Wrong. They EPA requirements do apply to residential system. The trigger rate is a 10% leak in 12 months.
Comfort cooling- These are air-conditioning appliances used to provide cooling in order to control heat and/or humidity in occupied facilities including but not limited to
residential, office, and commercial buildings. Comfort cooling appliances include but are not limited to chillers, commercial split systems, and packaged roof-top units.
