Does your home's age affect surge protection?

What you need to know

Whether your home was built five years ago or 75 years ago, it can experience power surges. However, the age of your home—and more importantly, the age of its electrical system—can influence how well it's equipped to support today's electronics and appliances.

Older homes may have outdated electrical components, while newer homes often contain significantly more sensitive technology. Understanding how your home's electrical system has evolved over time can help you make informed decisions about protecting it.

Does the age of your home matter?

The short answer is yes—but not always for the reason you might think.

Power surges can affect homes of any age.

What's often more important is:

  • The condition of your electrical system
  • Whether your electrical panel has been upgraded
  • The age of your wiring
  • Whether your home has proper grounding 

A well-maintained home built in the 1970s may have fewer electrical concerns than a poorly maintained home built much more recently.

Rather than focusing on the age of the house itself, it's better to think about the age and condition of the electrical infrastructure inside it.

Older homes often have older electrical systems

Many Alberta homes built decades ago have been updated over the years, but not all electrical systems age at the same pace.

Depending on when your home was built, it may have:

  • An older electrical panel
  • Aging branch circuit wiring
  • Outdated breakers
  • Older grounding systems 

That doesn't necessarily mean the system is unsafe or incapable of supporting surge protection.

However, older electrical systems may benefit from an inspection before additional electrical equipment is installed.

If your home has undergone several renovations over the years, it's also worth understanding how the electrical system has changed.

Newer homes have more technology to protect

Ironically, newer homes often have the opposite challenge.

Rather than older electrical systems, today's homes contain more sensitive electronics than ever before.

Examples include:

  • Smart thermostats
  • Wi-Fi routers
  • Smart lighting
  • Security systems
  • Connected appliances
  • Home offices
  • Electric vehicle chargers
  • Solar inverters
  • Battery storage systems 

Many of these devices contain microprocessors and circuit boards that can be affected by voltage spikes.

According to the Institute of Electrical and Electronics Engineers (IEEE), modern homes rely on significantly more semiconductor-based electronics than previous generations, increasing the importance of protecting sensitive equipment from transient overvoltages.

Surge Protection Plan

Protect your electronics and appliances from surprise repair and replacement costs due to electrical surges.

Renovations can change the picture

Home renovations often improve comfort and functionality, but they can also create a mix of electrical systems from different eras.

For example, a home may have:

  • An upgraded kitchen
  • A finished basement
  • A new detached garage
  • A home office
  • Air conditioning added years after construction
  • An EV charger
  • Solar panels 

Each renovation may introduce additional electronic equipment.

If your electrical system has been expanded over time, it's worth confirming that the panel and wiring continue to meet your home's needs.

A qualified electrician can assess your electrical system and recommend upgrades if necessary.

It's not just about wiring anymore

Twenty years ago, many homes relied primarily on mechanical appliances.

Today's homes depend on electronics.

Consider the difference:

While these technologies offer greater convenience, they also increase the number of electronic components throughout the home.

Protecting those systems has become part of protecting the modern home.

Signs it may be time for an electrical inspection

Whether your home is old or new, a licensed electrician be worth considering if you notice:

  • Frequently tripped breakers
  • Flickering lights
  • Buzzing outlets
  • Warm electrical panels
  • Two-prong outlets
  • Recent major renovations
  • Plans to install an EV charger
  • Plans to add solar panels
  • Uncertainty about when the electrical system was last inspected 

An inspection can help identify whether your home's electrical system is ready to support additional equipment and technologies.

Helping protect homes of every age

Power surges don't discriminate based on the age of your home.

Whether you live in a century home, a suburban home built in the 1990s or a brand-new build, your electrical system may experience voltage spikes caused by:

  • Everyday appliances
  • Utility switching
  • Power restoration after outages

 

Surge protection helps reduce the impact of many common voltage spikes before they travel through your home's electrical system. Further, many homeowners also choose to use surge protector power bars for sensitive electronics, creating multiple layers of protection.
