Direct answers
Questions homeowners ask before moving forward
Clear answers help you decide whether the next step is a fit. Project-specific facts are confirmed during review and documented before work begins.
Why should I upgrade from 100 to 200 amps?
A 200-amp service provides double the total power capacity, allowing you to run modern high-draw appliances, central AC, EV chargers, and heat pumps safely.
How long will the power be turned off during the upgrade?
Typically, the power is shut off for 4 to 6 hours on the day of the installation while utility connections are switched.
What is the difference between a panel upgrade and a service upgrade?
A panel upgrade replaces the indoor breaker box. A service upgrade increases the overall utility power entering your home, requiring a new meter box, heavier service cable, and grounding systems.
Can my utility service lines be run underground?
Yes, we can coordinate underground trenching and conduit installation to eliminate overhead wires, improving aesthetics and storm resilience.
Does a service upgrade require utility approval?
Yes, the local utility company must review the load request, approve the meter location, and perform the final high-voltage connections.
