We live in an older mobile home on our property  and planning on building soon so when the AC stopped working we decided to try this window unit. We didn’t want to pay for a new AC and with Covid I was now working from home. This has kept us cool and has lowered our electric bill. We installed it July 2020 and haven’t had any issues. It even made it through hurricane Sally and kept us cool while the power was out and it was plugged into a generator.
