Seasonal Energy Efficiency Ratio is a way of measuring how much energy is used by a particular appliance, particularly air conditioners. The higher the SEER Rating the better, and more efficient the air conditioner.
The SEER Rating may be one of the most important considerations when purchasing an air conditioner, regardless of its type. Whether its a split air conditioner or a central air conditioner, the SEER Rating will help to indicate the overall efficiency and energy usage of an air conditioning unit.
If you are looking to buy an air conditioner and energy efficiency is your primary concern, the SEER Rating should be your baseline. Air conditioner manufacturers have generally been upping the overall SEER ratings year by year, and Energy Star continues to raise its standard.
Current models should generally be in the 21+ SEER range, in order to be eligible for Energy Star Certification. Older models can still be considered, however models in that are SEER 13 to SEER 16 are generally not as efficient as more recent air conditioners.
The benefit of high SEER rating can often be hundreds of dollars during the operation of your air conditioner. You will likely see ductless air conditioners selling for a few hundred dollars, however; the energy consumption by these units will likely exceed the initial costs savings.
So whether you are environmentally conscious or just conscious about your wallet, the higher the SEER, the higher the savings!
