FAQ

This cover is intended for indoor use on window-mounted air conditioners. It fits over the room-side front of the unit to help reduce drafts, dust, and heat loss during the off-season. To confirm fit, compare your AC’s front profile to the listed cover dimensions and shape, especially if your unit has a deep control panel or unusual front vents.
This is an indoor AC cover, designed to install on the inside-facing portion of a window air conditioner. It is used during colder months to help block indoor drafts around the front of the unit. It is not a substitute for a weatherproof exterior cover if you also want outdoor protection from rain, snow, or debris.
The Velcro side openings make it easier to slip the cover over the front of the air conditioner and adjust it around the unit for a more secure fit. This is especially useful on window units with side projections, control housings, or slightly irregular front shapes. After positioning the cover, press the Velcro closed so the cover sits snugly against the cabinet.
An indoor cover can help reduce cold drafts entering through the front grille area, limit warm indoor air escaping outside, and keep dust from collecting in the unit during storage months. It can also help reduce the chilly airflow many homeowners notice around a window AC left installed during winter.
You may benefit from one if you leave your window AC installed year-round and notice cold air coming through the front vents, higher heating loss near the window, or dust buildup inside the unit during the off-season. It is also useful if removing the air conditioner each winter is inconvenient.
Installation is usually simple and typically takes only a few minutes. In most cases, no tools are required. Just place the cover over the indoor face of the air conditioner, adjust it for alignment, and secure the Velcro sides. Before installing, make sure the unit is turned off, clean, and dry.
Yes. Clean or remove the air filter if needed, wipe dust from the front grille and controls, and make sure the unit is dry before covering it. If the window AC has visible air gaps around the frame, sealing those separately can further improve winter draft reduction, since a front cover mainly protects the room-side opening of the unit.
