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 bought this brace because there is no easy way to drill into my window sills. Assembling the unit is very time consuming and frustrating -- there are a lot of pieces and the only way to find the right position is by trial and error. If you are off one way or the other, you have to partially disassemble the unit and try again. I put in two, and the second one was only slightly easier than the first. In the end, neither of the units are a close fit. They should stop the AC from hitting the ground if the window somehow fails to hold it, but its not exactly clamped on tight.

One of the hardest things I have put together. Instructions were not clear (noted, I received different instructions from someone else’s photo…mine was missing half the labels and had an awful description of which nuts and bolts to use). It’s definitely sturdy, but no more sturdy than a regular bracket. I don’t understand why these are more than double a good regular bracket. But I paid because I didn’t want to drill and there were zero cheaper options.

Too many precise adjustments and configurations to be done. Its not an easy setup. After all is done you then have to figure out the size and fitting of the the sidewalls of the window to have the window closed/shut from the sides of the AC machine.

Great for window a/c of any sixe.

Theres a discrepancy on the build instructions that states using a 7/16 wrench or socket this is absolutely wrong on so many levels, its metric not standard bolts as the kit I received had 10mm nuts and bolts. It was easy to assemble straight forward but at least include the proper hardware with this universal kit please, or update the instructions because it seems like corners were cut on material cost(s). Once my new ac unit arrives Ill update my review with some video and pictures of what Im commenting on. Get this you wont be disappointed its of great quality looks very nice and powder coated steel. My speculation this will last longer than the ac its going to support!

I would first like to say that my review is not base on the product itself but the inability to be able to use the product. I live in Canada and this was the perfect solution to installing my new 10,000 BTU A/C unit. I happley purchased the bracket and was excited to receive it after watching the video on how it was installed. Once I received the bracket, I started to look at the bracket and figure out how to install this in my 2 pain sliding window. I was having problems because based on the video, MY assumption was it went on the far inside lip of my window ledge but my friend who is a carpenter said that after watching the video that it goes between the 2 windows. That would make sense given where the bracket needs to sit. I miss judged based on video so I was unable to use the bracket (and the new A/C) for its intended purpose. Im not saying its a bad product but the video was perhaps miss leading. My suggestion is update the video and do a walk through in the video on how to PROPERLY install the bracket. Again, possibly because of the double windows and the gap being too small to install the bracket is the problem its difficult to rate the product itself. I suspect it IS a great product. Just not for my situation.

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 instructions are atrocious. They try to be as detailed as possible, but it gets overwhelming. The product itself works just fine and looks clean. It was definitely worth the price.

Looks sturdy enough for my air conditioner.

Pros: Its nice and really heavy duty. I can see this lasting a long time. It also has a built in level which was handy during installation. Cons: The setup 1) The paper instructions are not helpful at all. Thank god they had a setup video. 2) It is not easy to get the angle/Position of the arms correct. You have to unscrew the bolts, reposition the arms then screw it all back together again. You have to do this over and over again until you get the angle correct. Other AC Unit support brackets did not have this. You just pressed a button on the arm and it lets you reposition it.
