[Resolved]  Viveks India — ac coil mismatch

I have purchased 2 voltas split ac1.5 ton model vertis premium 3s at vivek showroom vadapalani on may 2010, recently i have shifted my home and raise for instalation in voltas, ac technician told one ac is copper coil and another is aluminum because of that gas is leaking, now only we came to know that difference in coil but we paid same price for both ac, replace coppercoil and do the needful at earliest
