SEER stands for Seasonal Energy Efficiency Rating. Simply put, it is a scale that measures how much electricity a particular system will use to operate.
Just as in gas mileage for a car, the higher the number, the better.
As of Jan. 1st, 2015, the minimum SEER rating for systems in the Southern portion of the US is 14. (There is an exception to sell off the old 13 SEER inventory for up to 18 months.)
Some utility companies (currently CLECO and Entergy) offer rebates for high efficient units starting at 15 SEER. Call us for more details
