Everything You Need to Know About SEER2 Requirements

what are SEER2 regulations

Starting in January, SEER2 regulations go into effect. What are SEER2 regulations? We’re so glad you asked. Here’s everything you need to know.

What is SEER?

SEER, or Seasonal Energy Efficiency Rating, is the rating given by the United States Department of Energy to air conditioning and heat pump units. The rating shows how much energy they use in one year. They calculate it by dividing the cooling output by the energy input. The higher the rating, the more energy efficient the unit is.


SEER2 is like SEER in that it’s still an energy efficiency rating, but it’s updated to account for real-world conditions. In technical terms, it means that the calculation for testing has an increased external static pressure requirement. That means higher efficiency ratings will be the requirement for all newly manufactured equipment, and equipment sold starting on January 1, 2023.

SEER2 and Your HVAC Equipment

SEER2 regulations apply to manufacturers and sellers of HVAC equipment, but for homeowners, it’s an opportunity to ensure your system is up to date and as energy efficient as possible. The new minimum SEER2 rating is 14.3, which means that even the HVAC equipment with the lowest permittable efficiency is still more efficient than the more efficient systems sold in 2022.

SEER and SEER2 regulations and requirements are confusing and can affect the cost of HVAC equipment not and into the new year. So instead of playing the guessing game, turn to the heating and air conditioning pros for the guidance you need.
