How Long Do AC Capacitors Last On Average?

How long do AC capacitors last if nothing goes wrong? The typical capacitor will last a decade, but some Carmichael households receive up to 20 years of service from this vital component in their air conditioners.

Regular AC services in Carmichael, CA, can help extend the lifespan of the capacitor and the entire air conditioning system. Lengthening the lifespan of the air conditioner capacitor also depends on recognizing when it’s about to fail and repairing it right away. Learn more below.

Why Is Your AC Capacitor Important? 

When your air conditioner needs to run, it receives the necessary startup power from its internal capacitor. This component stores the electricity it needs to start the system’s compressor motor and fan. 

Air conditioners demand more power to start up than the wiring in your home can deliver on its own. Without a functioning capacitor, your air conditioner won’t turn on, even if it is plugged in.

What Affects the Average Lifespan of an AC Capacitor?

How long do AC capacitors last, and what affects their lifespan? The average is ten years, but it won’t last nearly that long with overuse. If you constantly run your air conditioner or let its efficiency drop, you’ll put more stress on the capacitor.

When this part delivers the air conditioner’s startup power, it generates heat. The more frequently the capacitor needs to operate, the less time the cooling system has to dissipate this heat. Overheating will significantly shorten the component’s lifespan.

Another common capacitor problem is a power surge. The Carmichael area has several big thunderstorms each year. A lightning strike could affect your home’s electrical service, and capacitors typically break down faster after a significant power surge like this.

If you stick with high-quality brands and expert installers when putting in the air conditioning unit, your chances of a long-lasting capacitor are higher.

Signs Your AC Capacitor Is Close to Failing

Is your aging capacitor starting to show some signs that it’s close to failing? Watch for the following problems:

• Delayed startup of the air conditioner when it used to start immediately.
• Unusual banging or humming noises when the cooling system starts.
• No air movement from the vents.

If you suspect a capacitor problem, call us for a cooling inspection and repairs as soon as possible. If our diagnostic tests show that this key component is weakening, replacing it before it fails could save you the hassle of an expensive cooling system breakdown later.

Can I Replace an AC Capacitor Myself in Carmichael, CA?

Wondering, “How long do AC capacitors last?” If you believe your capacitor is not operating as intended, contact our cooling system experts.

HVAC capacitors are high-voltage devices. If you make an error while working near this part, you risk a dangerous electric shock and more damage to the unit. Beyond the air filter, you should never try to replace an air conditioning component on your own.

Incorrect installation is another common factor that shortens capacitor lifespans. The job requires cooling system technicians who have the tools and expertise to properly install these components. If you need us, we serve neighborhoods throughout the Carmichael, CA, region and Sacramento Metro, including El Camino Gardens, Barrett Hills, and Oakview Heights.

Do High Temperatures in the Summer Affect an AC Capacitor’s Lifespan?

Longtime residents of Carmichael, CA, know the importance of having a functioning air conditioner. Temperatures here can reach the 90s and 100s from mid-April through October. You’ll also want the cooling system to work well on days when.

Maximizing residential AC capacitor lifespans means you can enjoy your air conditioner’s reliable operation for longer. However, these components do tend to struggle in periods of consistently hot weather. Having our professionals inspect your cooling system annually for early signs of wear can catch issues before they become serious and ensure your air conditioner makes it through in one piece.
