Expected vs Measured Supply Air
measured supplyexpected (from ambient)
Baseline is built from ambient, the true cause — not return. When crews prop the room with other units (doors open, cross-blowing fans), return reads falsely cool; ambient can’t be faked. Measured drifting above expected = the unit losing capacity.

Component Testing
Capacitors · measured µF from voltage & current
With the unit running, measure the AC voltage across the capacitor terminals, and clamp an ammeter on one capacitor lead to read its current. Enter the nameplate rating and your two readings, then calculate.
Formula: µF = current ÷ (2π × frequency × voltage).
