When shopping for nearly any electronic these days, you’ll find some kind of information about its energy efficiency as you compare products. Washing machines, TVs, and even landlines and fax machines may all carry the ENERGY STAR label, which shows that a system has met the energy requirements set forth by the EPA.
Air conditioners can also earn the ENERGY STAR label, but this only means that the system has met the minimum requirements to be considered “energy efficient.” If you live in Florida, you need more than the bare minimum. That’s why it’s so useful to look at the SEER.
