What is the outdoor ambient temperature for AHRI rating condition "A"?

The outdoor ambient temperature for AHRI rating condition "A" is 95°F. This standard is set by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) to provide a consistent baseline for evaluating the performance of air conditioning and refrigeration equipment under specific conditions. By using 95°F as the reference temperature, manufacturers can create a standardized environment for testing, ensuring that the performance ratings of their equipment are comparable across different brands and models. This helps to inform consumers about the efficiency and effectiveness of HVAC systems when operated in warm outdoor temperatures, enabling informed decisions for installations based on expected performance in similar real-world scenarios.
