my central air in my house right now I am bored with I am in California in the high desert the hardest part of setting this up was getting it out of the box LOL everything was there screwing the pieces into the exhaust hose is a bit tricky but I actually wake up at night because I have it in the bedroom and Im cold this is an awesome awesome unit. Just have to remember its not to use in the whole House by my bedroom and a huge bathroom and three dogs and we all sleep really comfortable it is not any louder than a small fan on low is awesome. You cant beat the price sounds expensive for one room but Best one out there so far I will not buy any other units then this one for other rooms in my house￼￼￼￼￼￼
