We’ve only been using the GE 8,000 BTU Portable Air Conditioner a day, but it’s been working wonders already. We live in an older building that doesn’t have central air, so it gets extremely hot when the temperature starts warming up. This Air Conditioner is easy to set up and use, and it cools our living room quickly. It even has a timer, so it automatically turns on (and off) at a specific time. We couldn’t be happier!
