Buying Guide
- Weight Capacity: Match bracket capacity to your AC unit’s weight. Heavier units (up to 300 lbs) require rugged steel brackets, while lighter units may be fine with mid-range options.
- Window Type Compatibility: Check window design (single/double-hung, slider, casement) and wall thickness (3″–15″) to ensure a proper fit. Some brackets are not compatible with vinyl or hollow metal frames.
- Installation Method: Drill-free installation is ideal for rentals, but ensure your window frame and sill can bear the load. Consider whether you prefer indoor-only installation or a bracket that requires exterior work.
- Adjustability: Look for adjustable widths (about 31.5″ to 41.7″) and leg lengths to accommodate different openings and sill depths.
- Durability & Materials: Rust-resistant steel with epoxy or protective coatings extends life in varying weather conditions.
- Compatibility with BTU Range: Align bracket with your AC’s BTU rating (commonly 5000–24000 BTU) to ensure safe distribution of weight.
