The transition to A2L refrigerants is changing how VRF systems are designed and installed, with greater attention being placed on refrigerant charge, room size, leak detection, and code compliance. While the added sensors, controls, and design considerations have created a learning curve for contractors, industry experts say the core benefits of VRF remain.

For contractors, the shift means more planning and coordination during system design, along with continued education on A2L requirements and new technologies. Newer VRF systems can also offer benefits such as refrigerant leak detection, improved zoning, energy efficiency, and reduced refrigerant usage. Click here to read more.
