The product is good but the authorized people from Hyundai service centre who installed the ac were totally unprofessional.
We had to guide them where to drill the holes and how large the holes should be for the pipe fittings.
Part of one of our walls was damaged as the hole was drilled way bigger than needed to be. Punctuality is terrible if they say they will arrive at 9 in the morning expect them to arrive sometime at 3 in the afternoon.
Be prepared for an entire day to be wasted and for working people you will need to take the day off. After the installation it took me 2 weeks of chasing the service centre to get the original bill of the installation for official purposes. You might as well get someone locally to install your split unit. In fact it will cost you even cheaper than the Hyundai centre. My hyundai service was a total disappointment. With the money being paid and taxes I would expect so much better. It's time to pull up your socks and deliver on service Hyundai.
