This MRCOOL Olympus 4th Gen system pairs a 48,000-BTU, 4-zone outdoor condenser with four ceiling-concealed ducted indoor air handlers (9K + 9K + 9K + 9K), giving each zone independent, app-controlled heating and cooling with a SEER2 rating as high as 24 and reliable operation down to 5°F outdoor temperatures.
Highlights
- 4-zone, 48,000 BTU total capacity — independently controls up to 4 rooms from a single outdoor condenser.
- All four indoor air handlers are the ceiling-concealed ducted style, sized 9K + 9K + 9K + 9K, for a consistent look and installation approach across every zone.
- Control every zone from the MRCOOL® SmartHVAC app over Wi-Fi, the included remote/wired controller, or hands-free with Amazon Alexa and Google Assistant.
- Sleep mode, auto restart, and refrigerant leak detection help the system run safely and efficiently with minimal attention.
- Uses R-454B refrigerant, a lower global-warming-potential option, and is Energy Star Certified.
- Backed by a limited lifetime warranty plus a 7-year compressor and 5-year parts warranty when the system is registered and professionally installed.

Details
Avermont Direct is an authorized MRCOOL dealer, and this Olympus 4th Gen 48,000-BTU 4-zone system is built for whole-home or multi-room comfort where a single outdoor condenser needs to serve several spaces at once — each of the ceiling-concealed ducted indoor units in this configuration (9K + 9K + 9K + 9K) can be set to its own temperature. The system carries a limited lifetime warranty along with a 7-year compressor warranty and 5-year parts warranty when registered and professionally installed. As with all MRCOOL Olympus systems, installation should be performed by a licensed HVAC professional.
