New DOE Energy Efficiency Ratings for Residential Split A/C Systems in 2023…So What?

New DOE Energy Efficiency Ratings

On January 1, 2023, the U.S. Department of Energy’s (DOE) new minimum efficiency standards for residential split A/C systems went into effect.  These new regulations are part of the DOE’s ongoing initiative to reduce overall energy consumption in the United States.  Additionally, the DOE test procedures have evolved to be more representative of real-world installations in today’s residences and will now be used to rate the level of energy efficiency.

For decades, the HVAC industry has used the term “Seer” to reflect the energy efficiency rating of an A/C system.  Moving forward, the new term will be “Seer2”.

As we all can imagine, there are countless details we can get immersed in when reviewing DOE standards and A/C technologies.  The purpose here is to provide a high-level summary of the main impact that Seer2 ratings will have on us as consumers in the South Florida marketplace.


What key changes does the Seer2 rating bring to the table?

As it relates to the Seer2 initiative, there are 3 U.S. Regions – North, Southeast, and Southwest.  Obviously, South Florida, Boca Raton and Delray Air Conditioning Companies are part of the Southeast Region.  The DOE’s stated objective in the Southeast was to drive a 7-10% energy efficiency increase with residential split A/C systems.

With the “classic” Seer ratings that were in place before 2023, there was a minimum Seer level requirement of 14.0 Seer for all split A/C residential systems.  Using the same pre-2023 “classic” Seer rating, the new baseline requirement starting in 2023 is 15.0 Seer.  The conversion of Seer level to new Seer2 level is 15.0 to 14.3.  Stated otherwise, 15.0 Seer equals 14.3 Seer2.

An additional consideration for the new Seer2 rating requirements is the fact that they are dependent on the size of the A/C system.  For a residential split A/C system of size smaller than 4 tons, the minimum Seer2 requirement is 14.3.  For a residential split A/C system of size 4 tons or larger, the minimum Seer2 rating requirement is 13.8.

FPL offers a $150 Rebate towards the purchase of a new A/C System, what is the minimum Seer2 requirement?

FPL requires a Seer2 rating of 15.2 to qualify for their energy efficiency Rebate Program.  The 15.2 Seer2 requirement applies to systems of all sizes in order to qualify for the FPL Rebate.

Understanding Efficiency Standards

Efficiency standards play an equivalent crucial role in promoting energy conservation and reducing environmental impact. In 2023, new equivalent minimum energy efficiency standards will be implemented for residential split air conditioning (A/C) systems. These updated requirements, equivalent for both manufacturers and consumers alike, will have significant implications.

2023 Requirements

The upcoming changes in energy efficiency standards will require higher Seasonal Energy Efficiency Ratio (SEER) ratings for split A/C systems. SEER is a measurement that indicates the cooling output of an A/C unit over a typical cooling season, divided by the total electric energy input during the same period. The higher the SEER rating, the more efficient the system is in converting electricity into cooling power.

These new requirements aim to enhance the overall energy efficiency of residential split A/C systems. By raising the bar for SEER ratings, manufacturers will need to develop and produce units that meet these stricter guidelines. This shift towards higher SEER ratings will result in reduced energy consumption and lower utility bills for consumers.

SEER Rating Basics

Understanding the basics of SEER ratings is essential in comprehending the significance of these new efficiency standards. SEER is a standardized metric used to measure an A/C system’s efficiency. It provides consumers with valuable information about how much cooling capacity they can expect from their unit relative to its energy consumption.

A higher SEER rating signifies that an A/C system can provide more cooling output while using less electricity compared to units with lower SEER ratings. For example, if you were to compare two A/C systems with different SEER ratings, let’s say 14 and 18, you would expect the unit with a rating of 18 to deliver more cooling power per unit of electricity consumed.

Nationwide Standards

The implementation of these new efficiency standards ensures uniform guidelines across the country. By setting consistent regulations, it creates a level playing field for manufacturers and helps consumers make informed decisions when purchasing A/C systems. These nationwide standards aim to improve energy efficiency on a broader scale and reduce the overall environmental impact of residential cooling.

For manufacturers, these standards mean that all their products must meet the same energy efficiency requirements, regardless of where they are sold within the country. This uniformity simplifies the manufacturing process and allows manufacturers to streamline their production lines accordingly.

On the consumer side, nationwide standards provide peace of mind knowing that all A/C systems available in the market meet certain energy efficiency criteria. This enables consumers to compare different models based on their SEER ratings and make more informed choices that align with their energy-saving goals.

Impact on Energy Consumption

Reduced Energy Bills

One of the significant benefits of the new DOE energy efficiency ratings for residential split A/C systems in 2023 is the potential savings on monthly energy bills. With these updated standards, homeowners can expect to see a noticeable decrease in their overall energy consumption, resulting in lower electricity costs.

The key factor behind this cost-saving advantage lies in the higher Seasonal Energy Efficiency Ratio (SEER) ratings required by the new regulations. SEER measures the cooling output of an air conditioning system over a typical cooling season divided by the total electric energy input during that same period. In simpler terms, it indicates how efficiently an A/C unit uses electricity to cool a space.

By upgrading to a system with a higher SEER rating, homeowners can significantly reduce their energy consumption and subsequently lower their monthly utility bills. For example, an older A/C unit with a SEER rating of 10 may consume twice as much electricity as a newer model with a SEER rating of 20 to achieve the same level of cooling. This substantial difference translates into tangible cost savings for homeowners over time.

Not only do these improved efficiency standards lead to immediate financial benefits for homeowners, but they also offer long-term advantages. By investing in an energy-efficient split A/C system, homeowners can enjoy consistent cost savings year after year.
