Residential Electrical Services in San Jose
Electrical problems and upgrades do not always fit neatly into one category. Dollens Electric helps San Jose and Santa Clara County homeowners figure out what the home actually needs— whether that is a focused repair, more electrical capacity, new circuits, rewiring, EV charging, backup power or a broader system evaluation.
Diagnose First • Plan the Load • Build the Right Scope • Keep the Work Serviceable
You Do Not Need to Know the Service Name
Start With What the Home Is Doing—or What You Want to Add.
This page is the electrical-services directory. The individual service pages handle the detailed diagnosis, scope and project planning.
Residential Electrical Services
Choose the Service That Best Matches the Problem.
Each page below is built around one homeowner intent so you can get to the right information without digging through a generic list.
Electrical Repair
Breaker problems, partial power loss, dead outlets, GFCIs, switches, lighting circuits and localized wiring faults.

Lighting Installation →Sparking, Burning Odor, Overheating or Major Power Loss?
Some Electrical Problems Belong in the Urgent-Service Path.
Routine breaker, outlet and circuit problems belong on the Electrical Repair page. Active sparking, burning electrical odor, unusually hot electrical equipment, exposed damaged wiring or significant unsafe power failure should be treated more urgently.

Emergency Electrical Service →Repair, Upgrade—or Neither?
The Size of the Solution Should Follow the Problem.
A residential electrical service page should not turn every symptom into a major project.
Focused Repair
If the failure is a breaker, device, connection or individual circuit, the scope can stay focused on repairing that problem.
System Upgrade
If testing or load planning shows a real capacity, panel or widespread wiring issue, the larger project is explained separately.
Planning Only
If the electrical system can support the homeowner's goals as-is, the right answer may be to keep the existing equipment and plan around it.
Older Homes + New Electrical Demand
Many South Bay Homes Were Built for a Different Electrical Life.
Older San Jose and Santa Clara County homes may have gone through decades of remodels, added circuits, service changes and equipment upgrades. At the same time, homeowners are adding EV charging, heat pumps, induction cooking, solar, batteries and other larger electrical loads.
The answer is not automatically “replace everything.” It is to understand the existing service, wiring and distribution, then decide which parts can remain and which parts actually need to change.
Home Electrification Planning →
One Home. One Electrical System.
Panel Capacity, Circuits and New Equipment Affect Each Other.
The strongest residential electrical plan looks at the whole system without unnecessarily combining unrelated scopes.
Service & Distribution
Main panel, subpanels, breakers and feeders determine how electrical capacity is distributed through the home.
Branch Wiring & Devices
Circuits, junctions, receptacles, switches and lighting determine how power reaches the individual loads.
Major New Loads
EV charging, HVAC, appliances, battery systems and generators can change how the existing service needs to be evaluated.
Permits, Utilities & Inspection
We Handle the Administrative Side When the Project Requires It.
Not every electrical task follows the same permit path. Larger upgrades require more coordination than a focused repair.
Permits
Panel upgrades, rewiring, generators and many new-circuit projects can require permits depending on the jurisdiction and exact scope.
Utility Coordination
Projects that affect the electrical service or utility interconnection may require coordination with PG&E or another applicable utility process.
Inspection
When inspection is required, the installation is prepared around the approved scope and local inspection process.
What It Is Like to Work With Dollens
A Consistent Process Across Different Electrical Projects.
Tell Us What Is Going On
Describe the symptom, planned equipment or project goal. You do not need to diagnose the electrical system yourself.
Evaluate the Relevant System
We inspect, test or calculate what is relevant to the specific repair or upgrade instead of starting with a predetermined solution.
Define the Scope
The repair, upgrade, permit path and related work are explained before the project is expanded.
Complete & Verify
Approved work is completed, tested and closed out with the homeowner knowing what was done and what comes next.

Dollens Electric combines residential electrical troubleshooting and modernization with experience supporting existing solar and backup-power systems.
C-10 Electrical
Residential repair, panels, wiring, circuits, EV charging, generators and electrical-system planning are handled under the electrical contracting scope.
C-46 Solar + B General Building

Diagnose Before Replacing
We separate the problem the homeowner called about from larger upgrades unless the actual condition or load plan supports a broader scope.

Common Questions
Residential Electrical Services FAQs
What residential electrical services does Dollens Electric provide?
Dollens Electric handles residential electrical troubleshooting and repair, panel upgrades, rewiring, EV charger circuits, subpanels, safety inspections, standby-generator electrical integration, lighting and other approved residential electrical work.
How do I know whether I need electrical repair or an upgrade?
If something stopped working, start with diagnosis. If you are adding significant new loads or the existing equipment itself is damaged or undersized, an upgrade may become part of the project. The scope should follow the findings.
Do I need a panel upgrade for an EV charger?
Not automatically. The electrical service, existing loads, charger requirements and available capacity should be reviewed first. Some homes can use existing capacity or compatible load-management equipment.
Does an older home automatically need rewiring?
No. Older wiring should be evaluated based on condition, extent, modifications and the demands placed on the system. A localized problem may call for repair rather than full-house rewiring.
Do electrical projects require permits?
Some do and some do not. Panel upgrades, rewiring, generators and many new-circuit projects commonly require permits or inspections depending on the jurisdiction and exact scope. Dollens Electric handles the applicable path for approved projects.
Can you help if I do not know which electrical service I need?
Yes. Describe what the home is doing or what you want to add. The appropriate service path can be determined from the symptom, load or project goal rather than from the homeowner knowing the technical name first.
Do you work on existing solar too?
Yes. Dollens Electric also provides existing residential solar troubleshooting and repair, including inverter and monitoring issues, and evaluates battery backup for existing solar systems.
