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

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.

The connections once completed are solid but the side to side and depth adjustment procedure are unnecessarily burdensome and when you’re done the end of the interior braces have a vertical piece that is in the way of the air conditioner’s side panels

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.

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.

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.

The directions will tell you that the hex bolts are 3/8, and that is even stamped on the head of the bolt. BUT IT IS NOT TRUE!! Only a 10mm wrench or socket would fit them. Even worse, the screws broke during installation and I used my own spares to build. The instructions reference numbers and letters for parts and steps, like you would expect, but the instructions were poorly written. I hope they didnt use Google Translate for the instructions! I did install the product in the end but it was a rough experience and took twice as long as it should have.

The unit was difficult to assemble. One of the supports that goes against your house doesn’t hold up and slips off the house. In no way was this stable and after many attempt to “make it work” we threw this crap in the trash

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.

I use this for a small window AC unit on my molded fiberglass RV. I had to use different holes for the legs due to the rounded shell to make it level. Works great. I have no fears this will come off during use and destroy my AC unit. Once set up it is super fast and easy to install and remove. A bit pricey but worth the peace of mind.
