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

Did the job

I live in an RV. I CANNOT DRILL INTO MY WALLS. This support is perfect for RVs.

The A/C support bracket seemed to be sturdy and well made. The double bracket could easily hold up the weight of a fairly large AC. The design seems pretty well thought out and could work in many different applications where a support bracket it required. That one caveat that I mentioned in the title is that It didnt work out with the type of vinyl siding on our house, so we had to return it. However, I cant really say its a fault in the design of the bracket. Our house has large, thick vinyl siding panels that imitate the look of wooden shingles. They are very flexible and stick out from the side of the house quite a bit. Ill include a picture below. While I was setting up the support bracket, I mounted it to the window and rested the rubber feet up against the house. When applying some weight, I noticed that the feet were pressing on the siding a great deal, causing it to flex inward. I was afraid that it might crack the siding over time from bearing the weight of the AC. Also, the vinyl siding is very flexible and springy, so the support feet didnt really have any available surface for which to be firmly planted against. So, Like I was saying, the bracket is solid and will work for a variety of applications, but if you have siding like we do on our house, it might not work out for you.

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.

No assembly instructions. Because there are no instructions in the box or online (the link for instructions on the Amazon.com is missing) Ive been guessing on how to assemble it. But I have extra parts leftover I am not sure what purposes those parts are for. Per the photos, it would appear that I am missing at least 2 longer bolts, 2 washers, and 2 nuts. It seems to be a solid metal bracket so it got a star for the heavier gauge bracket parts. Amazon forces you to post a minimum of 1 star. I have someone coming over to help me try to install it and the 6k btu air conditioner. I am keeping my fingers crossed that we can at least macgyver it. UPDATE: I bought a second one and it came with instructions. It took two of us 3 hours to install The first air conditioner (6000 btu) into a jalousie window. The second one went in after about 2 hours with 5000 btu unit. To use this bracket in jalousie windows is not for temporary installation I.e. A renter. But overall, it is a good racket once you know how to assemble it so I will raise the rating to 3 stars. But without instructions, this can be very frustrating to use.

This bracket is good. Easy to assemble and install. But, it left a large gap under the air conditioner that had to be filled with a 2 x 3 and 2 1/4 x 2 1/4 air conditioner foam.

One thing to note is that if your AC unit is not flat on the bottom, then it wont sit on the brackets very well. You must install it with a slight downward angle away from the window otherwise, the unit wont drain the condensate very well. The other issue is that the bolt that attaches the feet to the lower braces needs to have a sleave installed between the bracket sides so that sufficient fastener pressure can be applied to lock the feet in. As it is now, it just crushes the sides.

Great for window a/c of any sixe.

Bought 2 of these products to support 2 - 10K Frigidaire Window A/Cs. They are constructed quite well and are very strong. Each of my A/C units weigh approx 115 lbs. Once setup correctly, these supports not only fit nearly perfect n my windows, but also support the units quite easily! While the feet set against the vinyl siding and proper 5-8 deg (for water drainage) is noticeable. You may have a few gaps to fill, but that can be accomplished quite easily. I use 1/2 Styrofoam Pipe wrap and cut to fit. No complaints and the units have been running without incident for a month.

Ive got two of these. Im not unhappy with them overall, but they are quite difficult to set up. The feet have some trouble connecting with any exterior wall that has siding (which is pretty much every wall). The only way I can get the feet to connect with the wall is if the feet are positioned very inward, but then stability is horrible. Thats the main reason for the 3-star review. They work, but they take some fiddling and you for sure have to screw them into the windowsill directly. They come with spacers to help line up the screwed surface with the window frame so your A/C doesnt sit tilted inward. The provided screws will work for one install, they strip on the heads very easily, but they are a standard size so your local hardware store will have replacements for next year. Also, word from the stupid, careful not to pinch your fingers in this as it does fold completely and with zero resistance so it can collapse (when not mounted) and pinch your fingers easily. Its also very heavy and so the pinch has a real bite to it.
