A new Environmental Protection Agency regulation scheduled to take effect in 2025 will require air-conditioning equipment makers to use new refrigerants deemed sufficiently climate-friendly.
The only refrigerants being used by manufacturers that meet the EPA’s new green standards are classified as mildly flammable.
Would-be buyers of these new units may worry about safety, but the bigger issue is cost. Sensors will need to be included in equipment operating with flammable refrigerants to detect leaks and shut off systems as necessary.
Manufacturers estimate that the price of compliant equipment will increase at least 10%—hundreds of dollars per system.
The switch to flammable systems will also require additional technician training and extra installation steps that are likely to increase labor costs for installations and repairs.
