"Andy did a great job on wiring a new building as well as adding cat 5 wiring to my existing home. He worked around some challenging access issues for the cat 5 install and made sure everything was working before he left. The quality of all the work was outstanding. He provided some good advice in one aspect of the install in the new build, helping me avoid a costly mistake. He was very friendly, timely, and easy to work with. His prices were entirely fair. I 100% recommend Andy!"

"This team installs and services solar installations which makes the quality of their work better. They see what breaks over time on other projects and bring this experience to their own. This is my third project with them. My first was servicing a short in my system caused by an oversight by a different installer who had gone out of business."

"Having electrical issues to the point of calling SDG&E who sent a tech out immediately. Verdict: SDG&E was not the problem; the problem was in our panel. Appointment set, Jeremiah came right on time, made the diagnosis, gave us the options, and made the repairs within the hour. Jeremiah gave great information on the problem and the causes of the issue. Will use Mister Sparky in the future for any electrical issue."

Generator Install questions, answered by experts

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

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.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit
