We Know These Questions Come Up Often

Homeowners in Johnston often ask similar questions about electrical work before they schedule a service visit. The answers below cover what you can expect during and after the installation.

What does a residential electrical service call include?
A service call includes an evaluation of your current system, a written estimate for the work, and a timeline for completion. The electrician identifies any code violations or safety concerns and explains what needs to be corrected.
How long does it take to upgrade an electrical panel?
Most panel upgrades in Johnston take four to six hours depending on the size of the home and whether new circuits are added. The power is shut off during the final stages of the installation, and the system is tested before the breaker box is closed.
Why do generator installations require a transfer switch?
A transfer switch prevents your generator from backfeeding power into the grid, which would create a serious safety hazard for utility workers. It also automates the switch between grid power and generator power during an outage.
What happens if my home wiring is too old to support new systems?
The electrician will identify which circuits need to be replaced or upgraded to handle the load. Older homes in Johnston often require partial rewiring to accommodate EV chargers, smart panels, or high-draw appliances safely.
When should I schedule outdoor lighting installation?
Outdoor lighting can be installed year-round, but most homeowners in Iowa schedule the work in spring or fall when weather is mild and landscaping is not frozen. Wiring is buried at code depth to protect it from freeze-thaw cycles.
