The gaps around your window AC are costing you money. BreezeStop seals them.

The accordion plastic panels your unit came with aren't real insulation — they flex in wind and let cold air straight through. BreezeStop fits directly over them, sealing every gap and giving the whole installation a clean, finished look.

What's in the box:

  • 2 side panels (18"×10") — slip over your existing accordion sides
  • 1 top panel (36"×1.75") — seals the gap above the unit most people ignore
  • Adhesive flaps — attach to the unit, not your wall or window frame

What it does:

  • Stops cold drafts in winter
  • Blocks hot air infiltration in summer
  • Reduces outside noise
  • Turns an eyesore into a clean, built-in look

What it takes to install:

  • Scissors or a utility knife to trim to fit
  • No tools, no hardware, no contractor

Works with: Any window AC brand. Fits windows up to 36" wide.

Before you buy

Questions, answered

Will it fit my AC unit?
It fits any traditional window AC in a window up to 36" wide. The panels are trimmed to size during install, so you get an exact fit. Wider window? There's a large size available too.
Does the adhesive damage my wall or window?
No. The adhesive flaps attach to the AC unit itself - not your wall, trim, or window frame. Nothing sticky touches your home, and the panels peel off cleanly.
Do I need tools to install it?
Just scissors or a utility knife to trim the panels to fit. No drilling, no hardware, no contractor. Most people are done in a few minutes.
Can I take it off and reuse it?
Yes. It's removable and reusable, so you can take it down when you pull the unit for the season and put it back up next year.
What exactly comes in the kit?
Two side panels (18"x10"), one top panel (36"x1.75"), and pre-attached adhesive flaps. Everything you need to seal a standard window AC.
