SEER
Seasonal Energy Efficiency Ratio (SEER) measures how efficiently an air conditioning system or heat pump cools over an entire cooling season. It is calculated by dividing the total cooling output (in BTUs) over the season by the total energy consumed (in watt-hours). A higher SEER rating means the system is more energy-efficient, resulting in lower energy costs for the same amount of cooling. Modern HVAC systems typically have a SEER rating that ranges from 13 to 25, depending on the model and efficiency standards.
