Buying Guide
Key considerations when choosing a universal window AC bracket:
- Weight capacity: Match the bracket to your unit’s weight and any added accessories. Heavier units require sturdier brackets (200–300 lbs range).
- Window type compatibility: Ensure your window style (single/double-hung, sash thickness, sill height) fits the bracket’s expansion and legs.
- Installation method: No-drill vs. light-drill options. No-drill generally preserves window integrity but confirm if exterior work is entirely avoided.
- Wall thickness and BTU range: Check maximum wall thickness the bracket supports and whether it accommodates your unit’s BTU rating (5,000–24,000 BTU commonly supported).
- Rust and durability: Look for epoxy-coated or stainless steel builds for long-term weather resistance, especially in exposed installs.
- Clearance and fit: Ensure the bracket does not obstruct vents or window operation and that it aligns level on both sides for stability.
