Answer :
Final answer:
Under EPA regulations, a leaking comfort-cooling appliance with 50 lbs or more of R-22 must be repaired and initially verified within 30 days, to reduce environmental impact.
Explanation:
Per the EPA regulations, any large comfort-cooling system, such as the one mentioned in your question containing 50 pounds or more of R-22, found to be leaking beyond the acceptable standards, must be repaired and tested within 30 days.
In more detail, when the leak rate threshold is exceeded, the owner or operator of the appliance is required to repair the appliance in a timely manner, typically within 30 days. The initial verification of the repair must also be conducted within this timeframe. The purpose of these measures is to mitigate the environmental impact that gases like R-22 can have due to their high Global Warming Potential. The 30-day window for both the repair and initial verification post-repair is critical to ensure that the unit is functioning efficiently and not contributing to unnecessary greenhouse gas emissions.
