Whynter ARC-1230WN review

The ARC-1230WN is Whynter's NEX inverter model, and its 12,000 BTU SACC rating is the highest figure on this list. SACC is the Department of Energy's seasonally adjusted rating, which runs lower than the older ASHRAE number, so it is the fairer way to compare units; the ASHRAE figure here is 14,000 BTU. Whynter rates it for spaces up to 600 sq ft and lists a dehumidifying capacity of 87 pints per day. The hose-in-hose design keeps intake and exhaust in one window connection, and the louver swings automatically through 80 degrees. Whynter lists noise as under 42.5 dB on low, 49.5 dB on medium and 56.5 dB on high, with five fan speeds. Smart control works through Amazon Alexa, Google Home or the NetHome Plus app, and there is a 24-hour timer, sleep mode and auto restart. It costs $659.99 on Whynter's own store. The trade-offs: there is no heat mode on this version, and the maximum hose length is 47 inches, so place it close to the window.
