Buying Guide
- What window type do you have? Single or double hung windows with solid frames are best for drill-free brackets; hollow or vinyl frames may limit compatibility.
- What is your AC unit’s weight and BTU rating? Choose a bracket with at least equal or higher weight capacity and BTU compatibility (most brackets here cover 5,000–24,000 BTU).
- Does installation require tools? If you prefer no drilling, prioritize brackets explicitly marketed as drill-free or “no drill.”
- Is there a risk to the window sill or exterior frame? Look for designs that transfer stress away from the sill and sash to the window frame or wall.
- What is the mounting width range? Ensure your window opening width falls within the bracket’s adjustable range (often 31.5″–41.7″).
- Material and weather resistance: Epoxy-coated steel or stainless steel helps resist rust, especially for outdoor exposure.
