The energy efficiency ratings of central air conditioner systems have changed as of 2023. Until the last day of 2022, the HVAC industry used the Seasonal Energy Efficiency Ratio (SEER) rating to determine air conditioner efficiency ratings. However, this old rating has already been replaced by the SEER2 rating as of January 1, 2023. 

Here, we discuss the SEER2 rating changes and how they are relevant to homeowners in the Southeast region, so you’re well-informed. 

What are the Recent Changes to the SEER2 Ratings? 

SEER was the primary energy efficiency rating for central air conditioner systems prior to 2023. It determined the energy efficiency of AC units by taking the weighted average of the unit’s input wattage at varying cooling outputs. The SEER rating is calculated by dividing the annual cooling output by the cooling season’s total electric energy output. 

The US Department of Energy introduced the SEER2 rating in 2023, which uses the same calculation but is tested under different conditions. 

What’s the Difference Between SEER and SEER2? 

SEER and SEER2 are essentially the same in most aspects, except the measurement for SEER2 ratings includes harsher test conditions in relation to the AC unit’s external static pressure. The difference might seem minimal, but it’s presumed to impact air conditioning energy efficiency ratings significantly. 

With the introduction of the SEER2 rating, the HVAC community is gradually adjusting to the following main changes that affect the SEER rating: 
 

● The minimum SEER rating in Southeast and Southwest states increased from 14 SEER to 15 SEER
● The SEER rating is getting replaced by the SEER2 rating, which is 4.5% lower than the previous rating 

So, what does this entail for the energy efficiency rating of AC units and heat pumps? 

According to the US Department of Energy’s Energy Conservation Program, the total consumer costs and savings for central HVAC systems range from $2.5 billion to $12.2 billion . This is the projected economic effect of the higher minimum SEER rating and the new SEER rating for the 30-year period that starts in 2023 and ends in 2052. 

What Does This Mean For Energy Efficiency? 

The US Department of Energy raised the minimum energy efficiency requirements for central HVAC systems in an effort to help consumers choose systems that effectively keep indoor spaces cool while lowering energy usage and monthly utility costs. 

It’s worth noting that the greater efficiency of new AC units might result in a price increase. However, the returns are much greater than the initial investment cost. It’s also worth noting that it may be more challenging to find replacement parts for older HVAC systems that don’t have the SEER2 rating as the standard.

How Will the SEER2 Ratings Changes Affect You? 

The transition from SEER to SEER2 ratings will result in various changes regarding energy consumption, utility costs, repair and replacement part availability, and so much more. For this reason, it’s essential to understand the rating changes and how they affect the industry — helping you make informed decisions about your HVAC unit. 

The new SEER2 ratings indicate that it’s time to invest in a new, more energy-efficient central HVAC unit. In fact, all central air conditioning and heat pump symptoms must already adhere to current SEER2 settings — systems that meet the SEER standards pre-2023 need to be scheduled for renovation and regulation. 

In addition to meeting industry requirements and lowering energy consumption and utility bills, a unit upgrade can improve indoor air quality. An HVAC unit that uses the latest technology and adheres to the current industry standards also reduces the risk of avoidable unit breakdowns and expensive air conditioning repair services. 

As the SEER2 ratings work toward higher energy efficiency, it’s time for your residential HVAC system to do the same. Install a new unit to avoid costly energy bills and repairs. Pair it with a preventive care program to get the most out of your system for longer.
