What does SEER stand for in relation to air conditioning units?

SEER stands for Seasonal Energy Efficiency Ratio, which is a critical measurement used to assess the efficiency of air conditioning units. This term is significant in the HVAC industry because it compares the total cooling output of an air conditioner during a typical cooling season to the total electrical energy input in watt-hours. A higher SEER rating indicates a more efficient air conditioning unit, meaning it uses less electricity to produce the same amount of cooling compared to units with a lower SEER.

Understanding SEER is essential for both consumers who are looking to purchase a new air conditioning system and professionals in the HVAC field, as it ultimately helps inform decisions related to energy consumption, operational costs, and environmental impact.
