A fair price for AC capacitor replacement in Arizona is usually $200 to $450, and up to $600+ with after-hours fees or if other parts failed. The capacitor part itself is inexpensive; most of the cost is the diagnostic visit and labor. Confirm whether the diagnostic fee applies to the repair.
Capacitors are one of the most common Arizona summer failures because extreme heat stresses these components.
If a quote is far above this range without explanation, ask what else is being replaced. Sometimes a contactor or motor is also involved.
A dual-run capacitor (for both fan and compressor) may cost slightly more than a single-run capacitor.
