  7. Whynter - ARC-1230WNH 600 Sq.Ft Smart NEX Inverter Portable Air Conditioner 12000 BTU Heater - White - Front_Zoom
    Top comment

    "Great portable air conditioner/heat pump...Great portable air conditioner and heat pump. Use the air conditioner to keep my bedroom cooler at night. ...I got this mostly for the powerful cooling but having the heater function for colder nights is a must have. I love this portable air conditioner. Helping us through this crazy summer heat."

    Product Description

    The Whynter ARC-1230WNH Inverter Dual Hose Portable Air Conditioner and Heater has the highest cooling and heating BTU (14,000 ASHRAE / 12,000 SACC) in the market. The cooling power you need to cool, dehumidify or circulate the air in up to 600 sq. ft of space. Smart functionalities include the NetHome Plus app to control your portable air conditioner through Wi-Fi from virtually anywhere. You can also control it with Amazon Alexa or Google Home voice assistant. Intelligent features such as the 24-hour Timer, Sleep Mode, Auto restart, Self-Diagnosis, Express Run Settings, Schedules, and Filter Check Reminder Light. As pioneers in the air comfort industry, we are introducing the next-generation Inverter Technology currently only being used in high-efficiency ductless mini-split air conditioners to our NEX line of portable air conditioners. The variable-speed system allows the compressor to optimize efficiency and power consumption together while maintaining a specified output. The advantages of inverter technology are estimated 40% – 50% in energy savings, 2 times quicker to achieve desired temperature, quieter operation, minimized temperature fluctuations, no voltage peaks from the compressor. The innovative two-hose-in-one design and the sealed bottom structure ensure no heat leakage. This cooling setup extracts and exhausts air from the outside, so the indoor space reaches an independent and balanced cool air circulation. As a result, the entire room can be cooled down quickly and effectively. The noise level is as low as 47dB(A) in low fan speed, almost as quite as a library. You can control your portable air conditioner anywhere with the NetHome Plus app for Android and iOS and make your home comfortable even before you arrive. Also, you can use Amazon Alexa or Google Home voice assistant to operate the air conditioner.
