Seems like the quality of Samsung ACs are deteriorating by the day. I have owned 3 Samsung acs and all of them have progressively failed within 5 years. The 1st one lasted for 5 years, the second for 4 years and the 3rd for less than 2 years and already has a leaking cooling coil. Even after the cooling cool was replacedtgere seems to be issues.
The initial cooling is good and as long as it works well you are happy. Once it has troubles, it’s just time to throw it away.
It is better to spend another 10k and buy a better built ac rather than going for this product.
