This MRCOOL DIY 5th Generation 2-zone ductless mini-split system pairs an 18,000 BTU outdoor condenser with a 12,000 BTU ceiling cassette air handler and a 6,000 BTU ceiling cassette air handler, so you can heat and cool two separate rooms without hiring an HVAC professional. The condenser is rated 23.9 SEER2 and 10 HSPF2-4 for efficient year-round performance.
