If you've got a 5000 BTU window AC unit, these Powrocket side panels are a game-changer. I installed them on my Mainstays AC, and the fit was perfect—no gaps, no fuss.

The insulation is impressive. Before these panels, I could feel cool air escaping around the edges of my AC. Now? My room stays noticeably cooler without the unit working overtime. That’s energy savings right there!

Installation took me less than 10 minutes. The frames are sturdy but lightweight, and the accordion-style curtains adjust smoothly to fill any uneven gaps. No more drafts sneaking in!

One minor gripe: Double-check your AC’s dimensions before buying. While they fit most 5000 BTU models (like my Mainstays), sizing quirks can happen. But once confirmed, it’s smooth sailing.

For under $20, this kit solves a real problem—keeping cool air IN and hot air OUT. Highly recommend for anyone tired of battling inefficient cooling.
