When it comes to maintaining the comfort of your home, the HVAC system plays a crucial role. One of its vital components is the HVAC capacitor—often overlooked, yet essential for optimal functioning. At ACHV Services, we understand how important these small but mighty parts are to your overall system.
“An HVAC capacitor acts like a battery, providing the necessary boost to start the motor and keep it running smoothly.” – Herion K., AC expert
Regular inspections ensure that your HVAC capacitor is in good working order, preventing unexpected breakdowns and costly repairs. But what exactly should you expect during an HVAC capacitor inspection? We’ll guide you through the process, outline common issues, and explain why regular checks are necessary.

Join us as we take a closer look at what makes HVAC capacitors so important and how ACHV Services can keep them running smoothly for your family.
Signs of a Failing HVAC Capacitor
One of the most common signs of a failing HVAC capacitor is a noticeable decrease in the system’s overall performance. You might observe that your HVAC unit is not cooling or heating your space as effectively as it used to, which can be a direct result of the capacitor losing its ability to store and release electrical energy efficiently. The capacitor helps power the compressor and fan motor, both critical for cooling.
Some other signs of a failing capacitor are:
- System won’t start: Another unmistakable sign involves the HVAC system not starting at all. Capacitors provide the necessary surge of energy to start the motors. A weak or dead capacitor can inhibit this function.
- Intermittent operation: Sometimes, your HVAC system may turn on and off intermittently. This erratic behavior could stem from a failing capacitor struggling to maintain enough charge.
- Clicking noises: Hearing a clicking noise when the AC tries to turn on can also be indicative of capacitor issues. The sound occurs because the system is attempting to start but lacks the necessary power boost.
- Unusual humming sounds: A humming noise coming from the AC unit might suggest the capacitor is struggling to hold a charge, causing the motor to attempt to start without success.
- Higher energy bills: One common sign of a failing HVAC capacitor is a sudden increase in your energy bills. A malfunctioning capacitor causes the system to work harder, consuming more electricity and driving up costs.
- Physical signs: Visible symptoms, such as a swollen capacitor or leaks, are tell-tale indicators. Capacitors can deteriorate over time, causing their casing to bulge or leak fluids.
- Burned-out motor: A failing capacitor can overwork the motor, leading to burnout. If the motor burns out, it’s essential to check the capacitor since it’s often the root cause.
How Often Should HVAC Capacitors be Inspected?
HVAC capacitors should be inspected at least once a year as part of a routine maintenance schedule. Regular inspections help ensure that the system operates efficiently and can prevent unexpected breakdowns.
That said, seasonal changes (yes even here in Tampa Bay) can place additional stress on HVAC systems, making it advisable to inspect capacitors before the peak usage periods of summer and winter. This proactive approach can help identify potential issues before they lead to system failures.
Of course, if your unit is older or it’s showing signs of wear and tear, it may require more frequent inspections. Again, bi-annual inspections can help maintain optimal performance and extend the lifespan of the system.
Common Issues Found During HVAC Capacitor Inspections
When you call us out for service, one AC issue we commonly see is a bulging or swollen capacitor. This often means that the capacitor has overheated or is nearing the end of its lifespan. Overheating can be caused by various factors, including poor ventilation, excessive electrical load, or a failing fan motor. Overheating can significantly shorten the lifespan of a capacitor and lead to system malfunctions. A bulging capacitor can lead to inefficient operation or complete failure of the HVAC system!
Another frequent problem is a leaking capacitor. Capacitors contain dielectric fluid, and if this fluid leaks out, the capacitor will lose its ability to store and release electrical energy properly. This energy is important. Loose or disconnected wiring due to vibrations or improper installation, can result in intermittent operation or complete failure of the HVAC system. This can result in erratic system performance or even electrical shorts.
When maintaining HVAC units, we may also find your capacitor has corroded terminals. Corrosion can impede the electrical connection between the capacitor and the rest of the HVAC system, leading to poor performance or failure to start. This issue is usually caused by exposure to moisture or other environmental factors in the Tampa Bay area.
On some service calls, we may even find capacitors that have completely failed. A failed capacitor will not hold any charge and will need to be replaced immediately. This is often identified through testing with a multimeter or other diagnostic tools.
