Nowadays AC systems are being built with energy ratings up to 23 SEER which make them extremely energy efficient. These systems operate with exceptional variable compressors that help maintain the optimal comfort level by turning on and off as little as often.
The key to keeping comfortable and optimal indoor temperatures lies inside the outdoor condensing unit and in the indoor variable speed blower motor. The compressor on these high efficient AC units can variably control the flow of refrigerant and airflow going through your system.
This chart helps to illustrate how temperature is maintained and how a minimal amount of energy is used to keep the temperature consistent over long periods of time. See how much more energy a basic AC system consumes!
