This MRCOOL® DIY® 5th Generation 27,000 BTU ductless mini-split system pairs a 3-zone condenser with 18,000 + 6,000 + 6,000 BTU indoor air handlers (18,000 BTU Ceiling Cassette (OuttaSight®), 6,000 BTU Ceiling Cassette (OuttaSight®), 6,000 BTU Ceiling Cassette (OuttaSight®)), and installs without an HVAC professional. The condenser is rated up to 4 zones and up to 1,000–1,200 sq. ft. of combined coverage, with a SEER2 of 23 and an HSPF2-4 of 9.5.

- Included DIYPro® cable eliminates the need for electrical conduit between the condenser and each indoor unit.
- SmartHVAC app (Apple and Android) plus Amazon Alexa and Google Assistant/Google Home compatibility let you set schedules, switch modes, and monitor the system remotely.
- Follow Me® function on each included remote adjusts airflow based on the remote's location for more even comfort.
- Gold Fin® condenser coil offers added corrosion resistance, a benefit in coastal or high-humidity climates.
- Backed by a 5-year parts warranty and a 7-year compressor warranty, with a Limited Lifetime Replacement warranty available through enrollment in the MRCOOL® Care Program.
