Description
This MRCOOL DIY 5th Gen 4-zone ductless mini-split system pairs a 55,000 BTU outdoor condenser (rated for up to 6 zones and up to 2,290 sq. ft. of combined coverage, SEER2 22 / HSPF2-4 10.6) with four 9,000 BTU wall-mount air handlers.
Highlights
- Four 9,000 + 9,000 + 9,000 + 9,000 BTU wall-mount air handlers give you independent temperature control in four separate rooms.
- Patented DIY Quick Connect line sets come pre-charged with R-454B refrigerant, skipping the evacuation/vacuuming steps of a traditional install.
- DIYPro cable eliminates the need for electrical conduit, and the Gold Fin condenser coil resists corrosion in coastal climates.
- Follow Me function on the wireless remote tracks the room's actual temperature for more consistent comfort; Dry Mode helps control humidity.
- Control each zone from the SmartHVAC app or hands-free via Amazon Alexa and Google Assistant.
- Backed by a 5-year parts warranty and 7-year compressor warranty, with a Limited Lifetime Replacement warranty available through the MRCOOL Care Program.
