SEER stands for Seasonal Energy Efficiency Ratio. A SEER rating is used to measure the amount of energy that is needed to provide a specific output of cooling to your home. The higher the SEER rating, the more energy-efficient the cooling system is.
The Minimum SEER Rating Required for New Air Conditioning = 13
The Minimum SEER Rating Required for New Heat Pumps = 14
You can use the chart below as an example of how SEER rating can affect your utility bills. A SEER 16 unit, for example, is twice as efficient as a SEER 8 unit, and, therefore, costs 50% less to run.
