10 Best Window Air Conditioner Bracket No Screws 2025 in the United States

The Ivation Air Conditioner Support Bracket stands out due to its user-friendly, no-tools-required installation process, making it an excellent choice for those who want a hassle-free setup. It's designed to fit most single or double-hung windows, with adjustability from 24” to 38” and adapts to exterior wall thicknesses between 4” to 11”, providing great versatility.

The heavy-duty steel construction, coated with epoxy, ensures durability and can support units weighing up to 200 lbs, addressing the crucial need for stability. Rubberized feet and support legs add extra stability, both inside and outside the window, making it a secure option for your AC unit. However, some users might find the 19.25 by 17.25 inch dimensions slightly limiting, depending on their specific window setup.

This product is particularly suitable for those seeking an easy-to-install, stable, and durable AC bracket without the need for drilling or additional tools. It's important to ensure it fits your window specifications beforehand.

The JEACENT AC Window Air Conditioner Support Bracket is designed to hold up to 165 pounds, making it suitable for most medium to large window AC units. Made from sturdy alloy steel with a powder-coated finish, it offers good durability and resistance to weather. Its universal design fits window sills between 2" and 15.2" thick, accommodating a wide range of window types, though it is not compatible with sliding casement or casement windows.

Installation is straightforward and does not require exterior drilling, as it mounts indoors by securing to the window sill, simplifying setup for most users. The bracket includes a built-in bubble level to help position it correctly for stability. It transfers the AC unit's weight from the window sash to the support bracket itself, reducing stress on the window and enhancing safety. However, it does require drilling into the window sill using 2.5" screws, so it is not a completely screw-free solution despite the product category. The bracket’s adjustability mainly concerns fitting different sill thicknesses rather than having movable parts after installation.

If your window fits the specified requirements and you are comfortable with some drilling into the sill, this bracket provides a reliable and stable option that should make your AC installation easier and safer. Its lightweight design (under 3 pounds) and clear instructions add to user convenience. On the downside, for non-standard windows like sliding casement types or very narrow sills, this bracket will not work, and the need for drilling might be a drawback for renters or those seeking a no-damage setup.

The CAT SO RICH Air Conditioner Bracket is designed to support window air conditioners weighing up to 220 pounds, making it suitable for a wide range of units from 5,000 to 24,000 BTU. It fits most single or double hung windows, with an adjustable length from 34 to 42 inches and can accommodate wall thicknesses between 3 and 11 inches. This flexibility ensures compatibility with many window setups, especially brick, cement, or solid wood sills.

One of the key advantages is its no-drill installation, which eliminates the need for tools, screws, or ladders, making the setup safer and easier for users who want to avoid damaging their window frames or exterior walls. The bracket is made from durable, powder-coated steel, providing a sturdy build and long-lasting support. Additional non-slip rubber pads help prevent slipping and reduce vibration noise from the AC unit. It is important to note that the bracket is not suitable for hollow aluminum window sills.

The bracket includes a bubble level to assist in mounting, though installation may require careful adjustment to ensure proper angle and stability. Weighing about 10.5 pounds, it is fairly lightweight for handling but still robust enough for heavier units. This product offers a solid balance of strength and convenience for those needing a reliable, easy-to-install, and damage-free bracket, with the caveat to verify window sill compatibility beforehand.
