"I served as a State-licensed inspector for the City and County of San Francisco for 23 years, overseeing electrical work on multi-million dollar projects throughout the city. During that time, I had the opportunity to inspect Carlos' work on numerous occasions. His installations were always meticulous--completed per plan and strictly up to code. It was clear then, as it is now, that Carlos takes great pride in his work and genuinely enjoys what he does. That passion is evident in the quality of his craftsmanship. Since retiring from the city, I've taken on a major remodel of my home. When I learned that Carlos had started his own business, I didn't even consider anyone else for the job. He handled all the electrical work for my project, including 100% new wiring and trim out of electrical outlets, and lighting. He upgraded the main service to 200 amps, installed three subpanels, and set up two EV charging stations--I highly recommend Shadow Electric!"

Generator Install questions, answered by experts

Costs range from $500 to $2,500, depending on generator type and installation complexity.

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.
