An air conditioner draws heat energy out of the house and transfers it to the outside air.

The most common setup for residential homes is a split system, which includes an inside-the-home evaporative heat exchanger and an outside condensing unit heat exchanger.

The performance of vapor compression refrigeration cycles is limited by thermodynamics, making it difficult to achieve high thermal efficiencies.

The Coefficient of performance (COP) measures performance, but it's not a widely adopted measure. Instead, the Energy Efficiency Ratio (EER) has traditionally been used to characterize the performance of many HVAC systems.

The EER is based on a 35 °C (95 °F) outdoor temperature, which may not accurately reflect real-world performance.

The Seasonal Energy Efficiency Ratio (SEER) is a more accurate measure of performance, based on seasonal temperature averages instead of a constant outdoor temperature.

The current industry minimum SEER rating is 14 SEER.

The fan blades used to move the air in HVAC systems are often stamped from sheet metal, but this can make them less aerodynamically efficient.

A well-designed blade could reduce the electrical power required to move the air by a third.
