What does the acronym SEER represent in relation to air conditioning?

The acronym SEER stands for Seasonal Energy Efficiency Ratio. It is a crucial measurement used in the HVAC industry to evaluate the efficiency of air conditioning systems over a typical cooling season. Specifically, SEER is calculated by dividing the total cooling output, measured in British thermal units (BTUs), by the total energy input in watt-hours used during the same period.

A higher SEER rating indicates a more efficient air conditioning unit, as it means the system produces more cooling power for each unit of energy consumed. This efficiency rating is important for consumers and professionals in the HVAC field to consider, as it can significantly impact energy costs and environmental effects over time. By understanding and recognizing SEER, HVAC technicians can help customers select systems that not only meet their cooling needs but are also cost-effective and environmentally friendly throughout their lifespan.
