O GENERAL IS THE BEST AIR-CONDITIONER;
CARRIER AIR-CONDITIONER ALSO THE BEST AIR-CONDITIONER.
I TRIED CARRIER AIR-CONDITIONER IN MY HOUSE AND FOUND IT TO BE VERY GOOD.
O GENERAL AIR-CONDITIONER PEOPLE SAY THAT IT IS THE BEST BUT I HAVE NOT TRIED BUT HAVE SEEN IN ONE SHOP. IT IS AS GOOD AS CARRIER AIRCONDITIONER.
Always, consult a good experienced air-conditioner engineer so that you get the best airconditioner for your house or office.
