Description
The MRCOOL DIY 5th Gen 48,000 BTU 6-Zone Ductless Mini-Split Condenser is a true do-it-yourself system, letting you heat and cool up to 6 separate spaces (up to 2,000 sq. ft. combined) without hiring an HVAC professional, and this configuration pairs it with 6 Wall Mount indoor air handlers (12K + 9K + 9K + 9K + 6K + 6K).
Highlights
- Patented, pre-charged Quick Connect line sets (filled with R-454B refrigerant) let you skip the evacuate-and-charge process, so the whole system can be installed yourself
- Rated up to 21.8 SEER2 and HSPF2 of 10 for efficient year-round heating and cooling
- The included DIYPro cable removes the need for electrical conduit runs
- Each Wall Mount air handler includes a Gold Fin condenser coating for added corrosion resistance (a plus in coastal climates), plus Follow Me temperature tracking and Dry Mode humidity control
- Control the system by wireless remote, the SmartHVAC app (iOS/Android), or voice commands through Amazon Alexa and Google Assistant, including Follow Me tracking on the remote
- Intertek listed (5031495) with a 5-year parts warranty, a 7-year compressor warranty, and a Limited Lifetime Replacement warranty available through the MRCOOL Care Program
