Description
This MRCOOL DIY 5th Generation 2-zone ductless mini-split system pairs an 18,000 BTU outdoor condenser with two identical 12,000 BTU ceiling cassette air handlers, 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.
Highlights
- DIY installation using patented, pre-charged R-454B Quick Connect line sets — no vacuuming or specialized HVAC tools required.
- Included DIYPro cable eliminates the need for electrical conduit, simplifying the wiring run between condenser and air handlers.
- Follow Me function on the included remote tracks the temperature near you for more consistent comfort in each zone.
- SmartHVAC app control with Amazon Alexa and Google Assistant compatibility lets you manage each zone from your phone or by voice.
- Ceiling cassette air handler(s) mount flush between 16" ceiling joists for a low-profile, space-saving install with advanced filtration and an Elevation function for easy filter access.
