Can you suggest a good split-type airconditioning unit?

Inverters are a good kind of split-type airconditioning unit. A lot of brands carry that kind like Samsung, Carrier, Condura etc. While it may cost you a lot in buying one unit, with an additional for installation, you can save more in the long-run because of its electricity consumption. Usually, choosing an aircon must be based on the size of your area.

I've heard a lot of good reviews about Samsung split-type airconditioning unit. Yes, pricey it is! However, it has lower kilowatts which means lower electricity consumption as compared to the usual types of airconditioning units.
