-charged DIY® Quick Connect® line sets use R-454B refrigerant, so there's no vacuuming or evacuation step during installation.
- Rated SEER2 23 / HSPF2-4 9.9 for efficient year-round heating and cooling.
- Each ceiling cassette air handler includes Follow Me® temperature tracking via the included remote for more consistent comfort in its zone.
- Control every zone from the SmartHVAC app, with full out-of-the-box support for Amazon Alexa and Google Assistant.
- Included DIYPro® cable removes the need for electrical conduit during installation.
- Low-profile cassettes fit flush between 16" ceiling joists (including pre-manufactured I-joists) for a clean, space-saving install with no visible wall unit.
Details
Avermont Direct is an authorized MRCOOL dealer, and this 5-zone DIY system is backed by a 5-year parts warranty and a 7-year compressor warranty from MRCOOL, with an optional Limited Lifetime Replacement warranty through the MRCOOL® Care Program. Because each zone is installed and controlled independently, it's well suited to comfortably heating and cooling several rooms of a home — bedrooms, a living area, and a home office, for example — from one outdoor condenser, without opening walls for ductwork.
