Description
This MRCOOL DIY 5th Generation 3-zone ductless mini-split system pairs a 48,000 BTU multi-zone condenser with three wall-mount air handlers (18K + 18K + 6K BTU), installed without hiring an HVAC professional thanks to the pre-charged DIY QuickConnect line set.
Highlights
- Three-zone coverage — one 48,000 BTU condenser powers three independent wall-mount air handlers (18K + 18K + 6K BTU), each zone controlled on its own schedule and temperature.
- No HVAC professional required — the patented, pre-charged Quick Connect line sets (filled with R-454B refrigerant) let you skip evacuating and charging the system yourself.
- DIYPro cable included — future-proofs the installation and eliminates the need for electrical conduit.
- Smart control options — manage the system with the included wireless remote, the SmartHVAC app (iOS and Android), or hands-free through Amazon Alexa and Google Home/Assistant.
- Follow Me tracking — each remote monitors the air temperature near you to help maintain consistent comfort in that zone.
- Gold Fin condenser coil — offers extra corrosion resistance, a benefit in coastal environments.
Details
Avermont Direct is an authorized MRCOOL dealer.

It suits a home or workspace needing independent temperature control across three separate rooms — for example, an 18K + 18K + 6K BTU combination sized to rooms of differing size — without the cost or wait of a professional HVAC installation.
