Other key features we liked included a large-capacity dehumidifier that can remove up to 1.5 pints of moisture from the air per hour. Auto cool and energy saver modes help you quickly cool space and reduce consumption. A sleep mode shuts off the air conditioner when your desired temperature is reached. Plus the included remote makes it easier to control this unit or you can opt to use the LED control panel to manually change the temperature and settings. You may also want to think about comparing other air conditioners in our best window air conditioner lineup.

Why We Like It – Haier Serenity Series Quiet 6,000 BTU Window Air Conditioner

The Haier Serenity Series Quiet 6,000 BTU Window Air Conditioner is perfect for cooling up to 150 sq ft making it a top pick among those who need it, thanks to the sleep mode it has a high energy star rating. With this unit being one of the quietest window air conditioners, you’ll be able to enjoy being in your home without dealing with a loud, annoying AC unit.

  • 4 functions
  • Dehumidification up to 1.5pph
  • Remote controlled
  • Freezes up


Some reports indicate while the ultra-quiet operation of the lower fan speeds resulted in slower cooling speeds the air controller can easily be turned up to enhance the cooling speed at the cost of the noise level. While sleep mode auto is on it will shut off when the room air reaches the desired temperature, but that’s a feature with most window air conditioners


Included is a window mounting kit, and easy to use control panel that includes options like dehumidification, and four cooling and fan speed settings round out some of the top features. It is the best air conditioner you can buy. With a four-way air conditioner, it makes others look a bit primitive by comparison such as the Midea U Inverter Window Air Conditioner. Also comes with a 24-hour timer so you could shut it off when you leave for work and have it come on when you come home. Once installed some have said the Haier Serenity Series Quiet 6,000 BTU Window Air Conditioner is a quiet window unit that they can ignore when not in use.

Although, for a smart A/C unit, you’ll want to read our Frigidaire FGRC1044T1 smart window air conditioner review and our Hisense AP10CW1G 10000 BTU Wi-Fi smart air conditioner review.

With free shipping in the United States and coming in lighter than the Friedrich Chill CP06G10B 6,000 BTU Window Air Conditioner, it’s easier to install on your own without help. Unfortunately, it isn’t as cheap as the Frigidaire FFRA0511R1E 5,000 BTU Mini-Compact Air Conditioner or the Frigidaire FFRA0511R1 so you’ll need to make sure the Haier ESAQ406T does everything you need it to.

Haier Serenity Series Quiet 6,000 BTU Window Air Conditioner Wrap Up

When it comes to window ac you’ll want a window unit that is a quiet ac unit because you won’t want the unit to be in the center of the room, even if it has a digital temperature screen. The Haier Serenity Series Quiet 6,000 BTU Window Air Conditioner has the claim of being the quietest window ac unit on the market, while we can’t directly verify that claim the comfort of quiet air-cooled to our liking is something everyone wants. All that said, some have recommended the LG LW8016ER 8,000 BTU Window Air Conditioner over this one.
