- Safety features: Consider dual-arm designs, anti-slip feet, and weight transfer to window frames to minimize stress on sills.
- Compatibility with BTU range: Ensure the bracket’s capacity aligns with unit size and future upgrades.
- Ease of adjustment: Some models offer adjustable widths or leg distances for precise fit, which helps during leveling.
- Maintenance and warranty: Check for manufacturer guarantees and availability of replacement parts or accessories.
