HVAC technicians have used standardized refrigerants like R-22 and R-410A across all brands for decades. In 2025, all HVAC manufacturers must use A2L refrigerants, such as R-32 and R-454B, which offer lower environmental impact, improved energy efficiency, and enhanced safety. This change introduces the need for technicians to manage multiple A2L refrigerants.
RectorSeal provides a range of products designed for reliable compatibility and performance with A2L refrigerants to support this transition. Below is an overview of these solutions and their benefits for HVAC professionals.
A2L Refrigerant Benefits
Transitioning to A2L-compatible products ensures regulatory compliance, reduces emissions, and enhances system efficiency and safety. It prepares HVAC professionals to meet future demands with reliable, high-performance solutions. Here are three benefits of A2L refrigerants:
- Lower Environmental Impact: A2L refrigerants have a lower global warming potential (GWP), reducing the HVAC industry’s carbon footprint.
- Regulatory Compliance: These refrigerants meet evolving environmental regulations, aligning HVAC systems with global sustainability goals.
- Energy Efficiency: A2L refrigerants improve system energy efficiency, reducing operating costs and enhancing performance.
How Does RectorSeal Ensure A2L Compatibility?
At RectorSeal, we verify A2L compatibility through focused chemical compatibility testing. Our engineering team rigorously tests products under various conditions to ensure seamless performance with A2L refrigerants. Additionally, since A2L refrigerants share similar miscibility and viscosity characteristics with R-410A, the risk of chemical incompatibility is low, further ensuring product reliability and safety.
Can RectorSeal Products Be Used with Legacy Refrigerants?
Absolutely. RectorSeal products meet the diverse needs of the HVAC industry. They are fully compatible with traditional refrigerants, such as R-22 and R-410A, and the newer A2L refrigerants, where applicable, offering HVAC professionals the versatility required for various systems.

For as long as most HVAC technicians can remember, all manufacturers of HVAC equipment used the same refrigerant. Whether it was R-22 or R-410A, regardless of the HVAC brand, the refrigerant was constant. Over the years, HVAC refrigerants have changed, making systems more energy-efficient and less damaging to the environment. Refrigerant leaks contributed to the depletion of the Ozone layer surrounding and protecting our planet. HVAC refrigerants and similar chemicals have been regulated to enforce the use of products that cause less harm when entering the atmosphere.
Effective in 2025, all HVAC manufacturers must use refrigerant class, A2L, in all air conditioning or heat pump systems. Currently, several types of A2L-classified refrigerants are being prepared for the marketplace. The primary refrigerants are identified as R-32 and R-545B. HVAC technicians will have to deal with multiple A2L refrigerants as they install, service, and maintain a variety of ducted and ductless HVAC systems. In short, A2L HVAC refrigerants are considered a global necessity due to their lower environmental impact, compliance with regulations, improved safety profile, energy efficiency benefits, and their role in driving sustainability in the HVAC industry.
Although refrigerant choices may represent a learning curve and require additional training, it’s comforting to know that regardless of the A2L refrigerant blends, RectorSeal has a variety of products that perform flawlessly with any A2L refrigerant.
