In HVAC systems, what does SEER represent?

SEER stands for Seasonal Energy Efficiency Ratio, which is a critical measurement used to evaluate the efficiency of air conditioning systems and heat pumps. It represents the total cooling output provided during a typical cooling season, divided by the total electric energy input consumed during that same period. The higher the SEER rating, the more energy efficient the system is. This rating helps consumers compare the efficiency of different HVAC systems, promoting the selection of units that will result in lower energy costs over time. Understanding SEER is essential for making informed decisions related to energy efficiency in HVAC systems, which is a key focus in the field of building performance and energy efficiency.
