The Whynter Eco-friendly ARC-12S ranks just behind the top-rated NewAir AC-12000E (Est. $460) in reviews of portable air conditioners designed to cool large rooms (350 square feet). On paper, the two portable air conditioners look a lot alike: Both boast the same cooling power (12,000 BTU) and are about the same size, with remote controls, energy-saving on/off timers and self-evaporation features that owners say work well (you won't have to empty buckets of condensed water). On the downside, neither one is very quiet, reviews say. Some owners say the noise isn't too bad, but others say the racket keeps them awake at night.
The main difference is that the Whynter Eco-friendly ARC-12S draws more customer complaints than the competing NewAir portable air conditioner. Although most owners are satisfied, a sizable minority says their Whynter portable A/Cs either died quickly or couldn't cool the room at all. In fact, this happened to one out of four reviewers at Amazon.com.
The Whynter Eco-friendly ARC-12S gets plenty of owner reviews at HomeDepot.com, Amazon.com, Meijer.com and Target.com. Although all of these sites post both positive and negative reviews, those at Amazon.com are the most critical.
The Whynter Eco-friendly ARC-12S is one of the top-rated portable air conditioners here, earning a rating of 4.3 out of 5 stars with more than 20 reviews posted. Only one owner rates it below 3 stars, saying it couldn't cool the room in 95-degree-plus weather. Others complain that it's noisy or that the vents only move from side to side -- you can't point them up to make the cold air rise. Still, almost 80 percent say that they would recommend it to a friend.
