Sizing Up Your Air Conditioner
Be sure to choose the right size air conditioner for the best performance. There are many factors involved in picking the right air conditioner, but when it comes to the size, bigger is not always better. Factors such as shade, your building size, insulation, air leaks and heating capacity should be questioned.
Air Conditioning Efficiency
National minimum standards for central air conditioners require a SEER of 9.7 and 10.0, for single-package and split-systems. However, you do not need to settle for the minimum standard, as there is a wide selection of units with SEERs reaching nearly 17.
