"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."

"I had Mister Sparky come out to install a ceiling fan at my house and the experience was great from start to finish. The technician was professional, showed up on time, and got everything installed quickly and cleanly. You can tell they take pride in their work and pay attention to the details. If you’re looking for a reliable electrical company that does quality work, I’d definitely recommend Mister Sparky."

Generator Install questions, answered by experts

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.
