When considering an HVAC system for your home or business, energy efficiency and environmental impact are more important than ever. EER, or Energy Efficiency Ratio, serves as a key metric in evaluating the cooling efficiency of air conditioning units. Systems with higher EER ratings typically consume less energy to produce the same cooling effect, translating to lower utility bills and a reduced carbon footprint. When shopping for HVAC units, paying close attention to the EER can help ensure you select a model that meets your comfort needs while remaining cost-effective and environmentally responsible over its lifespan.
EER = 0.875 × SEEREER = BTUOUTPUT / WATTSINPUT
EER = Output Cooling in BTU per hr / Input Energy in watts per hr

EER = Energy Efficiency Ratio
SEER = Seasonal Energy Efficiency Ratio
* = Multiply
/ = Divide
+ = Add
– = Substract
√ = Square Root
