Description
The Daikin 2MXT18AVJU9 is a 1.5-ton (18,000 BTU nominal), 2-zone outdoor heat pump condenser from Daikin’s Aurora cold-climate line, delivering up to 17,200 BTU cooling and 18,000 BTU heating capacity. It supports two independently-controlled indoor units from a single outdoor unit, letting each zone run its own temperature setting.
At the core is a Daikin inverter-driven “variable speed” swing compressor that automatically adjusts output once the set temperature is reached, rather than cycling on and off at full capacity, for quieter, more efficient operation. The system runs on R-32 refrigerant and delivers up to 21.0 SEER2, 12.0 EER2, and 10.0 HSPF2 efficiency (rating varies with the specific indoor units selected), with a cooling operating range of 14°F to 115°F and heating operation extending down to -13°F for reliable cold-climate performance — a base pan heater accessory is required to achieve heating below 5°F.
The compact outdoor cabinet (29-1/2″ H x 34-1/4″ W x 12-5/8″ D, 147 lb) uses anti-corrosion treatment on the heat exchanger for long-term outdoor durability, and 1/4″ liquid line connections keep piping straightforward. A Priority Room Setting lets one zone take precedence when both units are running simultaneously, and the system automatically returns to its prior operating settings after a power outage. Additional convenience features include Night Quiet Mode, Quick Warming function, Cool/Heat mode lock, self-diagnosis, and a wiring error check function.
Runs on 208/230V single-phase power. Requires two compatible Daikin multi-zone indoor units (sold separately), a line set, and drain tubing for installation; a base pan heater is optional but required for heating below 5°F. Backed by a 12-year limited parts warranty with online registration; installation by a qualified, licensed HVAC technician is required to maintain warranty eligibility.
