Replacing an AC capacitor in Los Angeles typically costs $120 to $400, including the part and the service call. The capacitor itself is inexpensive, often $15 to $60 wholesale, so most of the cost is the diagnostic visit and labor. It is one of the most common and most affordable AC repairs, which is good news: a blown capacitor is frequently the real reason an outdoor unit hums but will not start, or the fan will not spin, problems that can look like a dead compressor. Pricing varies with whether you need a single-run or dual-run capacitor and the exact microfarad and voltage rating, which must match your unit. While a capacitor is cheap, it stores a dangerous high-voltage charge even after the power is off, so it is not a safe DIY part to swap. At LA Heating & Air the diagnostic fee is credited to the repair, so you are not double-paying. Call (818) 660-1062.
