An experienced HVAC technician can install a new AC capacitor in less than 30 minutes if it’s easy to get to, and it could cost you as little as $30 to $60 in labor, depending on your location. More commonly, the labor cost to replace an AC capacitor is in the $120 to $250 range.
Once the start capacitor’s job of starting the AC motor has been accomplished, it turns off, and the run capacitor steps in. Start capacitors typically cost $9 to $25. The average cost to replace start capacitors is $110 to $325. The run capacitor on an AC unit is often simply called an AC capacitor.
The cost of HVAC capacitor replacement ranges from $15 to $250, depending on the system and type of device you require. Labor and parts for replacing a heat pump capacitor cost between $85 and $250. The capacitor costs between $15 and $25, and labor prices vary depending on your location and system complexity.
Run, start, and blower capacitors are often the least expensive, while dual-run capacitors are on the upper end due to their complex design and role in the system. These capacitors also vary in price depending on your chosen brand, with high-end options costing $60 to $140 more. Start capacitors typically cost between $9 and $25.
The larger the air conditioning system, the larger the capacitor required because it needs a stronger current to operate. Most capacitors range from 1 µF to 60 µF, with voltage ratings between 250V to 440V. As capacitors increase in size, so does the cost. Labor is the most significant cost factor when replacing an AC capacitor.
AC capacitor replacement can usually be done in under two hours, as it’s a relatively simple maintenance task. However, complex installations can take several hours, so it’s best to call your HVAC technician when you suspect a faulty capacitor.
