Windmill Air has surprising refreshing and outstanding customer service after the sale. 
In today world of different companies that warranty their product before you buy it then make excuses why it’s not covered after you buy it is not the case with Windmill Air. I found they stand by their air conditioner and make everything right. I will buy a Windmill Air product again. I recommend you buy their air conditioner because of the customer service, the warranty and clean cosmetic appearance, I also like the feature of blowing the cool air toward the ceiling and then it drifts down thru out the room. It’ not a typical window ac appearance that draws your attention to it, the Windmill Air does not command attention like a typical ac with a ugly open front grill design. It is also quieter than other brand air conditioner’s.
