What to Know About the New Federal Regulations for Energy Efficiency

The Department of Energy (DOE) continuously implements rules aimed at reducing energy consumption and pollution in the United States. With the most recent 2023 HVAC regulatory changes now in effect, you could wonder if the changes impact new AC units, energy efficiency and the need to replace your existing AC system. Here are the answers to many of the frequently asked questions on the changes.

Why Did the DOE Make HVAC Regulatory Changes?

The new regulations, which took effect on January1, 2023, impact new air conditioning systems and heat pumps. These modifications are designed to standardize and optimize energy efficiency, produce more environmentally friendly options and establish new standards for refrigerants and testing methods.

How Is Heating and Cooling Efficiency Measured?

All air conditioners and heat pumps have a seasonal energy efficiency ratio (SEER) specifying the level of cooling output in British thermal units or BTUs over a regular cooling season divided by the electricity consumed. The higher the SEER rating, the more energy efficient the system is, as it can remove the same quantity of heat using a reduced level of energy. This rating system has been an industry standard since the 1970s, enabling consumers to easily evaluate different AC units and choose ones that meet their energy efficiency needs.

Many ACs also earn an energy efficiency ratio (EER) calculated by dividing the cooling output (BTUs per hour) by the electrical power input (in watts) at a single point in time. Unlike SEER, EER does not factor in seasonal changes and instead measures the unit’s efficiency during peak performance. EER is used for determining an air conditioning system's operation during the hottest days of the year.

Heat pump heating efficiency is judged with the heating seasonal performance factor (HSPF). This ratio finds the total heating required during the heating season (in BTUs) divided by the total watt-hours of power consumed. Similar to SEER and EER, a higher HSPF rating indicates greater energy efficiency. HSPF has been a common heating efficiency measurement since the late 1980s.

How Are SEER2, EER2 and HSPF2 Different?

SEER2, EER2 and HSPF2 are the latest ways to evaluate air conditioner and heat pump efficiency. These brand-new standards give homeowners a more precise understanding of their energy use when they buy a particular AC unit or heat pump.

SEER2-compliant models also use updated refrigerants with reduced global warming potential (GWP) and ozone depletion potential (ODP) compared to previously used refrigerants. Outdated R-22 (Freon) and R-410A (Puron) will be recovered and sold for repairing older units, but they won’t be allowed in new HVAC systems.

What Are the New 2023 Federal Regulations for Energy Efficiency?

The changes in HVAC system assessment requirements mean SEER2, EER2 and HSPF2 are more accurate. They entail testing equipment under more practical field conditions, accounting for ductwork and static pressure, which SEER, EER and HSPF ratings don’t factor into calculations.

The new air conditioning and heat pump energy efficiency requirements for 2023:

  • Air conditioners installed in the North: 13.4 SEER2 (14 SEER)
  • Air conditioners installed in the South: 14.3 SEER2 (15 SEER)
  • Air conditioners installed in the Southwest: 14.3 SEER2 (15 SEER) & 11.7 EER2 (12.2 EER)
  • Heat pumps installed nationwide: 14.3 SEER2 (15 SEER) & 7.5 HSPF2 (8.8 HSPF)

How Do I Find My Current HVAC Efficiency Rating?

The first place to check out is the yellow EnergyGuide label stuck to the side of your AC or heat pump. You can also check for your air conditioner or heat pump's make and model on the DOE’s Energy Compliance Certification Database.

Systems installed before 2023 will show a SEER rating. Those produced in 2022 or earlier but installed after January 1, 2023, will also have a SEER rating. All models constructed and installed in 2023 or later will get a SEER2 rating.

Notice that air conditioners manufactured before 2023 can only be installed in the Northern U.S. In the South, SEER2-compliant systems are required from January 1 onward. If a heating and cooling professional breaches these rules and the DOE punishes them, they must replace the non-compliant air conditioning without billing the homeowner.

Do I Need to Replace My Existing HVAC System?

No, the switch to SEER2, EER2 and HSPF2 only affects newly constructed and installed HVAC units. There isn't any legal need to replace your home's AC unit. Having said that, if you’re wanting to upgrade, meeting the 2023 HVAC regulatory changes will save you money on power bills and comes with more advanced features, including smart thermostats and zoning.
