This is probably a rare defect product from samsung.
I am using this AC for 3 months and I am facing some problems which I am pointing out below.
First of all when temperature crosses 38 degree the AC stops cooling throwing away only compression wind. Changing the stabilizer also didn't work.
Second, the AC makes a vibrator type sound when you keep the AC in swinging mode.Above 25k 1 ton ac according to me not worth it and totally waste of money.Only a good point to be pointed out is samsung services which is unquestionable everytimeI wont recommend at all.
