According to EPA regulations, air conditioning and refrigeration equipment manufactured after November 15th, 1993 must have a servicing aperture if it contains more than how many pounds of refrigerant?

• A. One pound
• B. Two pounds
• C. Five pounds
• D. Ten pounds

Answer: (A)

The requirement for a servicing aperture in air conditioning and refrigeration equipment is established to facilitate the safe and proper servicing of systems that contain refrigerants. According to EPA regulations, equipment manufactured after November 15, 1993, must include a servicing aperture if it contains more than one pound of refrigerant. This regulation is rooted in efforts to ensure that technicians can access the refrigerant in a controlled manner, reducing the risk of emissions during maintenance or repair. By having a servicing aperture, it allows for better handling of refrigerants, promoting environmental safety and compliance with the Clean Air Act.

The other options provide thresholds that are not aligned with EPA regulations concerning servicing apertures. Options that state two pounds, five pounds, or ten pounds exceed the limit set forth in regulations, making them incorrect. The one-pound threshold is in place to capture a wider range of systems and reinforce the importance of managing refrigerant recovery effectively.
