The Seasonal Energy Efficiency Ratio (SEER) measures how efficiently a unit cools by comparing its cooling output with the amount of electricity it uses in a typical cooling season. In simpler terms, SEER represents the amount of energy and money needed for the unit to run efficiently throughout a whole year. The energy efficiency of a unit increases as its SEER rating increases.

The SEER rating is calculated by dividing the cooling output of a system over a cooling season by the total energy used in watt-hours. The SEER ratio obtained by the calculation represents the maximum efficiency of a unit.

For example, air conditioning units manufactured a decade or so ago usually possess a SEER rating ranging from 8 to 10.

Identify Seasonal Energy Efficiency Rating

You can usually find the Seasonal Energy Efficiency Ratio (SEER) rating of your current unit through one of the following methods:

  • Take a look at the vibrant yellow and black EnergyGuide sticker on the exterior unit.
  • On a piece of paper that is attached to the indoor or air handler of the HVAC system.
  • The SEER rating is commonly indicated by the model number of the product. A model number such as XV20i corresponds to a remarkable 20 SEER efficiency rating.
  • Locate the model and serial number of the unit and reach out to the manufacturer for the SEER.

Seasonal Energy Efficiency Ratio 2

SEER2 incorporates the latest M1 blower testing procedure to provide an enhanced and up-to-date calculation. So, SEER2 or Seasonal Energy Efficiency Ratio 2 represents the new standard.

This rating deals with the total amount of heat removed during the annual cooling season from the place where the HVAC system is installed. The latest M1 testing procedure magnifies the external static pressure of the systems by five times. This is done to more accurately simulate the real-world conditions of installed equipment.
