SEER to SEER2: What to Know About the New AC Efficiency Rating


As an HVAC contractor with years of experience serving homeowners with AC installation and AC repair in Shreveport and the surrounding areas, we’re dedicated to keeping our customers informed about the latest advancements in the industry. One such advancement that every homeowner should be aware of is the transition from the older Seasonal Energy Efficiency Ratio (SEER) rating to the newer SEER2 rating for air conditioning systems.

Understanding the Difference: SEER vs. SEER2

In the past, the SEER rating was the standard metric used to measure the energy efficiency of air conditioners. However, with advancements in technology and a growing focus on sustainability, the industry has evolved, leading to the introduction of the SEER2 rating.

The primary difference between SEER and SEER2 lies in how efficiency is calculated. While SEER provided a good benchmark for comparing the efficiency of different AC models, SEER2 takes into account a broader range of factors, including variable-speed operation and part-load performance. This means that a SEER2-rated system may have a lower numerical rating than an older SEER-rated system while still providing superior energy efficiency and performance.

What Homeowners Should Look for in SEER2-rated Systems

For homeowners considering the installation of a new air conditioning system, it’s important to understand what to look for in SEER2 ratings. While a higher SEER2 rating typically indicates greater energy efficiency, it’s not the only factor to consider. Other features, such as variable-speed compressors and advanced humidity control, can significantly impact a system’s overall performance and energy savings.

When choosing a SEER2-rated system, homeowners should also consider factors such as the size of their home, climate conditions, and budget constraints. A system with a higher SEER2 rating may require a larger upfront investment, but it can lead to significant long-term savings on energy bills.

The Importance of Professional Advice and Installation

While it’s tempting for homeowners to research AC systems online and attempt to make a decision based solely on numerical ratings, the truth is that selecting the right system requires expert guidance. HVAC professionals like ours have the knowledge and experience to assess a home’s specific needs and recommend the most suitable system. 

In addition to helping homeowners choose the right system, professional installation is essential for ensuring optimal performance and efficiency. A poor selection and installation of an AC will mean it will waste energy—no matter how energy-efficient its SEER2 rating says it is. It will also suffer more malfunctions and have a shorter service life. By investing in professional installation, you can enjoy peace of mind knowing that your new AC system will operate reliably and efficiently for years to come.
