What Is An AC Capacitor?

An AC capacitor is a crucial electrical component in air conditioning systems that helps start and run the motor of the compressor and the fan. It stores electrical energy and releases it as needed to provide a boost to the motor during startup and to keep it running efficiently. 
 

What Does A Capacitor Do?

There are two main types of capacitors in an AC unit: start capacitors and run capacitors. The start capacitor provides a temporary burst of energy to the motor during startup, while the run capacitor ensures smooth, continuous operation by supplying power to the motor throughout the cycle. Without a properly functioning capacitor, the motor may not start, may run inefficiently, or could overheat. Over time, capacitors can wear out or fail due to age or wear, leading to poor performance or system failure. Replacing a faulty capacitor is essential to maintain the overall efficiency and reliability of your air conditioning system.
 

Signs of a Failing Air Conditioner Capacitor

Recognizing the signs of a failing AC capacitor is crucial for maintaining your air conditioning system's efficiency and longevity. Symptoms indicating capacitor failure can manifest in various ways, including an unusual humming noise from the unit, frequent tripping of the circuit breaker, or the AC unit failing to start. 
 
Additionally, if your air conditioner experiences a noticeable decrease in cooling performance or exhibits inconsistent airflow, these may also be indicators of capacitor issues.
 
Understanding the potential causes of capacitor problems can help you prevent future failures. Capacitors may fail due to overheating, prolonged use in high temperatures, or age-related wear and tear. Power surges and poor installation practices can also contribute to capacitor damage, leading to costly repairs or replacements.
 
Timely AC capacitor replacement is essential to avoid further damage to your HVAC system. Neglecting a failing capacitor can result in strain on other components, such as the compressor, leading to more extensive and expensive repairs. By addressing capacitor issues promptly, you not only ensure your system operates efficiently but also extend its overall lifespan. Regular AC maintenance checks can help identify problems early, allowing you to replace any faulty air conditioner capacitors and keep your home comfortable.
 

Step-By-Step Process To AC Capacitor Replacement

By following these detailed steps, a professional HVAC technician ensures that the capacitor is replaced correctly and safely, maintaining the overall health and efficiency of your AC system.

Step 1: Power Off the System

The technician will turn off the power to the HVAC system by flipping the circuit breaker that controls the air conditioning unit. Using a multimeter, the technician will verify that there’s no voltage running to the capacitor or any other electrical component before proceeding.

Step 2: Access the Capacitor

The technician will locate the capacitor in the outdoor condenser unit. Most systems have the capacitor inside the control panel of the outdoor unit. Using a screwdriver or appropriate tool, the technician will remove the screws or bolts securing the access panel of the condenser to access the capacitor.

Step 3: Discharge the Capacitor

Capacitors can hold a charge even after power has been turned off. The technician will take extra precautions to discharge the capacitor. The technician will use an insulated tool, like a screwdriver with a rubber handle, to safely short across the capacitor’s terminals (C, Fan, and Herm). This will safely discharge any remaining electrical charge from the capacitor.

Step 4: Verify the Capacitor’s Condition

The technician may use a capacitor tester or multimeter to check the capacitor's microfarad rating (µF) and determine whether it is still functioning correctly. If the capacitor is out of spec or showing signs of damage, it will need replacement. Any visual damage, such as bulging, leaking, or burnt spots on the capacitor, will indicate a failed part that needs replacing.

Step 5: Record Wiring Connections

Before removing any wires, the technician will label each connection to the capacitor, ensuring the new capacitor is connected properly. They may also take a picture of the wiring configuration to ensure accuracy. The technician will confirm the voltage and capacitance (µF) rating on the existing capacitor to ensure the replacement matches.

Step 6: Remove the Old Capacitor

The technician will carefully disconnect the wires from the old capacitor, making sure to handle the wires gently and avoid damaging the connections. If there are screws or brackets holding the capacitor in place, the technician will remove them to free the old capacitor.

Step 7: Install the New Capacitor

The technician will select a replacement capacitor that matches the specifications of the old one, including the voltage and capacitance rating. The technician will mount the new capacitor in the same position as the old one, securing it with the appropriate brackets or fasteners. The technician will reconnect the wires to the new capacitor, ensuring each wire is connected to the correct terminal (C, Fan, and Herm).

Step 8: Double-Check Connections

Before proceeding, the technician will double-check the connections to ensure they are secure and correct. Proper wire placement is essential for safe and efficient operation.

Step 9: Test the New Capacitor

The technician will turn the power back on at the breaker and check for any immediate issues or irregularities. They will turn on the AC unit and observe the system's operation. They’ll listen for proper compressor and fan operation, as well as check the temperature to ensure that the system is cooling effectively. The technician may use a multimeter to check the voltage across the terminals of the new capacitor to confirm it’s functioning correctly.

Step 10: Reassemble the Unit

Once the new capacitor is installed and functioning properly, the technician will replace the access panel and secure it with screws. Any tools or debris will be cleaned up and removed from the area.

Step 11: Final System Check and Customer Instructions

The technician will perform a final check on the entire system, ensuring everything is working as it should. They will explain to the homeowner what was done, any potential signs to look for (such as if the capacitor fails again), and provide maintenance tips for extending the life of the HVAC system.

Step 12: Documenting the Service

The technician will document the work performed, including details about the capacitor replaced, model/serial numbers, and any other relevant information. The technician will finalize the service report, process payment, and may offer additional recommendations for future maintenance or repairs.
 

AC Capacitor Cost

The cost of replacing an AC capacitor typically ranges from $100 to $400, depending on factors like the type of capacitor, your location, and whether you hire a professional for the job. The capacitor itself usually costs between $20 to $100, but labor charges for the replacement can add another $75 to $300. Consult your local Bryant dealer for a precise AC capacitor cost.
