During startup data collection for a condenser, which value is considered baseline?

• A. Temperature of Air In
• B. Supply Duct Size
• C. Panel Material
• D. Control Board Version

Answer: (A)

The starting reference point for startup data is the temperature of the air entering the condenser. This ambient air temperature directly affects how effectively the condenser can reject heat and sets the baseline for performance measurements (such as pressures and cooling capacity) taken at startup. Recording this value allows you to normalize subsequent data and identify any deviations as conditions change. The other options are fixed design or installation details—duct size, panel material, and control board version. These parameters don’t vary during startup data collection and aren’t used as the performance baseline for evaluating how the condenser operates.
