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

Sturdiness of brace without using screws or nails!

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.

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.

At the end of the day, this have proven to be the solid support that I sought. The description on Amazon is at best confusing if not inaccurate. I bought the “medium duty” dual-armed bracket for a 12,000 BTU LG air conditioner. The box says it is “light duty” and, in one place, says: “supports up to 80 lbs., typical range 5,000-10,000 BTU,” but the label on the box says: “to 12,000 BTU.” It is very sturdy and easily supported by 85-pound unit (installed correctly). The installation instructions are incomplete and poor, but since I have previously installed two single-arm support brackets from another manufacturer (with better instructions), I had little problem. The biggest error/omission in the instructions is the failure to adequately address the need to level the horizontal arm by adjusting the point on the horizontal arm where one attaches the angled bracket (that presses against the exterior wall). (The instructions seem to presume that the attachment point is at the far end of the horizontal arm, in conjunction with bolting on the bracket that connects the two horizontal arms, but this is WRONG for any but the very thickest house wall. This explains why some comments talk about “hanging” angled arms—they were simply installed incorrectly, probably because of the inadequate instructions.) For most wall thicknesses, the angled bracket must be attached several holes before the end, and this point of attachment may have to be adjusted several times as one trial-fits the air conditioner so that the horizontal arm leans slightly down so that condensate flows out rather that in. This problem is compounded by that fact that an insufficient bolts are provided for the connecting bracket if one attaches the angled arm at some other point on the horizontal arm. The screws supplied stand up perfectly well if one uses a correctly sized Phillips head screw driver.

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

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.

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 dust If you dont 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. Ive 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 didnt 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 Im very pleased with the product.

The hardware seems quite sturdy. With the two support beams it is a lot more stable than the single support beams most similar air conditioner brackets have. I haven’t used it long enough to know how it will hold up. The installation instructions are definitely lacking. There are parts included that are not in the instructions. There are numbers pointing to parts in the diagrams that are not in the list of parts that should show what the parts are that the diagram points to. Sections of the instructions I never did figure out. Then some definite errors. Instructions said to use a 7/16 inch socket. That is too big, use a 10 mm socket instead. Instructions said use a 5/32 inch drill bit. Too small, even in soft wood trying to put the screw in started to strip the head almost immediately. 3/16 inch drill bit works much better.

This Alpine A/C support bracket is well designed and well made. It is held together with bolts and screws, which make this adjustable bracket very sturdy. I ordered this bracket, because I had to return an Ivation bracket that was very poorly welded together and used cheap spring pins for adjustments.

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.
