What Is SEER2?

Written by Jay Elert | October 26, 2022

An outdated HVAC system can wreak havoc on your home comfort. It’s essential to stay up-to-date on changes in heating and cooling systems so you can maintain long-lasting comfort without increasing your energy bills.

One change homeowners will see starting in 2023 is the introduction of SEER2 ratings for HVAC equipment. Manufacturers are legally required to make changes to their regulation standards every few years. Read on the learn about the changes you should expect.

Beginning on Jan. 1, 2023, the industry standard for measuring HVAC system efficiency will change from SEER to SEER2. This change aims to make up for deficiencies in how SEER was previously calculated.

The U.S. Department of Energy (DOE) is responsible for setting the standards for appliance efficiency and issuing guidance on how manufacturers need to calculate system efficiency. Because SEER standards are many years old, the DOE created the SEER2 system to better align efficiency ratings with real-world operating conditions.

Why Do SEER2 Ratings Matter?

Changing to the new SEER2 system will help make homeowners’ air conditioners and heating systems more efficient. As a result, HVAC equipment won’t need to work as hard to satisfy your indoor comfort demands, resulting in lower monthly comfort costs.

It’s crucial for homeowners to stay on top of SEER rating changes because failure to upgrade to a new system under updated guidance could have serious consequences.

For example, when the Department of Energy raised the minimum SEER from 10 to 13 in 2006, homeowners who had just installed systems with a SEER 10 rating struggled with buyer’s remorse. Knowing when the DOE plans to update their energy-efficiency guidance can help homeowners avoid making a bad HVAC investment.

How Have SEER2 Ratings Changed HVAC Requirements for Madison Area Homes?

In 2015, three categories were established to help each state understand how updates in energy efficiency regulations will impact HVAC requirements for their customers.

Wisconsin belongs to the north region. As such, these changes will apply starting in 2023:

  • The new recommended SEER rating for air conditioning systems will increase from 13 SEER to 14 SEER.
  • Heating efficiency for air-source heat pumps will increase from 8.2 HSPF to 8.8 HSPF.
  • Furnace ratings of 81% AFUE are required in all regions.
