Description
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.
Details
Avermont Direct is an authorized MRCOOL dealer, and this 55,000 BTU DIY 5th Gen 3-zone system is backed by MRCOOL's stated 5-year parts warranty, 7-year compressor warranty, and Limited Lifetime Replacement warranty for owners enrolled in the MRCOOL Care Program. It suits homeowners looking to independently heat and cool three separate rooms or living areas — sized 6K BTU, 24K BTU, 24K BTU respectively — from a single outdoor condenser, without scheduling a professional HVAC installation.
