Upcoming Changes in Refrigerants: What Homeowners in Northwest Arkansas Need to Know

As environmental concerns continue to shape industry regulations, significant changes are on the horizon for the heating, ventilation, and air conditioning (HVAC) sector. One of the most impactful shifts is the transition to new refrigerants mandated by the American Innovation and Manufacturing (AIM) Act of 2020. This legislation aims to phase down the use of certain refrigerants with high global warming potential, paving the way for more eco-friendly alternatives.

At Air Dynamics HVAC, we’re committed to keeping our customers informed and prepared for these upcoming changes. Here’s what you need to know about the new refrigerants and how they may affect your home or business HVAC systems.

The Transition to A2L Refrigerants

Starting January 1, 2025, all new residential and light commercial air conditioners and heat pumps manufactured in the United States must use refrigerants classified as A2Ls. These refrigerants have a lower global warming potential compared to current options like R-410A and R-134a. While existing equipment can continue to operate and be serviced without issue, new systems will be designed to accommodate these environmentally friendlier refrigerants.

Understanding A2L Refrigerants

Refrigerants are categorized based on their toxicity and flammability. A2L refrigerants are considered non-toxic but have a slight increase in flammability compared to their predecessors. This change necessitates redesigns in HVAC equipment to incorporate additional safety features, such as leak detection sensors and enhanced pressure testing of refrigerant lines.

The primary types of A2L refrigerants you can expect to see are R-32 and R-454B. Each HVAC manufacturer may choose different refrigerants for their systems, so it’s essential to consult with professionals when considering new equipment.

Impact on Installation and Maintenance

The introduction of A2L refrigerants means that HVAC installation procedures will become more stringent to ensure safety. Installers will need to follow updated guidelines, including:

• Enhanced Leak Prevention: Using specific joint types and protective nail plates when refrigerant lines pass through framing members to minimize leak risks.
• Refrigerant Concentration Control: Implementing measures like leak detection sensors that activate the main fan to disperse refrigerant in the unlikely event of a leak.
• Detailed Documentation: Providing permanent labels on equipment that indicate the installer and the amount of refrigerant used.
  

For homeowners, this means working with knowledgeable HVAC contractors who are up-to-date with the latest installation requirements and safety protocols.

Considerations for Different HVAC Systems

The transition may affect various HVAC systems differently:

• Centrally Ducted Systems vs. Mini-Splits: Different safety and installation strategies will apply. It’s crucial to ensure that the system installed in your home complies with the new standards.
• Multifamily Buildings: For properties like apartments or condos, additional measures may be required, such as installing refrigerant lines within fire-rated shafts to comply with building codes.
  

What You Can Do Now

To prepare for these upcoming changes, we recommend the following steps:

1. Plan Ahead: If you’re considering a new HVAC system or an upgrade, discuss the timing with your HVAC provider to ensure you get equipment that’s compliant with future regulations.
2. Consult Professionals: Work with experienced HVAC contractors like Air Dynamics HVAC, who are knowledgeable about the new refrigerants and installation requirements.
3. Stay Informed: Keep an eye on updates from manufacturers and regulatory bodies to understand how these changes may impact your HVAC system choices.
