SEER stands for Seasonal Energy Efficiency Ratio and it indicates the cooling efficiency of air conditioner and heat pump systems. Technically, the SEER rating of an AC unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. The more cooling/heating a system puts out for each unit of energy it consumes, the higher rating it will receive. The higher the unit’s SEER number, the the more energy efficient it is and the greater the energy savings. That means lower utility bills and less of an impact on the environment. For example, by upgrading from SEER 9 to SEER 13, the power consumption is reduced by 30% (equal to 1 − 9/13). It is claimed that this can result in an energy savings valued at up to $300 per year depending on the usage rate and the cost of electricity.
To look at it another way, a SEER rating is a maximum efficiency rating similar to the miles per gallon for your car. Your car might get 28 miles per gallon on the highway, but if you’re stuck in city traffic it could be lower. If your air conditioner is 21 SEER, that’s its maximum efficiency. Most modern air conditioners have a SEER that ranges from 13 to 21, although it’s important to remember the efficiency of your system can also depend on the size of your home, your current ductwork, and other variables.
