Our prime alternative is the Lennox XC25 for the new developments in technology that make the unit extremely environment friendly. If you happen to need a portable option, our decide is the Whynter ARC-14SH, excellent for medium-sized rooms, it may even considerably lower down the electric bill for even more savings. There are three main efficiency ratings to contemplate: EER, CEER, and SEER. Energy Efficiency Ratio (EER) measures how effectively a cooling system operates, with a rating of 12 thought-about to be a very good EER. In addition to being powerful and environment friendly, the ARC-14 additionally isn’t the eyesore that some portable AC units are, due to its sleek black design and digital controls.

A more prestigious honor is Energy Star’s Best list. One other factor to consider is CEER, or Mixed Power Effectivity Ratio. The upper the CEER, the more environment friendly a window air conditioner is. Primarily based on the units we tested, the typical window AC unit places out round 52 decibels.

Add one other one or two BTUs when you have a vaulted or high ceiling exceeding 9 feet. Climate: Air conditioning units in hotter climates run more incessantly.
