What does the term "SEER" stand for in relation to heat pumps?

The term "SEER" stands for Seasonal Energy Efficiency Ratio. This measurement is crucial in evaluating the efficiency of heat pumps and air conditioning systems. The SEER indicates the cooling output provided by the system during a typical cooling season, divided by the total energy consumed in watt-hours over the same period. A higher SEER rating means a more efficient system, which can lead to lower energy bills and reduced environmental impact.

Understanding this metric is fundamental when selecting a heat pump, as it helps homeowners and professionals alike determine the potential energy savings and performance of a unit over an entire season rather than a singular point in time. This is particularly important given the varying demands and environmental conditions that affect heat pump operation throughout the year. It emphasizes the system's efficiency on a seasonal basis, which is more indicative of real-world performance compared to a singular efficiency metric.
