The push to increase energy efficiency and reduce emissions continues to drive change in the HVAC industry. As a result, the government is instituting significant changes in energy efficiency criteria and ratings for both residential and commercial equipment.
Rather than viewing the regulatory changes as a problem to be solved, we embraced them as an opportunity to innovate new technologies to create an ideal product line for contractors and homeowners.
To help you understand what's changed, why, and how it affects you, we're pleased to bring you this HVAC KnowZone™ to act as a central hub where you can easily access information as it becomes available.
In 2020, a bipartisan Senate bill, known as the American Innovation and Manufacturing (AIM) act, was enacted. It sought to address global warming by ushering in the next generation of refrigerants.
In addition to the new M1 requirements, the Inflation Reduction Act (IRA) has new 2023 updates. These include enhanced tax incentives and a new state-administered consumer rebate program that encourages homeowners to upgrade to HVAC systems with heat pumps and high-efficiency air conditioners and furnaces.
For equipment manufactured after January 1, 2023, the minimum standards have changed, and a new test procedure is required. These requirements vary by region but generally increased by about 7-10%.
With a company-wide commitment to excellence, robust product processes and relentless support of the installers who turn great equipment into reliable comfort systems, we are always seeking to make the very best products possible.
When it comes to training and certifications, everyone connected to the HVAC industry benefits —contractors, technicians and even homeowners.

The US Department of Energy is changing the way EnergyGuide Labels look to reflect the 2023 rating changes. Starting January 1, 2023, all heating and cooling products will be required to bear the updated labels. Click the link to find

As the new DOE Requirements Take Effect Jan. 1, 2023, Ruud will be ready with the all-new Endeavor™ Line of Furnaces, Air Conditioners, Heat Pumps and Air Handlers. So even as regulations get tougher, your job gets easier.
Endeavor Features & Benefits
In October 2023, the U.S. EPA finalized the Technology Transitions Restrictions on the Use of Certain Hydrofluorocarbons (HFCs) under Subsection (i) of the AIM Act, establishing GWP limits for the applications that use HFCs. The Technology Transitions Rule contains a 700 GWP limit for air conditioners and heat pumps by 2025, prohibiting the use of R-410A, which has a GWP of 2,088.
This rule has had quite the journey, going back to 2020 when the AIM legislation was enacted. Responding to recent concern by industry, EPA signed an interim final rule in December 2023, regarding the installation compliance date for residential heat pump and air conditioning systems. The amendment allows for installation of higher-GWP HFC equipment manufactured or imported before January 1, 2025, to be installed until January 1, 2026.
Designing for Sustainability with Low GWP
For 2025, the Environmental Protection Agency (EPA) has set a global warming potential (GWP) limit of 700 for refrigerant used in heating and cooling systems. This new requirement will result in a 78%3 lower GWP than previous-generation refrigerants—with only minimal changes to system installation. For us, this is another step toward our continued sustainability goal of reducing greenhouse gas emissions, while still delivering an exceptional level of energy efficient, dependable comfort.

Compliance Based on Equipment Type
It is essential to get familiar with the regulation specifics. EPA delineates the equipment categories of Products, Systems and Components, and the rules are different for each.
Packaged equipment are considered "Products" and have a three-year sell-through of existing inventory. "Systems" are considered a grouping of components, such as a split ducted AC/HP or mini-split, and that compliance is based on system installation, but equipment made before 2025 can now be installed through 1/1/26. "Components" are the major elements such as an indoor coil, outdoor condensing unit or air handler, and can be manufactured for R-410A indefinitely as long as they are only used for the service of already-installed equipment and labeled as such.
California and Washington HFC Rules Overlap With EPA
There is no federal preemption of state authority in the American Innovation and Manufacturing (AIM) Act. Both California and Washington have finalized state HFC rules, and other states are also considering doing the same. It's important to note any differences between local and federal rules for your state, as the more stringent requirement prevails.
1Compliance is due by Jan. 1, 2026, if UL 60335-2-40 Edition 4 is adopted by the WA State Building Code Council by Dec. 31, 2023; otherwise 24 months following the adoption of the updated code.
2R-410A condensing units manufactured prior to 1/1/2025 can continue to be offered for service repair only.
NOTE: In CA, R-410A condensing units manufactured prior to 1/1/25 can continue to be sold for service after the compliance date.
ENERGYGUIDE 101
The FTC (Federal Trade Commission) first issued an Energy Labeling Rule in 1979. The Rule requires manufacturers of major home appliances to attach yellow EnergyGuide Labels to products and post label information to supporting brochures and websites.
Consumers should use EnergyGuide Labels to comparison shop for the best in energy-efficient solutions.
