In the summer heat nothing chills us out like our Kenmore air conditioner. :) It actually took us a while to figure out which unit would be best for our family. We were also worried about the cost of electricity. However, after having our new unit for a while, we are happy to say that the SLIGHT increase is well worth it! I slept like a baby the very first night we used it. No more tossing and turning from the heat. Don't suffer any longer! We are 100% satisfied with our decision to go with Kenmore.
