All This Talk About SEER Rating, Just What Is It?

Posted on

Being in the Heating and Cooling industry one of the questions we receive a lot is, what is a good SEER rating?

 

If you are unfamiliar with SEER, it is the Air Conditioning Industries way for rating the efficiency of their units.  It stands for Seasonal Energy Efficiency Ratio.  A SEER rating is the ratio of the cooling output of an air conditioner over a typical cooling season, divided by the energy it consumed in Watt-Hours.

 

In the state of Kentucky, all new residential HVAC systems must have a minimum rating of 14 SEER.  HVAC systems with an Energy Star rating must have a SEER rating of at least 15 SEER.

 

The higher the SEER rating of the system, the more energy efficient it is.  For instance, a 10 SEER unit is far less efficient than an 18 SEER unit, a whopping 44% less to be exact.  So to answer the question, the higher SEER the unit, the better results you will see.  You may spend a little more on purchasing a higher SEER system, but will save money on energy expenses for years to come.
