A power outage in Cotati, CA is manageable when your backup generator starts and runs. It becomes a serious problem when it doesn't. Whether your standby generator failed to activate during last night's outage, your portable unit won't hold a load, or you're done relying on the utility grid and want a whole home generator installed before the next storm season — Jc Electrics is the generator repair and installation team Cotati residents and businesses call when response time and technical accuracy both matter.
We don't send a general handyman to generator problems. Our licensed electricians and trained generator technicians diagnose, repair, and install residential and commercial generator systems with the depth of knowledge that these critical power systems demand. If your generator is down, we treat it as the emergency it is.
Our Generator Services in Cotati
Emergency Generator Repair Services
A generator that fails during an active power outage isn't a scheduled service call — it's an emergency. Jc Electrics provides priority emergency generator repair response throughout Cotati, CA. We dispatch fast, arrive equipped for the most common failure scenarios, and diagnose accurately using the testing equipment that on-site generator repair requires. Whether the failure is electrical, mechanical, or fuel-related, we get to the cause and address it — not patch it temporarily and leave.
Backup Generator Installation (Home Standby Systems)
A properly sized, correctly installed home standby generator is the most reliable backup power solution available to Cotati homeowners. Unlike portable units, standby generators start automatically within seconds of a power outage — with no manual setup, no extension cords, and no fuel storage management required. We size standby generators based on your actual critical load requirements, handle all electrical connections including automatic transfer switch installation, manage the permitting process in Cotati, CA, and commission the system with a full load test before considering the installation complete.
Automatic Transfer Switch Installation & Repair
The automatic transfer switch (ATS) is the device that detects a utility outage, disconnects your home from the grid, and starts your generator — all without you touching anything. A failed ATS means a generator that never activates when the power goes out. We install new ATSs for homes that don't yet have a standby system, and repair or replace failed ATSs for existing generator installations throughout Cotati. Every ATS installation is tested through a complete simulated outage sequence before we leave.
Generator Diagnostics & Troubleshooting
A generator that cranks but doesn't start, a unit that starts and immediately shuts down, a generator that runs but underperforms under load — these problems require systematic diagnosis, not replacement of components on a guess. Our Cotati, CA technicians use proper testing equipment to trace generator faults to their specific source, confirming the diagnosis before recommending any repair. This approach saves time, money, and the frustration of a repair that doesn't resolve the actual problem.
Generator Maintenance & Tune-Ups
A standby generator that sits inactive for months between test cycles accumulates the service needs that cause failure at exactly the wrong moment. Annual generator maintenance — including oil and filter replacement, spark plug inspection, battery load testing, fuel system assessment, control board diagnostics, and a full transfer switch exercise — is the investment that makes emergency response reliable when it's needed. We provide maintenance service for all major generator brands in Cotati, including Generac, Kohler, Cummins, and Briggs & Stratton.
Portable Generator Repair
Portable generators face different stress patterns than standby units — irregular use, varied storage conditions, varying fuel quality, and physical transport all contribute to the carb fouling, stale fuel problems, ignition failures, and AVR issues that portable generator owners in Cotati, CA commonly experience. We repair portable generators from all manufacturers, including Honda, Generac, Champion, and Yamaha, diagnosing and fixing the specific fault rather than advising replacement for units that are genuinely repairable.
Whole Home Generator Installation
A whole home generator powers everything in your Cotati property during an outage — not just a few circuits. This requires a generator sized for the full load of your home, a transfer switch rated for your service panel capacity, and fuel supply infrastructure appropriate for a unit that may run for extended periods. We handle whole home generator installation completely, from load calculation and generator sizing through fuel supply coordination, electrical connections, transfer switch installation, and final commissioning.
Generator Wiring & Electrical Connections
Generator electrical connections — from the unit to the transfer switch, from the transfer switch to the panel, and from the panel to critical circuits — must be correctly sized and properly installed to handle the sustained loads a generator supplies under outage conditions. Undersized wiring, improper connection methods, and incorrect transfer switch integration are the most common causes of generator electrical failures we encounter in Cotati, CA. We perform generator wiring and rewiring to current NEC and local code standards on every installation and repair.
Load Testing for Generators
A generator that starts cleanly under no load may still fail when full household demand is applied. Load testing applies your generator's rated output to confirm it performs correctly under realistic operating conditions — not just at idle. We perform load testing on newly installed and existing generators in Cotati as part of commissioning, after major repairs, and as a standalone diagnostic service for owners who want confirmation their system will perform when needed.
Commercial Generator Installation & Servicing
Businesses in Cotati, CA that depend on continuous power — data centers, medical facilities, restaurants, retail operations — need commercial generator solutions engineered for reliability under sustained operation. We install and service commercial generators with the capacity planning, electrical infrastructure, and maintenance protocols that commercial-grade systems require. Commercial generator failures have direct revenue implications — our team treats commercial calls with the urgency that reflects.

Common Generator Problems & Solutions
Generator That Won't Start During an Outage
Most commonly a battery that has discharged due to inadequate exercise cycles, a stale fuel condition in the carburetor, or a failed automatic transfer switch that never signaled the generator to start. We diagnose which is occurring and address the specific cause rather than replacing all three components speculatively.
Generator That Starts, Then Shuts Down
Low oil pressure shutdown, overtemperature shutdown, overload condition, or a fault code on the control board — each requires a different repair. We read control board fault codes, test oil pressure, and assess the load at shutdown to identify the specific trigger.
Generator Running Rough or Surging
Carburetor fouling from stale fuel is the most common cause of rough running in portable generators in Cotati, CA. In standby units, air-fuel mixture issues, failing voltage regulators, or governor problems produce similar symptoms. We diagnose the specific cause before recommending carburetor replacement, which is unnecessary in most cases.
Whole House Generator That Never Activated During Last Outage
Either the automatic transfer switch failed to detect the outage or failed to signal the generator. We test the ATS through a full simulated outage sequence to identify where the failure occurred.
Our Process
We gather information about the failure mode and dispatch appropriately — same-day for emergency calls, scheduled for non-urgent repair and installation requests in Cotati.
Our technician assesses the generator's mechanical, electrical, fuel, and control systems systematically, using testing equipment to confirm the fault before recommending any repair.
We explain what we found, what repair is required, and what it costs before starting any work. No surprises on the invoice.
We complete the repair or installation correctly, test the system under load, and confirm it's operating within specification.
We provide records of the work completed and advise on maintenance intervals and the next scheduled service to keep your Cotati, CA generator reliable.
Helpful Tips for Cotati Generator Owners
- Exercise your standby generator weekly for at least 20 minutes under load. Most modern standby generators have an auto-exercise feature — confirm yours is enabled and set correctly.
- Replace generator oil annually regardless of run hours. Oil in a standby generator degrades over time even without use — annual changes keep the engine protected.
- Keep at least a half-tank of propane or a confirmed natural gas supply arrangement before storm season. Running out of fuel during an extended outage is entirely preventable.
- If your portable generator has been in storage for more than 60 days, drain and replace the fuel before attempting to start it. Stale gasoline is the number one cause of carburetor failures in portable units.
