What to Know About the 2025 HVAC Refrigerant Change

As we approach 2025, significant changes are coming to the HVAC industry. The government mandate to phase out certain refrigerants is set to take effect, aiming to reduce environmental impact and improve energy efficiency. Here’s what homeowners in Frederick County, Montgomery County, and surrounding areas need to know about these changes and how they can prepare.

The 2025 HVAC Refrigerant Mandate

In 2020, the American Innovation and Manufacturing (AIM) Act was enacted, authorizing a phasedown of hydrofluorocarbons (HFCs) over 15 years. Starting January 1, 2025, the Environmental Protection Agency (EPA) will enforce a global warming potential (GWP) limit of 750 for air conditioning systems. This means that R-410A, with a GWP of 2,088, will no longer be used in new HVAC equipment. Instead, newer, low-GWP refrigerants like R-454B and R-32 will be the standard.

Understanding A2L Refrigerants

A2L refrigerants are identified as mildly flammable and will replace the high-GWP refrigerants. Despite their classification, A2L refrigerants are safe and efficient. These refrigerants require updated standards and building codes for safe installation, but most HVAC contractors will continue their work as usual.

R-454B and R-32: These are the primary A2L refrigerants that will be used in new HVAC systems. For instance, Rheem has chosen R-454B as their primary refrigerant.

Myths and Facts About A2L Refrigerants

Myth 1: A2L refrigerants are highly flammable.

Fact: A2L refrigerants are difficult to ignite and have been extensively tested for safety.

Myth 2: A leak requires a complete refrigerant recharge.

Fact: R-454B can be topped off without needing to recover the entire refrigerant charge.

Myth 3: New EPA exams are required for A2L refrigerants.

Fact: Contractors with EPA Section 608 certification are already qualified to handle A2L refrigerants.

Myth 4: New tools are necessary for A2L refrigerants.

Fact: Many existing tools are already A2L-approved; check with manufacturers for compatibility.

Myth 5: A2L refrigerants can be used in existing A1 systems.

Fact: A2L refrigerants must only be used in systems specifically designed for them.

Impact on Homeowners

Positive Impacts:

Environmental Benefits: Using refrigerants with lower GWP helps reduce the carbon footprint.
Energy Efficiency: New refrigerants like R-32 and R-454B are more efficient, potentially lowering energy bills.
Future-Proofing: Upgrading to compliant systems now ensures long-term compliance and avoids costly future retrofits.

Negative Impacts:

Increased Costs: New systems may be up to 30% more expensive due to new designs and safety features.
Supply Chain Disruptions: Transitioning to new refrigerants may cause temporary shortages and delays.
Retrofit Challenges: Existing systems may require costly retrofits to be compatible with new refrigerants.
Training Requirements: HVAC technicians must be trained to handle the new refrigerants, which could lead to higher labor costs.

Preparing for the Refrigerant Mandate

Replace Aging Systems: Consider upgrading your HVAC system before December 31, 2024, to avoid higher costs and ensure compliance.
Regular Maintenance: Ensure your current system is well-maintained to avoid unexpected failures and costly repairs.
Consult with Professionals: Work with certified HVAC technicians to understand your options and make informed decisions.
