Compatibility & Fitment
- Universally compatible with most standard window-mounted air conditioning units measuring up to 21" W x 15" H x 3.5" D.
- Fits major appliance brands including General Electric (GE), Frigidaire, LG, Haier, and Kenmore, provided the physical dimensions match.
- Designed strictly for indoor use; not intended to protect the exterior condenser unit from outdoor weather elements.
When to Replace
- Transitioning into the fall and winter seasons when the window air conditioner will remain installed but powered off.
- Noticeable cold air drafts or wind noise can be felt entering the room through the AC vents.
- The existing winter cover has torn seams, degraded elastic edging, or failing hook-and-loop fasteners.
- The internal polyester insulation has compacted or flattened, losing its thermal sealing properties.
Installation Tips
- Turn off and unplug the air conditioning unit from the wall outlet before installing the cover for the winter season.
- Wipe down the front plastic grill of the AC unit with a dry cloth to ensure no dust or moisture is trapped beneath the fabric.
- Slip the cover over the top corners of the unit first, then pull the elastic edges down evenly over the bottom corners.
- Secure the side hook-and-loop straps firmly against the unit casing, ensuring the power cord is safely routed through the side gap without being pinched.
