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

    "Cooling and heating performance...Cooling works excellent.however,the heating mode barely works due to ambient temp concessions that dictate it's operations...Easy to install, fast cooling in my living room and my family enjoy to have portable while waiting our central unit repair."

    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.

  7. Honeywell - 525 CFM Portable Evaporative Cooler - White - Front_Zoom
    Top comment

    "Keeping Cool...Good points are that it does cool a certain size room for cheaper than running the regular AC. ...Great for cooling mid sized room...Simple to use, does a good job of cooling a mid sized kitchen and living room area. "

    See all customer reviews

    Product Description

    The Honeywell 525 CFM indoor evaporative air cooler offers an energy efficient cooling option when the air is hot with low humidity, such as desert areas like the southwestern United States (recommended humidity level is 60% or less for maximum efficiency). Honeywell evaporative air coolers do not require power hungry components like compressors. The low power consumption (only 288 watts) translates into significant savings on energy bills compared to using air conditioners. Just unpack, add water/ice, place near open door or window, plug it in, and use. This unit is ideal for indoor use in open environments with adequate cross ventilation up to 491 square feet. Four fan speeds and oscillating louvers evenly distribute cool air through the honeycomb cooling media while the carbon dust filter cleanses the air. For those living in more humid climates, consider portable air conditioning units or window air conditioners.
