This Whirlpool 12,000 BTU Through-the-Wall Air Conditioner helps you keep your space feeling just right. It's great for cooling down rooms up to 550 square feet, and it also pulls moisture out of the air to make things more comfortable. You can pick from different modes like cool, dry, fan, or auto, and choose from three fan speeds to get the airflow you want. Plus, it has handy Eco and Sleep functions to help save energy, and a 24-hour timer lets you set it to turn on or off whenever works best for you. Adjusting the temperature is a breeze with its wide range, and you can easily direct the airflow where you need it with the 8-way louvers. Cleaning is simple too, thanks to a filter that's easy to reach. If the power goes out, it's smart enough to restart itself once the power is back. It even comes with a trim kit, making installation into a standard wall sleeve straightforward.

Whirlpool 12,000 BTU Through-the-Wall Air Conditioner

Great AC, Cools Two Rooms with Eco-Friendly Feature!

This Whirlpool AC is a solid choice if you need to cool down a couple of rooms. While installation requires a professional due to the 230 voltage, it's worth it for the effective cooling. The eco mode is a lifesaver for energy efficiency and makes it super easy to manage when things get really hot.
