What does the abbreviation "SEER" stand for in HVAC terminology?

The abbreviation "SEER" stands for Seasonal Energy Efficiency Ratio. This term is crucial in the HVAC industry as it measures the efficiency of air conditioning systems over a typical cooling season. The SEER rating is calculated by taking the total cooling output (measured in British Thermal Units - BTUs) provided by the unit during the cooling season and dividing it by the total energy input (measured in watt-hours) consumed over the same period. A higher SEER rating indicates a more energy-efficient unit, which can lead to lower operating costs and reduced environmental impact.

Understanding the SEER rating helps HVAC professionals and consumers make informed decisions about air conditioning systems, comparing energy efficiency levels among different models. This information is particularly relevant for those who wish to minimize energy consumption in their homes or businesses.
