Why Ongaro & Sons for Electrical Work
A C-10 licensed electrical contractor that also holds the HVAC and plumbing licences, which is why the panel work never stalls the project.
Schedule Service →C-10 electrical held alongside C-20 and C-36
Most electrical work in an older North Bay house touches something else: a heat pump, a water heater, a charger. One licence holder covers all of it rather than three schedules.
Permits pulled and inspections met
Panel work, new circuits and service changes are permitted work in Marin, Sonoma and Napa. We pull the permit and meet the inspector, so the work is documented when the house sells.
Load calculations before capacity is promised
Whether a panel can take another circuit is an arithmetic question, not an opinion. We calculate it rather than eyeball the breaker spaces.
Older wiring assessed as it actually is
Knob and tube, aluminium branch circuits and ungrounded receptacles are common in this housing stock. Each has a different correct answer and a different cost.
Family-owned in the North Bay since 1932
Ongaro & Sons has held an active California contractors licence since 1963, is Diamond Certified since October 2016, and is BBB Accredited with an A+ rating since December 1995.

Read MoreFrequently Asked Questions
Can I install a ceiling fan where a light fixture is?
Often, yes, but the electrical box must be rated for fan support. A licensed electrician can verify and safely install the fan.
Can you replace outdoor fixtures with motion-sensor lights?
Yes, motion-sensor or dusk-to-dawn lights are great for security and energy savings. We’ll ensure compatibility with your wiring and location.
Do ceiling fans help reduce energy costs?
Yes, ceiling fans improve air circulation, allowing you to set your thermostat higher in summer and lower in winter while staying comfortable.
Do you install landscape lighting?
Yes, we design and install weather-resistant, energy-efficient landscape lighting to enhance safety and curb appeal.
Do you install smart switches and lights?
Absolutely, we install smart home lighting systems that can be controlled via phone, voice assistant, or automation schedules.
How do I reverse the direction of my ceiling fan? When should I do this?
Most ceiling fans have a small switch on the motor housing. In summer, blades should spin counterclockwise to push air down; in winter, clockwise to circulate warm air.
What’s the best lighting for energy efficiency?
LED lighting offers the longest lifespan and highest efficiency for both indoor and outdoor applications.
Why does my light flicker when I use the switch?
Flickering can result from loose wiring, a faulty switch, or incompatible dimmer controls. We’ll diagnose and fix the issue to prevent bigger problems.
Why is my ceiling fan wobbling or making noise?
Loose mounting, unbalanced blades, or worn motor components may be the cause. An inspection and tune-up can usually resolve the issue.
Can I add new circuits without upgrading the panel?
Possibly, but if your current panel is full or outdated, adding circuits may overload it. An inspection will determine if an upgrade is needed.
Can I install a circuit breaker myself?
Installing breakers involves working inside the panel and poses shock or fire risks. Always leave this work to a licensed electrician.
Can I stay in my home during a rewire?
Often yes, depending on the home size and scope of work. We’ll work room by room to minimize inconvenience.
