Hi everyone, I buy voltas 1.5 ton window AC 2 year back and installed by supplier withing 50 minute of door step delivery, Since I live in rented house & change home 2 times in two year & uninstall & install the AC easily. From Last two year not a single problem in this product even after transporting in rented homes. In my state the electricity cost is 3.5 rupees/unit & run the AC for approximate 11 hour daily & got electricity bill of 1000 only rather. Its perfect product & good value for money.
