  • The silent effect is very goIt's worth buying.
Recently, I bought this mini split air conditioner heat pump system, which is far beyond my expectations in terms of cooling, heating, noise performance, and intelligent control. I used to use a traditional window air conditioner, and I couldn't sleep at night because of the buzzing noise. The indoor unit of this air conditioner is almost silent when it is running! Turn on the sleep mode at night, only a slight sound of wind, sleep all the way to dawn, finally bid farewell to "noise anxiety"! ... show more

Size: 12000BTU, 115V, 17 SEER2
Do Not Purchase this. I have spent over 2 hours trying to get a refund, as I only received 1 box of the 2 that should have been ordered. I was offered a full credit minus the warranty. Make it make sense.
