⚠️ Refrigerant Standards Update for 2025
The HVAC industry is undergoing a major transition in 2025 as older refrigerants like R-410A are being phased out due to environmental regulations. New systems must use low-global-warming refrigerants such as R-32 and R-454B.
- R-32: A high-efficiency refrigerant with reduced environmental impact. Learn more
- R-454B: The preferred replacement for R-410A, used in newer residential systems. Explore the details
If you're replacing an A/C unit or planning an upgrade, Comfort Zone HVAC will help you choose a compliant, long-lasting system. Our technicians are trained to install and service all modern refrigerant-based equipment under the latest EPA guidelines.
