• Starting January 1, 2026, the production and import of HVAC systems using high-GWP refrigerants like R-410A will be banned under the AIM Act, requiring a switch to low-GWP alternatives such as R-454B and R-32.
• This change affects equipment standards, installation practices, and requires contractors to replace rather than repair older systems, with stricter compliance deadlines through 2027.
• The transition will raise costs and create supply challenges, impacting project timelines and contractor revenues, while necessitating updated training to handle new refrigerants safely and effectively.

Starting January 1, 2026, HVAC professionals must stop using high-GWP refrigerants like R-410A in new systems. GWP, or Global Warming Potential, measures how much a refrigerant warms the planet. The new rule comes from the AIM Act and requires all equipment to use low-GWP options such as R-454B or R-32. This change affects everyone who installs or services heating, ventilation, and air conditioning units, including contractors and manufacturers. Older equipment can still be installed until January 1, 2027, but after that, only low-GWP systems are allowed. This means HVAC workers need to know the new rules and adjust their work accordingly.

How HVAC Professionals Should Prepare Now

Start by learning about low-GWP refrigerants like R-454B and R-32. These are safer and better for the environment but work differently than older refrigerants. Sign up for training classes or certification programs that cover handling these new refrigerants and the different equipment pressures. Check your current inventory and equipment. Plan to phase out models that won't meet rules after January 1, 2026. Talk to your suppliers early about ordering compliant systems and refrigerants—don’t wait until last minute because supplies are tight and prices are rising. Update your project quotes to reflect higher costs for new equipment and explain these changes clearly to customers. Begin discussing with clients the need to replace or upgrade their HVAC systems soon. Finally, review your company’s compliance plan to avoid fines or delays. Taking these steps now will help you stay ready and keep your business running smoothly as the new rules start.

Market Impact: Inventory, Pricing, and Supply Chain Changes

The shift to low-GWP refrigerants like R-454B and R-32 is shaking up how HVAC contractors manage their inventory and costs. Since these newer refrigerants are just becoming standard, they’re in shorter supply. This means distributors and contractors might face delays or have to pay higher prices. Manufacturers are raising costs by 15-25% for systems that meet the new rules. This price jump affects everything—from the upfront cost of new equipment to repairs and replacements.

Because older refrigerants like R-410A will no longer be produced or imported, finding them will get harder and more expensive. Contractors might need to stop servicing some older systems or convince customers to upgrade sooner, which changes how businesses plan and budget.

Manufacturers are also adjusting their product lines and supply chains to match the new rules, which can cause occasional shortages or slow deliveries. Staying ahead means keeping close communication with suppliers and planning purchases carefully. Overall, this market shift demands more attention to inventory and cost management for HVAC professionals.

Tools, Training, and Operational Changes for Technicians

Starting January 1, 2026, HVAC technicians must adjust how they work because new systems no longer use high-GWP refrigerants like R-410A. Instead, technicians will handle low-GWP options such as R-454B and R-32. These refrigerants operate at different pressures and have unique safety rules, so technicians need specific tools that can safely measure and charge systems with these new chemicals. Specialized gauges, leak detectors, and recovery machines designed for low-GWP refrigerants are necessary. Technicians must also complete updated training and earn certifications focused on these new refrigerants. This training teaches safe handling procedures, correct installation steps, and how to avoid cross-contamination between old and new refrigerants. Repairs on older equipment will become limited, meaning technicians will often replace entire systems rather than recharge or fix them. In the field, this means they will spend more time ensuring compliance, using the right tools, and following safety protocols. Understanding these changes is crucial to avoid violations and provide quality service.

Regulations and Compliance Deadlines for Low-GWP Refrigerants

Starting January 1, 2026, the American Innovation and Manufacturing (AIM) Act bans the production and import of HVAC systems using high-global warming potential (GWP) refrigerants such as R-410A. This rule applies to all new commercial and residential HVAC equipment made or brought into the U.S. On the installation side, HVAC contractors may still install older equipment using these refrigerants until January 1, 2027. After that date, using high-GWP refrigerants for new equipment or installations is not allowed. The Environmental Protection Agency (EPA) enforces these rules nationwide. To comply, all new HVAC systems must use approved low-GWP refrigerants like R-454B or R-32. These refrigerants operate at different pressures and safety standards, so contractors must follow updated handling procedures. Trying to recharge or repair older high-GWP equipment after these deadlines is a violation. Understanding these specific dates and the scope—production, import, and installation—is crucial to avoid penalties and stay compliant with federal law.

Key Takeaways

• Starting January 1, 2026, all new HVAC systems must use low-GWP refrigerants like R-454B or R-32 to comply with federal regulations under the AIM Act.
• HVAC contractors must replace high-GWP systems rather than repairing them, as new equipment uses different pressures and safety standards.
• Costs for compliant HVAC systems are increasing by 15–25%, and refrigerant supply shortages will affect project timelines and pricing.
• Technicians need new training to safely install and service low-GWP refrigerant systems to avoid compliance penalties and ensure proper handling.

Frequently Asked Questions

When does the phase-out of high-GWP refrigerants like R-410A take effect?

Starting January 1, 2026, it is no longer allowed to produce or import HVAC equipment using high-GWP refrigerants such as R-410A. Existing equipment made before this date can still be installed until January 1, 2027.

What are A2L refrigerants, and why do I need special training to handle them?

A2L refrigerants like R-454B and R-32 are low-GWP chemicals that are mildly flammable. Because of this, contractors must learn special handling and safety procedures to work with them correctly and safely.

How will the phase-out affect equipment availability and project costs?

Compliant HVAC systems using low-GWP refrigerants may cost 15–25% more, and supplies can be limited. This can lead to longer wait times for equipment and higher installation costs.

Can I still service or recharge older systems with high-GWP refrigerants after 2026?

You can continue servicing older equipment with high-GWP refrigerants, but new equipment must use low-GWP types. Also, some repairs may require full replacement rather than just recharging, so be ready for customer retrofit needs.
