Good morning friends today I want to share my experience to all of you about koryo 1.5 ton. I bought this air conditioner last year. It is not getting colded all. Their customer care services are so bad. Sound level is outdoor unit high. Their service support is poor. This Ac performance is very bad I am not satisfy by it. I am very disappointed with it. There is no warranty with this product. Please don’t use this type of product. Because this is very bad quality product I waste my money please you don’t waste your money.
