Learn About the Differences Between SEER and SEER2

Finding the most efficient HVAC products in the greater Atlanta area can allow you to enjoy cool comfort even when the mercury rises outside. SEER and SEER2 standards can provide you with the information you need to choose the right HVAC systems for your home or business in our area.

What Is SEER?

Since 1992, a minimum seasonal energy efficiency ratio (SEER) has been required for all new HVAC installations. This rating measures the overall efficiency of an AC system during the course of a typical cooling season. Higher SEER rankings indicate more efficient equipment, which could lower your utility bills while keeping things comfortable indoors in Atlanta and the surrounding communities in Georgia.

What Is SEER2?

SEER2 went into effect on January 1, 2023, and uses a different scaling system than SEER to evaluate the efficiency of HVAC systems. While both SEER and SEER2 rating systems assess the performance and energy efficiency of systems in a controlled environment, the testing conditions used for SEER2 are expected to approximate real-life operating conditions more closely.

Comparing SEER and SEER2

Both SEER and SEER2 standards can be used to evaluate air conditioning systems and heat pumps. The primary difference between the two systems is the external pressure applied during testing. SEER tests require 0.1 inches of water-column external pressure. SEER2, however, uses 0.5 inches of water-column external pressure, which causes SEER2 ratings to be somewhat lower than comparable SEER ratings for similar systems.
