I bought this to replace my old Keystone air conditioner which was 17,700 BTU. It was really easy to install because it uses the same cage-type frame, so all I had to do was pull out the old one and slide this one in. One thing that I would note is that because this product offers heating, this uses a 6-30 NEMA plug instead of the 6-15 NEMA plug that these types of air conditioners normally use. I had to replace my outlet to accommodate this, but if you don't have an available 30amp breaker, this could end up being a big problem. Definitely something to consider, but the product works well and I definitely recommend it! ### ⭐⭐⭐⭐⭐ 18,000 BTU heat and air conditioner,built in wall unit. *by R***. on June 29, 2025* This is a very good air conditioner and easy to install, a very fair price and this unit also has built in heating, I would recommend this unit to anyone looking for a good quality heating and cooling system, it is so much quieter than the unit that I was using and it has a remote control which is very helpful due to where I had to install this unit. ### ⭐ Not so cool *by T***R on July 1, 2025* The plug for this unit is huge and won’t fit in a regular receptacle. We are trying to have our receptacle replaced in order to be able to use the unit --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.au/products/664031224-ksthw25b](https://www.desertcart.com.au/products/664031224-ksthw25b) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-05-10*
