## Questions & Answers

**Q: How do you secure the air conditioner to the bracket? What keeps it from falling off?**
A: The value of the bracket is reducing the possibility that the air conditioner tips and drops to the ground, especially during installation.  Most air conditioners are designed to be supported by the window sill and the window itself.  If installed properly, the air conditioner also rests on the bracket but is not attached to it.

**Q: I have no exterior window sill? Where would you mount the bracket inside? On the interior window sill or inside track of window?**
A: If you have no exterior window sill, you would have to drill and mount the bracket on your interior window sill.

**Q: Will this bracket work on sliding windows**
A: Yes. I am using it in a sliding window. The directions are pretty bad and it's a pain to install. The directions tell you to measure so it's installed in the middle of the opening but I had to take it out and then reinstall it tight to the wall side of the window frame. There's a lot of guesswork involved in the installation. In the end it works and seems sturdy enough.

**Q: Will this bracket work for an air conditioner that slides into a cabinet?**
A: Yes—it worked perfectly for an LG “LW1216ER” unit.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Sturdy, fast and easy to install!
*by A***A on August 9, 2022*

The hardest part about installing this bracket was drilling the holes - but that was because of how I installed it.I wanted my AC unit "outside" of my window, so I could still shut the window. I did this by creating a plywood "baffle" that I could insert inside the recesses for the screen. I removed the screen, put the baffle in, then used putty tape to seal it up around the edges.To mount the AC unit and bracket this way, meant I had to drill and mount the bracket on the outside brick/block "sill" of my window. So with some research, I settled on using some carbide bits to drill with, and special "blue" anchor screws. I quickly found that:a) you want to drill the block "dry"b) you want to periodically use canned air (or a compressor) to "blow out" the hole as it fills with dustIf you don't do those steps - you end up with the drill only going so far, then not going any further. So drill, blow out the hole, drill some more, etc - until you get to the depth needed.But other than that difference, I followed the instructions just as they were written, and things went together really well and fast. I've had the bracket up for about 2 weeks now, and it works great. It only took a couple of hours to install (I took my time, as I didn't want to mess up the block), then a few more to make the baffle (a week or so later, I caulked it, painted it, then re-installed it properly - but I did use it for a week without all of that).The only other extra thing I did was add a couple of L-brackets to the holes, to keep the unit from potentially "sliding backwards". Overall, the install turned out great, and I'm very pleased with the product.

### ⭐⭐⭐⭐⭐ Excellent design low cost and safest option
*by M***N on August 17, 2025*

Second year using our two ac unit brackets, perfect, love them. I never liked relying on the window sash to hold the heavy units in place, ESPECIALLY on second floor over doorway or pedestrian walkway!. I bought another one this year for my in-laws. Also eliminates risk of window and sill damage:)Highly recommend!

### ⭐⭐⭐⭐ Does the job small or large air conditioners.
*by L***  on July 2, 2025*

I give this item 4 stars because it’s good quality and very sturdy. However, the directions are terrible. I am not super well versed with assembly but I know my tools. I needed to go into my own tool box for better wrenches and screw drivers of different sizes. The directions are basically pictures/ but not so good. It took me 3x to assemble and reassemble for correct size. As you can see it’s perfect and even for this small air conditioner it’s steady and straight. Yes, I’d buy it again for my other windows. Just be prepared with patience and extra tools.
