Which brand window ac is best for chennai climate in 1.5ton model?
For higher budget go with Hitachi 1.5T model, for lower budget go with Sanyo 1.5T window model. Carrier has energy saving models not sure how it works! Split AC consumes little more power (minor) than Window AC. Make sure your AC has rotary compressor rather than reciprocating compressor. Rotary compressor has less friction and tends to be more efficient when compared to reciprocating models. Good Luck!
