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 and used it now because it is only option for non drill required air conditioner supporter. It is very sturdy but when I received it its ends were alreday chipped off of paint. It is fine because it would be installed outside and no one look at it. However it has three major defects: First of all. when you assemble, it uses bolt and nut but its size is not really fit so witout tool you cant do it. Second, the hand is too short so even it is supporter but not really wors. It is supposed to tilt around a couple of degree so the water comes out in the end of air conditioner but the handle is too short so it tiles almost like 15 degree. I felt the air conditioner sliped down from the supporter so I bought extra panel to found its hands. The last is it basically did not care about install under air conditioner. So, when you install the air conditioner there is huge gap between the air conditioner and supporter. I also needs to buy extra foam to block this gap.

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.

Product works well. If you can figure out the very vague directions. Once done is good

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.

Window air conditioner.

I was excited to get this because I thought it would work great for my purposes and save me a lot of the usual hassles with installing a new ac unit. I was sadly and totally wrong. It’s a one size fits most with a lot of assembly. Get out your toolkit, a couple people to help, and set aside a good bit of time. The instructions are unclear with not the greatest drawings. You will need someone to hold the multiple parts together while you screw and bolt them together. Some spots are so tight you need small hands and an offset screwdriver to fit in there. Some attachments you are trying to hold a nut with your fingertip as you try to get the bolt started in them. A lock washer with a standard nut would be better there than a lock nut. It’s not particularly stable even after it’s all bolted together and doesn’t hold the an ac unit that weighs less than their maximum. It doesn’t grip the window ledge and the whole thing wants to fall out of the window. Luckily we have a deck so the outside of the ac and this support frame are sitting on a stack of boards on a bench to keep it in place. Not a well thought out or constructed piece of equipment and a waste of time and money.

This was easy to install. I did have my 16 year old help me. I needed another set of hands.

The brackets are sturdy-ish, and the hardware isnt the highest grade. But what can you expect for this price? For what it is, it does the job and does it well. Although, install was a little bit confusing due to the poorly translated instructions. I mean, you shouldnt really need to rely on the assembly directions 100% because most can look at it and see whats going on. But I found myself scratching my head a few times after reading the instructions and trying to interpret what it is exactly they want me to do. To mount to the sill, I had to utilize my own hardware, because the provided hardware stripped out (big Phillips head screws for securing to sill plate) after one attempt to drive it into a pre-drilled hole. So, to sum up; -good brackets -not so good hardware -unclear instructions -reletively easy to install despite instructions -sturdy -versitile (comes with adapters to help install over larger sills) If you use your own hardware (to mount to sill only, assembly hardware is OK) then youll be happy with this product. They just need to throw in 2 different sill mounting screws that are a different type of drive (think Allen or Star bit; something less suseptable to stripping) then this will be a 100% solid kit.

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

It is a good, sturdy bracket, especially at that price. It takes a little bit of skill at assembling things to put together and was a bit more of a project than I anticipated, but I had it done and set in about half an hour.
