This MRCOOL DIY 5th Gen ductless mini-split system pairs a 55,000-BTU multi-zone condenser (up to 2,290 sq. ft. of combined coverage) with three wall-mount indoor air handlers rated 6K + 24K + 24K BTU, and it installs without hiring an HVAC professional thanks to MRCOOL's pre-charged Quick Connect line sets.
Highlights
-
No HVAC pro required — the DIY 5th Gen system uses patented pre-charged Quick Connect line sets filled with R-454B refrigerant, so there's no evacuating or charging the line during installation.
-
Whole-home zoning — the 55,000 BTU condenser supports up to 6 indoor zones and up to 2,290 sq. ft. of combined coverage, with this system's three wall-mount air handlers (6K + 24K + 24K BTU) covering their assigned rooms individually.
-
Smart control — manage schedules and modes from the SmartHVAC app (Apple/Android) or hands-free through Amazon Alexa and Google Home integration, in addition to the included wireless remote for each indoor unit.
-
Follow Me temperature tracking — each remote reports the temperature around it so the connected air handler adjusts airflow to keep that spot comfortable, with Dry Mode available to reduce excess humidity.
-
Conduit-free wiring — the included DIYPro cable removes the need for electrical conduit runs, and the outdoor unit's Gold Fin condenser coil resists corrosion in coastal or humid climates.
-
NEEP-listed zone(s) — this system's 24K BTU indoor air handler(s) carry NEEP ccASHP Listed certification.
