Frequently Asked Questions

Surge protection devices install at your main panel and divert excess voltage from lightning strikes or power fluctuations safely to ground, protecting every circuit in your home from damaging electrical spikes.

Most homes in Supply need a 12kW to 22kW generator for essential circuits, while whole-home coverage typically requires 20kW or larger, depending on your HVAC system and appliance loads.

Yes, whole house surge protectors are designed to handle direct and indirect lightning strikes by clamping voltage spikes before they reach your home's wiring and sensitive electronics.

Most standby generator installations are completed in one to two days, including electrical connections, transfer switch installation, fuel line hookup, and final testing for proper operation.

Coastal areas experience frequent thunderstorms and higher lightning activity, creating more power surges that can destroy electronics and appliances. Salt air also increases electrical system vulnerability.

Generators need routine oil changes, air filter replacements, and annual inspections to ensure reliable operation. Most manufacturers recommend professional service every six months or 100 hours of runtime.

Yes, when installed at the main service panel, surge protection devices guard every outlet, appliance, and hardwired system throughout your entire home from voltage spikes and power surges.

Yes, properly sized standby generators can run HVAC systems during outages. Central air typically requires a 14kW or larger generator, while heat pumps may need even more capacity.

Surge protectors should be replaced after major lightning events, every 5-10 years as components age, or when indicator lights show the device has reached its protection capacity.

Home generators typically run on natural gas or liquid propane. Natural gas provides unlimited fuel supply, while propane offers independence from utility lines but requires tank refills.

It depends on your existing panel's available capacity. A licensed electrician performs a load calculation to determine whether your panel can support a dedicated 240V, 40–50A circuit — and M.L. Sawyer includes this assessment as part of every EV charger installation in Brunswick County so nothing is left to guesswork.
