I had purchased Samsung 1 Ton Split ac . Initially it was working fine. But later on trouble started one by one.I felt the cooling of the AC reducing day by day.First it used to have great cooling effect and the whole room will be cool in 15 minutes after switching on the Ac.The warranty for Compressor alone is 5 years. Exactly at the end of 5 years, problems started with the compressor. Sometimes it would work and stop all on a sudden.Sometimes the compressor would not start. Also gas started leaking, and I had to refill the gas.Many of my friends are also having problem with Samsung Split ACs. I have spent a big amount so far for repairing. I have done regular services every year. But the performance has not been satisfactory.
