What is SEER?
SEER is a simple mathematic equation that divides the output of your air conditioning unit during the cooling season (measured in BTUs) by the amount of energy it consumes during that same time period (measured in watt-hours). The higher the SEER rating of a given air conditioner, the less energy it will need to cool your home effectively.
What is a Good SEER Rating?
The current SEER minimum rating available for purchase (of newly modeled manufactured air conditioners) is 13. This minimum has been in place since January 2006, whic replaced the prior minimum rate of 10. If your home has an older air conditioning model and is below a rating of 13, it is considered a low efficiency rating and depending on your monthly electricity charges in the summer, it may be a good idea to look into what a higher SEER could do for you in the long run.
