The HVAC Technician’s Guide to the R-410A Phasedown

If you run an HVAC or refrigeration service company, you’re likely aware of the upcoming phasedown of refrigerant R-410A in the United States. It’s important to understand why this is happening, how it will affect your business, and what opportunities may arise from this transition. In this blog post, we’ll delve into the R-410A phasedown, explore alternative refrigerants, and provide actionable advice on how you can adjust to these changes and keep your HVAC business thriving.

Understanding the R-410A Phasedown

R-410A, a hydrofluorocarbon (HFC) refrigerant commonly used in air conditioning systems, is being phased down due to its high global warming potential (GWP). The Environmental Protection Agency (EPA) is implementing regulations in line with the Kigali Amendment to the Montreal Protocol, which aims to reduce the production and consumption of HFCs worldwide.

Implications for HVAC Service and Installation Companies

Regulatory Compliance: Adhering to the EPA’s phasedown regulations is crucial to avoid penalties and maintain a reputable business. Familiarize yourself with the specific timeline, reduction targets, and reporting requirements applicable to your operations. 

Replacement Equipment: As R-410A is phased down, replacing existing systems to accommodate alternative refrigerants with lower GWPs will become necessary. This presents both a challenge and an opportunity for equipment dealers to offer new systems that meet new sustainability and efficiency standards.

Skill Development and Training: Stay ahead of the curve by investing in employee training and certification programs focused on alternative refrigerants. Equipping your technicians with the knowledge and skills required to handle new refrigerants will give your business a competitive edge. For example, ESCO Institute offers online courses regarding the safe handling next-generation of A2L refrigerants. 

Exploring Alternative Refrigerants

Refrigerants like R-454B and R-32 have a significantly lower GWP than R-410a and are being increasingly adopted in residential and commercial air conditioning systems. Consider the benefits and challenges offered by understanding their unique characteristics, potential flammability risks, and equipment capability requirements.

Check your local ordinance for adoption of these A2L refrigerants. Some cities and states have implemented updated building codes to allow the use of these refrigerants, while others are still in the process. 

Adapting to the Phasedown

Partner with Reputable Suppliers: Engage with equipment manufacturers and refrigerant suppliers who can provide guidance on alternative options, availability, and pricing. Establish strong relationships to ensure a reliable supply chain during the phasedown period. Fluorofusion Specialty Chemicals is available to help you navigate the change from R-410A.

Partner with EPA Certified Reclaimers: It’s important to know that the EPA has strict regulations against venting HFC refrigerants like R-410A. This means that when repairing HVAC/R equipment, service technicians must either pump down or recover the refrigerant. To ensure proper disposal, it’s recommended to work with an EPA certified reclaim partner like FluoroFusion. They will reclaim or destroy your recovered refrigerants, even if they are contaminated with oil and acid. The best part is that they will pay you for your recovered gas, which can help turn a cost center into a profit center.

Educate and Communicate: Inform your employees and clients about the phasedown and the benefits of transitioning to more sustainable refrigerants.

Embrace Energy Efficiency: Alongside transitioning to alternative refrigerants, emphasize energy-efficient solutions to your customers. This could involve offering high-efficiency equipment, smart thermostats, and proactive maintenance services.


As an HVAC/R business owner, you are uniquely positioned to embrace the phasedown of R-410A and lead the charge. By understanding the regulations, exploring new equipment technology, and adapting your business practices, you can navigate this transition successfully while providing your customers with eco-friendly and energy-efficient solutions. Together, we can build a stronger HVAC industry that benefits both your business and the consumer.
