Keystone Home Comfort

Did you know our top-selling category is Through-the-Wall ACs? These units are designed specifically for homes with a wall cutout, and trust us, there’s a reason for that.

We’ve seen people try to make window ACs work in these spaces before, but it’s just not a reliable long-term solution. The right fit makes all the difference when it comes to performance, efficiency, and comfort.

Your home deserves a unit made for your space, not a workaround. Shop the right Through-the-Wall AC for your setup https://vist.ly/57x6f

First time installing a window AC? We provide a detailed manual with every unit to keep setup a breeze, so you can start feeling that breeze sooner.

Here are some of our top tips for installing a new window AC:

1. Always have a friend help. This is a two-person job, so don't be brave.

2. Double-check your insulation and make sure there are no gaps. A quick way to test is by looking for any light coming through around the unit.

3. Choose a window that's central to the room and free from furniture obstructions. Most importantly, don't give up your favorite view.
