An AC inspection site visit follows a defined sequence: a review of utility bills and any available equipment specifications, a visual inspection of indoor and outdoor units for obvious condition issues, refrigerant pressure measurement against manufacturer specification, and airflow/temperature differential measurement across the evaporator coil to assess actual cooling performance against rated capacity. For a facility with multiple split or package units, the inspection typically takes proportionally longer per unit than a single residential system, since each unit needs individual refrigerant and performance measurement rather than a single facility-wide assessment. BEE-backed studies show savings potential of up to 40% in cooling end-uses (Bureau of Energy Efficiency), and the site-visit process described here is specifically how that potential gets identified and quantified per unit, rather than estimated in aggregate.
This guide covers the practical site-visit sequence and typical duration, positioned as the process-focused companion to this site’s other AC-audit content, which covers technical findings (refrigerant charge, sizing mismatch) and urgency/timing considerations in more depth elsewhere.
