Understanding SEER2 Regulations: What Stay Cool Climate Control Customers Need to Know

At Stay Cool Climate Control, we believe that it’s important for our customers to understand the latest regulations and requirements for HVAC systems. One of the most significant updates in recent years is the introduction of SEER2 regulations from the Department of Energy. In this blog post, we’ll explain what SEER2 regulations are and how they affect homeowners, as well as answer some common questions related to SEER2 and energy efficiency. 

What is SEER2? 

SEER2 stands for Seasonal Energy Efficiency Ratio, Version 2. It is a rating system that measures the efficiency of HVAC systems, specifically their ability to cool air in relation to the amount of energy they consume. SEER2 is an updated version of the original SEER rating system introduced in the 1990s. 

What does SEER2 mean for Stay Cool Climate Control Customers? 

SEER2 is an important consideration for homeowners when choosing an HVAC system. A higher SEER2 rating means a more energy-efficient system, which translates to lower energy bills and a reduced carbon footprint. 


The main difference between SEER and SEER2 ratings is that SEER2 takes into account the seasonal changes in temperature and humidity that affect HVAC system performance. SEER only measures efficiency based on fixed conditions, like in a laboratory setting. SEER2 is considered an improvement over SEER because it accurately represents how well an HVAC system performs in real-world conditions. 

SEER2 Requirements

Starting in January 2023, new HVAC systems installed in the United States  must meet a minimum SEER2 rating of 14. This is an increase from the previous minimum SEER  rating of 13. 

SEER2 and Energy Savings

Upgrading to a higher SEER-rated system can save homeowners a significant amount of money on their energy bills. For example, upgrading from a SEER 10 system to a SEER 16 system can save up to 60% on cooling costs. Although higher SEER-rated systems are more expensive up front, they can provide long-term savings in energy costs. 

Tax Credits and SEER2

Homeowners who upgrade to a high SEER-rated HVAC system may be  eligible for a tax credit. The tax credit for HVAC SEER is up to $300 for qualified systems  installed from January 1, 2022, through December 31, 2023. To qualify, the system must have a  SEER rating of at least 16 and an EER rating of at least 13. 

Refrigerant Changes

R-410A, which is a commonly used refrigerant in HVAC systems, is being  phased out in the near future due to its high global warming potential. It will be replaced with a  new refrigerant called R-32, which has a lower global warming potential and is more  environmentally friendly. This change is set to take effect in 2025. 

HVAC Replacement and Cost Savings

The cheapest time of year to replace an HVAC system is  typically during the offseason, such as fall or spring. By replacing an older, less efficient system with a high SEER-rated system, homeowners can save money on their energy bills and  potentially recoup the cost of the new system within a few years. 

At Stay Cool Climate Control, we are committed to helping our customers make informed decisions about their HVAC systems. By understanding SEER2 regulations and upgrading to a high SEER-rated system, homeowners can save money on energy bills and live a happier, more comfortable life.
