This is actually there in my grandparents house.we purchased it last year. it has got 1 year warranty on product and 5 years warranty on compressor.
I can say its best features are auto climate technology, auto fan speed, auto power save mode, auto restart and extra heat exchanger. it has also got Filter clean indicator which also helps us to clean the filter. it has also got selectable fan speeds.it is doing good. I can suggest it.
