What Is A2L Mitigation Going To Look Like? W/ Clifton B.

In this podcast, Bryan and Clifton discuss the upcoming transition to A2L refrigerants, like R-32 and R-454B, and what A2L mitigation is going to look like.

These mildly flammable refrigerants will be used in place of R-410A for residential air conditioning systems due to an HFC phase-down driven by legislation and international agreements. They explain what mitigation means with A2L systems – sensors will detect refrigerant leaks, and the system will shut off and turn on the blower fan to dissipate any leaked refrigerant. The mitigation helps minimize flammability risk.

They note the new A2L refrigerants contain no propane despite some misconceptions. The fundamentals of safe installation, service, and repair remain similar but will be absolutely required for A2Ls versus more loosely followed with previous refrigerants. Taking proper time and care is crucial. Bryan and Clifton then discuss the education, training, and resources available from ESCO Group to help contractors prepare for this transition.
