Residential Service Upgrades: When, Why, and How to Power Your Home Safely

As homes become more energy-dependent, many older electrical systems struggle to keep up. From electric vehicle chargers and heat pumps to renovated kitchens and finished basements, today’s power demands are far greater than they were even 20 years ago. That’s where residential service upgrades come in.

At CIS Limited, we help homeowners upgrade their electrical service safely, efficiently, and in full compliance with Canadian Electrical Code requirements.

What Is a Residential Service Upgrade?

A residential service upgrade involves increasing the electrical capacity supplied to your home. Most older houses were built with 60-amp or 100-amp service, while modern homes typically require 200 amps or more to operate safely and reliably.

An upgrade may include:

• Replacing the electrical panel

• Upgrading the service mast and meter base

• Installing new breakers and grounding

• Coordinating with the local utility for disconnect and reconnect

Signs You May Need a Service Upgrade

Not sure if your home needs an upgrade? Common warning signs include:

• Frequent breaker trips or blown fuses

• Dimming or flickering lights

• Limited breaker space in your panel

• Use of extension cords for permanent loads

• Adding high-demand equipment like EV chargers, hot tubs, or heat pumps

• Renovations that increase electrical load

If your panel is full or your system feels strained, upgrading is often the safest and most cost-effective solution.

Benefits of Upgrading Your Electrical Service

Improved Safety: Outdated electrical systems are a leading cause of residential electrical fires. A service upgrade reduces the risk of overheating, overloaded circuits, and equipment failure.

Support for Modern Technology: A higher-capacity service allows you to install EV chargers, smart home systems, air conditioning, and energy-efficient appliances without concern.

Increased Home Value: Upgraded electrical infrastructure is a major selling point for buyers and can help your home pass inspections more easily.

Future-Proofing Your Home: Even if you don’t need extra power today, upgrading prepares your home for future additions and technology.
