Hii guys I am subhojit and I will share my own experience on carrier ac .
Before I proceed let me tell you that I am using this ac for more than 3 years and its still working excellent .
The ac is very refined and it chills the room very fast .
No doubt carrier is in this market for years and definately they are going well .
I personally think that the facilities are quite good and it works well even without any servicing .
I would suggest everyone to go for it as because it is very must affordable and it offer great value for money .
The copper one it very good .
I preffer the copper one than the silver one as because it is more reliable and it is more durable .
If you guys are looking for an ac then go for carrier
