Our prime choice is the Lennox XC25 for the brand new developments in know-how that make the unit extraordinarily efficient. When you need a portable option, our pick is the Whynter ARC-14SH, excellent for medium-sized rooms, エアコン取外し 鹿児島 it may even considerably cut down the electric bill for even more savings. There are three major effectivity ratings to contemplate: EER, CEER, and SEER. Energy Efficiency Ratio (EER) measures how successfully a cooling system operates, with a ranking of 12 considered to be a great EER. Along with being highly effective and environment friendly, the ARC-14 additionally isn’t the eyesore that some portable AC units are, because of its sleek black design and digital controls.
