How Often You Should Schedule an Electrical Inspection Depends on the Age of Your Home 

Is your home overdue for a professional electrical inspection? The answer can vary depending on factors such as your home’s age, when its electrical system was installed, and whether you (or a previous owner) made any upgrades. For “newer” homes built within the past 40 years, we generally recommend scheduling an electrical inspection with a qualified technician every three to five years at the minimum. However, homes over four decades old can have electrical systems that contain dangerous, outdated components, making more frequent—even annual—inspections necessary.

When to Upgrade or Replace Residential Electrical System Components

How long parts in your electrical system last varies by age, frequency of use, type of component, and whether—or how well—it was maintained. Here’s an overview of the average lifespan of different residential electrical components and when and why to replace them.

Switches and Outlets

Switches and outlets are some of your home’s most frequently used electrical components. Though they’re typically made to last—with a life expectancy between 15 and 25 years—heavy use, poor installation, and electrical surges can negatively impact longevity. Flickering lights, sparking outlets, or hard-to-operate switches can indicate that it’s time for an upgrade.  


Wiring is a vital component in your home’s electrical infrastructure, and like switches and outlets, life expectancy can vary by type and care. For example, when properly installed and maintained, copper wiring can last 100 years or longer. On the other hand, aluminum wiring and knob and tube wiring, which were once prevalent and can still be found in older homes, have a shorter lifespan and may require more frequent monitoring for safety reasons.

Circuit Breakers

Circuit breakers protect your electrical system by preventing harmful overloads and potential fires. Although modern circuit breakers are designed to last for decades—with life expectancies averaging between 30 to 40 years—advancements in technology and safety standards might inspire you to upgrade to a more efficient, modern breaker panel with added safety features.

Light Fixtures and Ceiling Fans

Like many residential electrical accessories, the lifespan of your home’s light fixtures depends on their type, usage, and maintenance. The lifespan of light fixtures depends on the type and usage. Incandescent bulbs typically last around 1,000 to 2,000 hours, while LED bulbs can shine for 25,000 hours or more due to their improved energy efficiency. As for the light fixtures themselves, quality fixtures can last for decades, but changing design trends or personal preferences may prompt you to replace fixtures sooner.

Meanwhile, ceiling fans are durable fixtures with life expectancies of around 15 years. Additionally, regular maintenance—such as cleaning the blades and lubricating moving parts—can increase their longevity.
