I work from home and my home office gets very hot due to all the computer equipment. In the summer, the office can easily reach 100-110��F, which is uncomfortable and dangerous for the computers. I originally tried a Honeywell 8,000BTU AC but it couldn't cool the room. I then used a Wynter 14,000 BTU portable AC, which did the job but was loud and ran constantly, leading to high electric bills. I replaced it with an Impecca 14,000BTU unit, which easily cools the room, is quieter, and has a better hose attachment. The remote control is the only downside as it has a dark screen. I can't speak on its longevity or energy costs yet, but I'm pleased with the purchase and got it at a great price from the Seller.

I got my second portable air conditioner two days ago and it was just as easy to install as my first one. It's working really well and I'm very happy with it. I bought my first one 2 months ago and it's been great. It cools efficiently and economically. If you're in the market for a good portable air conditioner, this is the one to get. It works like a central unit because you can set the temperature and it only comes on when needed. It cycles down to low speed with no compressor when the area has cooled off, and goes back to high speed when the compressor comes on. It's very efficient and you won't regret buying it.
