Description
This MRCOOL Olympus 4th Gen ductless mini-split system pairs a 36,000 BTU multi-zone heat pump condenser with four independently controlled Ceiling Cassette indoor air handlers (12,000 BTU + 12,000 BTU + 9,000 BTU + 9,000 BTU), giving up to four rooms their own heating and cooling zone from a single outdoor unit.
Highlights
- Four-zone, single-condenser design — one 36,000 BTU outdoor condenser (model MULTI5-36HP230C-O) supports up to 5 indoor units, so all four air handlers in this configuration run independently from one outdoor unit.
- High-efficiency inverter operation — SEER2 ratings up to 24 and HSPF2-4 up to 9.5 help lower cooling and heating costs across all four zones.
- Reliable cold-climate heating — rated to operate in outdoor temperatures as low as 5°F, so the system keeps heating through cold winter conditions.
- Ceiling Cassette indoor units throughout — all four zones use ceiling cassette air handlers (12,000 BTU + 12,000 BTU + 9,000 BTU + 9,000 BTU), for a consistent look and installation approach across every room.
- Smart, flexible control — operate the system from the MRCOOL SmartHVAC app, the included remote control, or hands-free through Amazon Alexa and Google Assistant.
- Built-in safety and efficiency features — sleep mode, auto restart, and built-in refrigerant leak detection support safe, efficient day-to-day operation.
Details
Avermont Direct is an authorized MRCOOL dealer. This 4-zone Olympus 4th Gen system is backed by a 7-year limited compressor warranty and a 5-year parts warranty when the unit is registered and professionally installed. With 4 independently controlled ceiling cassette zones totaling 36,000 BTU, it suits homes or offices that need separate, zone-specific temperature control across four rooms or areas from a single outdoor condenser. As with all ductless mini-split systems, installation must be performed by a licensed HVAC professional.
