What does SEER stand for?

SEER stands for Seasonal Energy Efficiency Ratio. This term is used in the HVAC industry to measure the efficiency of air conditioning units and heat pumps over a typical cooling season. The SEER rating is calculated by taking the total cooling output, measured in British Thermal Units (BTUs), divided by the total electrical energy input in watt-hours during the same period.

The significance of the SEER rating lies in its ability to provide consumers with a way to compare the energy efficiency of different systems. A higher SEER rating indicates a more efficient system, which can lead to lower energy costs and reduced environmental impact. Understanding SEER is essential for making informed decisions about HVAC equipment, as it directly relates to operating costs and energy consumption over time.
