What are SEER and EER?
Seasonal Energy Efficiency Ratio (SEER) is the measure of a unit’s average energy efficiency over a cooling season.
The federal energy-efficiency standard for new equipment changed in January of 2006 from 10.0 SEER to 13.0 SEER. Units manufactured after January 23, 2006 must have a SEER rating of 13.0 or higher. While 13.0 SEER equipment may be more efficient than your current system, it is now considered standard efficiency.
System Components Must Match
There are two types of systems; package units that contain their components in a single enclosure, and split systems that have an outdoor condensing unit and an indoor coil. If you choose a split system, the condensing unit and the coil components must be matched and replaced together when a new system is installed to ensure that your new cooling equipment performs at its peak efficiency.
