Professional Generator Installations

Our team of professional electricians can safely set up wiring, plug your generator into the transfer switch, and can wire it directly into your service panel. Doing so will ensure that the electricity is delivered safely into your home, preventing your generator from getting overloaded. Failing to install a generator properly can result in back feeding, fires, and other safety issues. Professional generator installations are also essential to prevent carbon monoxide poisoning.

Our team of electricians will inspect your current electrical system and help you find a generator that best fits your needs and your budget. Then we will thoroughly explain the installation process and its cost before any of the work begins.

My experience with The Mister Sparky team was great. I had an urgent issue with my outdoor panel following an home inspection and Timothy was on scene a couple of hours later. He took diagnostics and made sure all my questions were answered. The second day Keith and Matthew arrived and worked together to resolve issues in both our house panels. They were both professional and responsive and took their time afterwards to review their work with me.

We had an emergency situation or subpanel was going out causing the outside breaker to get up to 150 They answered my phone call and they sent Roberto out here who helped us get the stuff we need and the pricing just right and then the journeyman came and installed it all. which they also did an amazing job. Everyone quit this company was amazing and we thank you very much from the bottom of our heart

I had three kitchen light and disposal switches go out and Roberto came to the house and replaced all three switches. He also explained some added protections I could do for my electrical system for the home. He showed me options and I am planning on doing a surge protection for the outlet once I save up the money. It was nice to have options presented to you with no pressure to purchase etc. Roberto did an excellent job and I would recommend him for any repair work for your electrical system in your homes. Great customer service and easy to schedule with Mister Sparky!

- Michelle Stelter

Excellent service and installation of a severely worn out sub panel and checking our oven that caught fire recently. Timothy, Matthew and his helper (sorry forgot your name) were respectful and professional. Very clean work. Also added a surge protector to the main panel. Thank you, well worth the investment.

- Ron Heredia

I called Mister Sparky to install two pendant lights in my kitchen. Richard Cummings Jr. was my electrician and he did an amazing job. He was efficient, courteous, and extremely knowledgeable. Within minutes, I could tell that I had called the right company. I am very satisfied with my experience, and I would recommend Mr. Cummings and Mister Sparky to anyone. I will definitely be a repeat customer.
