This MRCOOL DIY 5th Generation 2-zone ductless mini-split system pairs a 27,000 BTU outdoor condenser with two identical 9,000 BTU wall mount air handlers, so you can heat and cool two separate rooms without hiring an HVAC professional. The condenser is rated 23 SEER2 and 9.5 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.
- Wall-mounted air handler(s) include a Gold Fin condenser coil for added corrosion resistance, a plus in coastal environments, plus Dry Mode for humidity control.
