What does EER stand for in HVAC systems?

In HVAC systems, EER stands for Energy Efficiency Ratio. This metric is crucial as it measures the efficiency of cooling devices, such as air conditioners, by comparing the cooling output (measured in British Thermal Units, or BTUs) to the electrical energy input (measured in watts) over the same period. A higher EER indicates that the unit is more efficient, providing more cooling for the amount of energy it consumes.

Understanding EER is essential when selecting HVAC equipment, as higher energy efficiency ratios can lead to significant energy savings and reduced utility bills for consumers. The concept helps both homeowners and contractors make informed decisions about energy consumption and efficiency when choosing air conditioning systems, ultimately contributing to greener and more sustainable practices in the HVAC industry.
