Buying Guide
- Window type compatibility: Most brackets target single- or double-hung windows. Verify that your window type (and opening width) matches the bracket’s adjustable range before purchasing.
- Wall material and frame: Brackets rely on solid walls (concrete, brick, stone, wood). Hollow or vinyl frames may not offer secure support; confirm material limitations in product notes.
- Weight capacity: Choose a bracket rated for at least the BTU rating of your AC unit plus some margin. Heavier units require sturdier, wider brackets with robust mounting points.
- Drilling and installation: If you cannot drill, prioritize drill-free models designed for interior setup. Consider the installation effort and whether exterior work is acceptable in your building.
- Stability features: Look for non-slip pads, weight distribution design, and rubberized feet to reduce movement, vibration, and window sill wear.
- Adjustability: Wider adjustable width and leg-length ranges improve compatibility with a broader range of window openings and wall thicknesses.
