What is an Energy Efficiency Ratio (EER)?
Energy Efficiency ratings measure the amount of electricity required by an air conditioning unit to provide the desired cooling level in BTUs. The higher an EER, the more energy efficient a unit is. Federal law requires that all manufacturers display the EERs of each of their units on yellow tags so that consumers can easily compare the energy efficiency of the models they are considering. Friedrich models have some of the highest EERs in the industry.
