Description
This MRCOOL DIY 5th Generation 6-Zone Mini Split pairs a 48,000 BTU ductless outdoor condenser with six wall-mounted indoor air handlers (18K + 12K + 12K + 9K + 6K + 6K BTU), letting you heat and cool up to 6 separate spaces, up to 2,000 sq. ft. combined, without hiring an HVAC professional.
Highlights
- Pre-charged DIY® Quick Connect® line sets filled with R-454B refrigerant let you skip the vacuuming and charging steps that a traditional mini-split install requires.
- Rated 21.8 SEER2 and 10 HSPF2-4, so the system is built to run efficiently across both cooling and heating seasons.
- Six wall-mounted air handlers (18K + 12K + 12K + 9K + 6K + 6K BTU) give you independent, zone-by-zone temperature control in up to 6 rooms.
- Included DIYPro® cable removes the need for electrical conduit, and the Gold Fin® condenser coil resists corrosion in coastal climates.
- Control the system by wireless remote, the SmartHVAC app (iOS/Android), or hands-free through Amazon Alexa and Google Assistant, with Follow Me and Dry Mode built in.
- Backed by a 5-year parts warranty, a 7-year compressor warranty, and a Limited Lifetime Replacement warranty when enrolled in the MRCOOL® Care Program.
