Air conditioners rely on multiple components that work together to provide efficient cooling power to homes in Owasso during our hot Oklahoma summers.
One of the critical components is a small device called an AC capacitor, which stores an electrical charge. It provides immediate energy during the start-up process when your air conditioner cycles on and supplies energy when needed as the system operates.
As we perform repair services, customers sometimes ask, “How often do AC capacitors go out?” Read more in this post about this crucial part of your HVAC system from Quality Heating, Cooling, Plumbing & Electric, which is known for reputable AC repair in Owasso and throughout Oklahoma.
Importance of AC Capacitors and What They Do
The capacitor in your air conditioning system is essential for proper function. It stores and releases electrical energy to start and maintain system motors, including the compressor and condenser fan motor.
The capacitor works differently than a battery. Instead of releasing electricity steadily, it delivers sharp bursts when needed.
The capacitor is in the condenser unit as part of the outdoor part of your air conditioner. When the capacitor fails, the air conditioner’s motors struggle to start and run, needing the extra energy boost the capacitor provides.
The capacitor’s delivery of strong current when needed performs several functions:
- Assisted starting. As the air conditioner starts, the capacitor provides the extra energy needed to initiate the compressor. The initial start-up phase demands more energy than the static power supply can provide on demand.
- Balancing electrical energy. The capacitor helps stabilize the electrical current running through the air conditioner’s system. The greater the demands the air conditioner places on the power supply, the more the capacitor must balance voltage and current.
- Improving power factor. As the capacitor stores and releases energy, it enhances the system’s power factor, which measures energy efficiency. A malfunctioning capacitor will place higher electricity demands on the power supply, wasting energy and increasing electricity costs.
Lifespan of AC Capacitors in Owasso, OK
How often do AC capacitors go out?
Under normal operating conditions, air conditioner capacitors can last 10 to 20 years.
Some important factors that can shorten the capacitor’s lifespan include:
- Manufacturing quality
- Climate where the air conditioner operates
- Heavy air conditioner usage
The hot and humid summers in Owasso and around Oklahoma can directly affect a capacitor’s durability. Heat accelerates wear and tear, and excess humidity leads to corrosion.
Causes of Premature Capacitor Failure
Overheating, voltage fluctuations, or physical damage are common direct causes of capacitor failure.
Overheating comes from improper cooling function in the outdoor unit or heavy usage.
Voltage fluctuation is more common in areas with unstable power supply. The fluctuations place extreme demands on the capacitor.
Debris that gets inside the outdoor air conditioner unit can damage the capacitor. The capacitor can also easily be damaged during attempts at repairs or cleaning inside the outdoor unit.
Signs of Capacitor Failure
There are some warning signs that your air conditioner’s capacitor is not operating correctly:
- Difficulty in starting the air conditioning system
- Air conditioner is not blowing cool air
- Humming or buzzing sounds or burning smells coming from the outdoor air conditioner unit
- Physical signs of damage, like bulging or leaking
If you notice a sign of a failing capacitor, contact the HVAC experts at Quality Heating, Cooling, Plumbing & Electric. Our technicians can test the capacitor’s health and recommend replacing it if needed or performing other maintenance that might be necessary.
Replacing a Faulty Capacitor
Our technicians can quickly and efficiently replace a failed capacitor. We will always ensure the replacement part is the proper part for your air conditioner model. The installation will comply with top industry standards and electrical and building codes.
Capacitor replacement is not appropriate for do-it-yourself repair. The process can be risky for anyone not trained in handling electrical systems. Any part mismatch or mistake in installation can lead to more significant issues throughout the air conditioning system.
