Carrier, for example, makes a large variety of air conditioners with wildly varying EERs from 8.6 to 10 below the ratings of the models in Fast Answers. Because of this conflict, we chose not to include Carrier units in ConsumerSearch Fast Answers. Rather than individual units, we gave preference in Fast Answers to product lines whose performance was consistent across the board, but if you specifically need a 5,600 Btu window unit, this Kenmore model is a bargain. By estimating the number of years you'll use the unit, you can gauge whether a higher initial cost will eventually pay off. Also thanks to government regulation, manufacturers are required to clearly display EER ratings on air conditioner units, making it easier to comparison shop.
