3. 3

Frequently Asked Questions

Do you install smart lighting and EV chargers in newer Markham homes?

Yes, smart dimmer, app-controlled lighting, and EV charger installations are among our most common requests in Markham’s newer subdivisions like Unionville and Cornell.

Do newer Markham homes ever still need panel upgrades?

Sometimes. Builder-grade panels can be undersized once you add EV charging, a finished basement, or a major renovation. We assess your actual load before recommending an upgrade.

Isn’t a power bar with surge protection enough?

A power bar only protects what’s plugged into it. A whole-home surge protective device installed at the panel protects every circuit in the house, including hardwired appliances like your HVAC system that a power bar can’t cover.

Will whole-home surge protection stop damage from a direct lightning strike?

It significantly reduces the risk from lightning-induced surges travelling through utility lines, which is the most common way lightning damages home electronics, though no device can guarantee protection from a direct strike.

Do I still need power bars for my electronics?

Whole-home protection is the first line of defence, but point-of-use protection is still worth keeping for particularly sensitive electronics as a second layer.

Can a surge protective device be added to any panel?

Most modern panels can accommodate one directly. We check your specific panel during the assessment and let you know if any additional work is needed first.

How do I know if the surge protector is still working?

Every device we install has a visible status indicator, and we walk you through what to check during the installation walkthrough.

How much does whole-home surge protection cost?

Cost depends on the capacity of the device and your panel’s compatibility. It’s one of the more affordable panel upgrades we offer relative to the protection it provides.
