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

I just installed this over the weekend. Its pretty rickety (my unit is 10,000 BTU and around 80-100 pounds) and although you dont have to screw anything into the outside wall, you do have to screw 3 holes into the windowsill. Luckily, we live in an extremely old house and my landlord said before we moved in that he needs to replace the windowsills at some point, so when I asked him if I could drill, he just shrugged and said, Why not? Installation is fairly easy, but I found myself having to be extremely delicate with the unit itself on top of the support. It rocks slightly from side to side which made me worried that my unit would fall if I didnt take a ton of care. I had one other person helping me inside, and somebody outside to help guide the unit into place so that we wouldnt have to slide it at all. At the end of the day, this was extremely cheap compared to the other brackets (which I suspect are almost the exact same thing). At the time of purchase, it was half the price of the equivalent product at Lowes. The level was helpful (though I double checked with another level when I got the unit in). And hey- it works, albeit rickety. Worth the money I paid, but not a dime more.

The Alpine Hardware Universal Window Air Conditioner Bracket may work in some cases but it has some serious design flaws and was completely useless for me. Installing a window unit in a garage workshop, I thought the bracket would provide solid support. The first problem that the long screws that connect the legs to the platform are impossible to tighten enough to keep the feet against the outside wall. The legs are just enough narrower than the platform arms that the legs swing free. I was concerned that vibration from the unit would cause them to fall and the weight of the AC would cause it to fall outside, ruining the AC and the window frame. To fix that I made a trip to the hardware store and bought four sets of screws, washers, and lock nuts. That at least kept the legs in place. (See photos) The next major flaw is the frame causes the AC to sit ½” above the bottom of the window frame. That means you’ll need to stuff a lot of foam (not included) to seal the large gap underneath the AC unit. The final flaw is that there is no simple or obvious way to attach the unit to the bracket. Normally the AC came with L-brackets that attach it to the windowsill, but the brackets raised everything so far above the sill that the included brackets wouldn’t reach. The side curtains aren’t sturdy enough to hold the AC in place so a bump to the front or back of the AC would send it crashing to the floor/ground. Rather than make another trip to the hardware store to work around the problems with the bracket, I cut a shelf for the sill from a 2x4 and build a small frame outside to help support the unit. I made it wide enough to attach brackets to keep the AC in place. If after reading this you decide to purchase this bracket anyway, be sure to watch the assembly video several times. It will save you a lot of trouble. The one-page, tiny print instructions in Chinglish are difficult to read and understand and they do not follow the “simple” steps shown in the video. Any product that, out of the box, requires that many updates, fixes, and work-arounds is not worth the time or the money.

We installed this on our RV to hold a window unit. It worked great, and even survived a direct hit from hurricane Ian at a category 4, it held strong with the unit in place. Hated spending $75 for it, but wow, cant complain now.

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.

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.

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.

So far its been working well

I bought four units and putting the first one together took awhile. The directions were minimal and pictures didn’t help much. The following 3 were easy since I became an expert at it. Installed, they are working as advertised. It’s a smart system. Just be prepared for a lot of assembly.

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.

I needed a drill-less bracket for my AC and chose this item. Although you dont need to drill the bracket into your outside wall you still need a handful of tools to assemble the bracket itself properly. The instructional video has a lot of unnecessary steps which will require you, as shown in the video, to make constant adjustments to the bracket. For an instructional/installation video there is way too much trial and error. The first step of the video asks you to measure the distance from the outside wall to your window frame and by the end completely ignores that measurement as they adjust the bracket based only on it being level. The measurement and initial placements of the support legs they ask you to do are completely unnecessary. The video itself readjusts the support legs 3 times in order to install the bracket correctly. If you purchase this item I would ignore the video and only adjust the bracket so its level to your window frame. Constantly readjusting the legs is a pain especially as you have to go back and forth with tightening/loosening screws with pliers.
