Besides not working properly a unit could be damaged **Q: Is one piece for the inside and one piece for the outside? Is that what 2-piece means?** A: The best I can figure is the second "piece" is a roll of tape. Quite a disappointment considering we have 2 units to cover; curses on false advertisement. **Q: Window air conditioner cover small cover 5,000=10,000 btu outside wall a/c - i have 8000 btu size 28.0x26.5x17.0?** A: It should fit O K. I have a 8000 unit an the cover is a little large you just tuck in at the comers. **Q: Item is 10.98 at home depot, why its being sold 2.00 more?** A: maybe because of shipping? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality *by on Reviewed in the United States 3 July 2026* Bought the wrong ones but still keeping it might need it later on ### ⭐⭐⭐⭐⭐ R Perry *by on Reviewed in Canada 11 September 2021* It fits nice, but it doesn’t feel too sturdy. ### ⭐⭐⭐⭐⭐ 👍🏼 *by on Reviewed in Canada 30 August 2018* Fits perfectly --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/118159601-thermwell-frost-king-ac2h-outside-window-air-conditioner-cover-18](https://www.desertcart.hr/products/118159601-thermwell-frost-king-ac2h-outside-window-air-conditioner-cover-18) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-28*
