What does SEER stand for in HVAC terminology?

The term SEER stands for Seasonal Energy Efficiency Ratio, which is a crucial metric used in the HVAC industry to gauge the efficiency of air conditioners and heat pumps during the cooling season. This ratio defines the cooling output provided by the system in British thermal units (BTUs) divided by the energy consumed in watt-hours. A higher SEER rating indicates a more efficient unit, which can lead to lower energy bills and less environmental impact over time.

Understanding SEER is important for both consumers and HVAC professionals, as it helps in selecting systems that not only meet cooling demands but also optimize energy use. This metric is particularly relevant for energy efficiency programs and can influence regulatory standards for manufacturing HVAC equipment.
