Alpine Hardware Premium Heat Pump Drillless Drill-Less Window Air Conditioner & Heat Pump Bracket - Window AC Support - Supports Air Conditioners Well Over 200 lbs. - No Drilling 2023 Model

As the title states, this is one of the worst purchases I have ever made. From a design and metal quality standpoint it’s fine, but trying to put this thing together took literally hours, and that was with two people. The included directions might as well not exist, and the video for it is also an absolute disaster, it should banned from YouTube. There was not enough hardware included to build it properly, so I was only able to use 75% of the included screwsolts. I have absolutely 0 clue what its actually doing in my window right now or if it’s even really holding up the air conditioner. I was able to eventually cobble it together, but that was only after taking it apart and putting it back together about 5x... Both the directions and the video show you how to build the item, and then in the following steps essentially tell you to completely take it apart again. • If you hate yourself enough to buy this item, or you are really desperate and live in an apartment like I do where you can’t readily drill into your windows, I advise watching the video IN FULL (don’t bother reading the directions they were written by someone with wet brain), from start to finish, several times.... And while building this thing, if you find yourself with not enough hardware, pray. Just pray and believe and hope that this thing will stay together and not come crashing down and take out the persons AC who lives below you.

Although it says it fits 24 to 38, I installed it in my 21 window and it fits securely for my smaller A/C unit. Installed through the window and against the inner trim. I bought 4 total, and the others are mounted in the actual window channel, which eliminates the 3 air gap under the bracket that you need to seal up to prevent hot air from coming back in. Not sure what other customers were complaining about with the quality, like the picture of the 45 degree legs dangling straight down. I suspect they had the support legs installed backwards. There is a lip on one end of the support legs to prevent them from dropping down. Not sure why anyone would drill holes into their window sills, unless it was a permanent installation. But if you need A/C year round, a unit installed in the existing heating system is the way to go. But if you only need it in the summer months, these are the brackets to use and not make your window sills look like crap for the other 8 months of the year. It may be a little overkill for an 8000 BTU unit, but it is solid.

Wish this had some adjustability to widen out. Still works very well and gives great peace of mind as A/C is on second story. Some bolts are a little tricky to reach and you may have to press legs up to tighten after A/C installed. Overall very pleased. Its very heavy duty. As others have said watch the video and it will help. Probably took about 1/2 hour to install.

Since the written instructions for the two-arm, heavy duty version (drilling required) of this bracket are almost impossible to follow, a good installation video is needed, but there are a lot of problems in Alpines installation video. Mainly, the sections showing how to install the connector bar are pretty screwed up - it shows the long hex bar being inserted at different locations. Also, in the section for the final installation (at 2:52 of the video), the connector bar magically disappears altogether. More detailed comments, with many of the flaws in the video, can be found at the YouTube version of this video (the two arm, heavy duty, drilling required version). Alpine did a really sloppy job with this video.

Solid product, suggest revision of sizing instructions. Would have been helpful to test size before tightening all bolts.

Dislike directions. Definitely sturdy. But now my unit leaks a lot down side of my wooden house all day long.

In short, this wont fit windows with an outside ledge that extends farther out than the rest of the exterior. It seems that an exact angle is needed between the two arms to provide support, and the window ledge prevented that from happening. The rubber pad wanted to rest exactly on the bottom of the ledge and couldnt get any support without immediately falling. I live in a century-old brick building where each window has a stone ledge that extends out about three inches on the outside, and it about 4 inches high. No matter how I positioned this bracket I could not get the rubber pad to rest properly on the building. I repositioned and re-drilled three times but no amount of adjusting would let the rubber pad sit properly. All my measurements were correct from the listing and the directions, however because of the ledge none of the holes on the horizontal part of the bracket would allow me to mount it properly. It seemed that I needed the horizontal arm to be a little longer with one more mounting hole for me to be successful. The bottom arm has a metal piece at the top that juts out and that prevented me from using any of the holes. I assume this is because it needs a certain angle to provide support, however none of the angles or holes worked for me. Three stars because it seems like a really quality product, but I feel like ledges are fairly common and I expected this to have no issue. ---------------------- A tip for everyone: Also they have a YouTube video with installation instructions that is worlds better than the included directions.

This bracket was purchased to hold a 80lb Kenmore A/C unit. We came into two issues. Our first issue was that the surface of the mount is slick metal. When the A/C unit asks with installation to have a slight outward tilt so that condinsation call fall outside the window. We noticed the unit was also built metal so it wanted to slide. There is no backing plate to hold in place and no items such as rubber spacers to help A/C from sliding around. So we took a board and cut it to the size of the A/C unit and screwed it to the bracket to give it less a change to slide. The next issue was the mounting screws. We followed the directions and pre-drilled the holes to mount to the window. Once installing the screws with a half dead almost powerless drill the bolts snapped. Right where the threads start. We decided to try another screw and once again it snapped. We then went to the hardware store and purchased the same size standard screws for 35cents each. We then installed bracket with no problems. Putting the provided screw next to a standard screwed we purchased you can right away notice the quality difference of the metal being used. The strength of the bracket itself seems strong. Once everything was installed I put some good amount of my weight on it and it held strong. For the price and quality I would have to say you should try another product or plan to grab some quality 35cent screws and figure a way to keep unit from sliding.

Was able to setup in 30 minutes, Placed parts on a flat service and laid out as if assembled, then followed the instructions. The Leg supports took the most time in the setup, primarily to determine where they should be located. Do think more pictures should be included in instructions reflecting a step by step pictorial, especially for the leg supports.

Air conditioner support.
