Onida Window 1.5 Ton AC
Compresser stoped working

I bought 2 window AC 1.5 ton from Next Store Gurgoan in 2010

One Onida 1, 5 Ton window, Comprosser stoped working in 5 months

One Whirlpool 1.5 Ton window, AC stopped working in 2 days from purchase.

Are they selling defected electronics as it cannont happen twice.
