This air conditioner is awesome! Works as described and is quiet. House feels so cool now.

I ordered an ac until. It was delivered 3 days later that specified and when we opened it today it is scratched and used. There’s a corner bent and the box has been opened. There’s no styrofoam surrounding it. I called to ask why I received a used one and was told a new one would be sent in 4-5 days. I was told I would receive 10% off a future order. I will NEVER order anything from Wayfair again.

Wow! What a great step-up from my previous air conditioner. This is much quieter and much more powerful. Just got it going today but I've enjoyed the last few hours. It works so well.

[This review was collected as part of a promotion.] I have installed this cooling unit in an external building. The installation process was straightforward. The unit comes with a remote control, allowing for easy and quick adjustments to the settings. It is designed to cool a room or area up to 350 feet, which is suitable for my requirements. I would appreciate if it had a heating feature, but the unit I have received does not include this feature.

[This review was collected as part of a promotion.] The Keystone 12000-BTU Window AC is a **strong budget contender** for cooling medium-sized rooms. Its core strength is delivering powerful, effective cooling at an attractive price, enhanced by the convenience of a remote control. However, it comes with the expected trade-offs: noticeable compressor noise (especially on high settings), potential for vibration if not installed perfectly, basic build quality on accessories, and a less precise thermostat. If you prioritize raw cooling power and value over whisper-quiet operation and premium features, this Keystone unit is a very good choice.
