Question

Accepted Answer

An air conditioner’s Seasonal Energy Efficiency Ratio (SEER2) measures its average cooling efficiency over the entire cooling season, over a range of temperatures from 65°F to 104°F. A unit’s Energy Efficiency Ratio (EER2) measures its cooling efficiency at peak cooling need, when the temperature is 95°F. Replacing an old central AC unit with a low SEER2 rating with a new, energy-efficient AC unit will help save energy and save money on your cooling bills. An AC unit uses the most power when it cycles on. So, a single-stage air conditioner, or even a two-stage AC unit, can use a lot of power as they turn on and off more frequently. Contrast that with a multi-speed system or a premium variable-speed system. They run for a longer time at lower speeds, using the minimum amount of energy to provide enhanced comfort. While a single-stage unit runs at 100% capacity whenever it’s on, our variable-speed units can run at 30-100% capacity, depending on your set temperature and the temperature outside. Higher SEER2 and EER2 ratings go hand-in-hand with multi-speed and variable-speed air conditioning systems.
