The American Innovation and Manufacturing (AIM) Act of 2020, signed into law on December 27, 2020, is significant for the future of air conditioning systems. A key focus of this legislation is the phasedown of hydrofluorocarbons (HFCs), a class of chemicals used in air conditioners and refrigeration systems.

HFCs are known for their high global warming potential (GWP), which can be thousands of times higher than carbon dioxide. Because of their environmental impact, the AIM Act mandates a gradual reduction in HFC production and consumption, pushing the HVAC industry to transition to more sustainable, next-generation refrigerants with lower GWPs.

This shift is critical for environmental sustainability but has important implications for homeowners who rely on HVAC systems. As HFC supplies dwindle, costs for maintaining systems using these refrigerants are expected to rise. Given these expected price hikes, now may be the time to consider replacing your HVAC system with a newer one.

How Do the New Regulations Affect HVAC Systems?

Starting January 1, 2025, significant changes are coming to the HVAC industry, driven by new regulations from the U.S. Environmental Protection Agency (EPA). These changes primarily focus on the refrigerants used in air conditioning systems. The refrigerants inside your air conditioner will no longer be the same, as the EPA has mandated a shift to newer, more environmentally friendly alternatives.

This change aims to reduce the environmental impact of hydrofluorocarbons (HFCs), which contribute to global warming. However, it may also have practical implications for homeowners. With new refrigerants comes the need for updated technologies and installation procedures. For example, manufacturers may need to incorporate advanced sensors and new charging methods to accommodate these refrigerants.

Is R-410A Refrigerant Being Phased Out?

The R-410A refrigerant, widely used in many air conditioning systems today, is being phased out under the AIM Act. The Act, designed to curb high global warming potential (GWP) chemicals, targets refrigerants like R-410A due to their environmental impact.

R-410A has been a common refrigerant in air conditioners because it absorbs heat from indoor air and releases it outside, an essential function in keeping your home cool. However, despite its effectiveness, R-410A is being replaced with newer alternatives with significantly lower GWPs to reduce environmental harm.

What Refrigerant Will Replace R-410A?

The new regulations mandate that refrigerants used in HVAC systems must have a GWP of 750 or less, significantly lower than that of R-410A. Enter the next generation of refrigerants: A2Ls. These are classified as mildly flammable but have a much lower environmental impact. The two most common A2L refrigerants set to replace R-410A are R-454B and R-32.

Starting in 2025, newly installed HVAC systems must be compatible with these newer refrigerants. If your system currently uses R-410A, this transition may impact future repairs and maintenance, making it essential to consider upgrading your HVAC system sooner rather than later. By staying ahead of the curve, you can avoid potential price increases and ensure your system is ready for the new regulations.

Will Prices Be Increasing for HVAC Equipment?

As we move toward the 2025 regulatory changes, homeowners and businesses can expect a significant increase in HVAC equipment costs—around 30%. This rise is primarily due to the new components required to comply with updated refrigerant regulations.

Most existing HVAC systems, which rely on R-410A, are incompatible with new refrigerants like R-454B and R-32. As a result, system upgrades, including potential modifications to piping and other components, may be necessary to ensure compatibility with the next generation of refrigerants.

While R-410A will remain available for servicing existing systems, it will gradually become scarcer as it is phased out. This reduction in supply will likely lead to higher costs for maintaining and repairing older systems.

Although the initial costs of new HVAC systems may be higher due to these changes, the good news is that the newer equipment may be more energy-efficient. This increase in efficiency can lead to long-term savings on energy bills, which may help offset the upfront investment over time.

How Can You Prepare for the HVAC Changes?

With the upcoming HVAC regulations set to take effect in 2025, now is the time to consider your options for staying ahead of the curve. Upgrading your system before the changes become mandatory could save you from the higher costs and potential headaches associated with waiting. By investing in a new system that meets the upcoming standards, you can avoid the possibility of retrofitting or replacing incompatible components later, which may be more expensive as prices rise.

If upgrading isn’t immediately on your agenda, maintaining your current system is essential. Regular maintenance can keep existing HVAC units running efficiently and reliably. Routine inspections will catch any emerging issues early, helping you avoid costly repairs or breakdowns, especially as older systems using R-410A may face rising maintenance costs once the refrigerant becomes harder to find.

Take Action Now to Save on Your HVAC System Upgrade

As we approach the regulatory changes set for 2025, now is the ideal time to consider upgrading your HVAC system. By replacing your unit before the end of the year, you could potentially avoid a 30% increase in costs due to rising equipment and installation prices. Acting now allows you to stay ahead of these changes and take advantage of long-term energy savings with a more efficient system. A new HVAC will be better suited to handle the extreme heat of our desert climate, delivering optimal comfort and energy savings.
