Great ice cold air

[This review was collected as part of a promotion.] This air conditioner is great! It was very easy installation. Everything needed to install came in the box. We have central air but our son's room always stays hot, so we added this to his room, and it made such a big difference! Low level noise, energy efficiency, plus dehumidifier all wrapped up in one with a remote control added on top of it all! Great product

Smoothly, quietly bringing cool air

[This review was collected as part of a promotion.] The unit works like charm. My master bed is hotter than the rest of the rooms in the house. This AC definitely helped cool down my 470 square feet room quickly. It runs smoothly and quietly during the operation. It came with everything you need to install. It has a remote control and comes with batteries as well. It is the first time my husband set it up. It took him about 30 minutes to finish the job.
