✅ Top #1 Pick: Frigidaire Window AC Review
The Frigidaire window AC can save you money this summer.
Energy Star Certified unit, it has an energy efficiency ratio (EER) of 10.9 — very good compared to others!
Power: 8,000 – 12,000 BTU
Rooms: 300 – 450 sq. ft.
As a top rated window ac it comes equipped w/ adjustable temperature controls which lets you set a fixed temp (instead of increase/decrease power). Using the remote control, simply set your desired room temp and let the AC do the rest!
For the lower price, the Frigidaire window AC is relatively quiet.
Noise level (dB): 56 – 60 decibels
(If you need one quieter, the Haier AC below might be a better fit)
Very easy install too — Takes only 5-10 mins.
built-in dehumidifier, LCD remote control, multiple fan speeds, on/off timers
Overall it’s a good, affordable unit w/ all the basics you want.
The Friedrich Chill Series window air conditioners are luxury units — powerful cooling and built for efficiency.
Available in 8 sizes (10,000 and 12,000 BTU are the most popular).

Each window-mounted unit is Energy Star Qualified.
They come w/ new “MoneySaver Mode” — this drastically lowers energy consumption by running the fan + AC motor at the same time.
Running both simultaneously also lets the AC run at slower speeds (therefore saving electricity).
Another feature is its quiet operation. Buyers confirm that Friedrich Chill units operate 50-70% quieter than typical window air conditioners.
If you’re looking to save energy and need it quiet (for a bedroom?), this is the one you want.
Downside is the price.
The Friedrich Chill air conditioners are expensive, but high-quality + very good buyer reviews.
The Haier Serenity Series is quickly becoming a best seller on Amazon.

AC Power: 6050 BTU
Noise Level: 42 – 53 dB
Room Size: 150 – 250 sq. ft.
To help reduce noise, the Haier Serenity uses a compressor blanket and customized air-flow.
Expect a 10-15% reduction in noise (compared to other units).
Haier ESAQ406P also features a built-in dehumidifier, LED remote control + fast cooling.
It’s expensive for a 6000 BTU unit, but I think it’s the best quiet window air conditioner that’s somewhat affordable.
Lots of happy buyer reviews too.
