Superior Electrical Service

Install Generators

Stand-by Generators are a life saver when you are without power suddenly. Superior Electrical Service has been installing stand-by generators of all types and sizes for years. Having a generator is not only convenient, but helps save you the added expense of replacing what is in your refrigerator and freezer, too.

  • Residential and Commercial
  • When your power goes out, your family or business can be prepared with a back-up generator that comes on-line automatically. Small generators can be designed to power only key appliances like refrigerators, freezers, lights or even Medical equiptment. Large generators can power an entire house or business.

  • Complete Design and Installation
  • We make installing your generator simple. We build the pad, if needed, make the purchase of the generator on your behalf, and complete the installation. By taking the step of calling us now, your family or business can be spared days or weeks of disruption due to lack of power.

  • Maintenance/Service Contracts and Repair
  • We see our workmanship through to the end. We have excellent service contracts that insure you will have the maintenance and repair work you need in a timely and cost effective way.

  • 24 hour service
  • Superior Electrical Service is available to our customers 24 hours a day, 7 days per week. When you need our services, we are available to you.

  • Portable and Permanent Installations
  • Whether you need a portable generator for smaller equipment or you need a permanent larger unit, we are able to install your generator to meet your needs.

  • Temporary Needs
  • When having an outdoor event, we can install a temporary generator to make sure you have the power you need to accommodate your event.

People just like you say nice things about our service

  • We did a major remodeling of our master bedroom and bathroom and hired Superior Electrical to do all of the electrical work. They did a great job and proved themselves capable, competent, and reliable. Rich, Alex, and David will be our go-to electricians next time we need any electrical work.

  • Superior Electrical is a family owned and operated business that really does a thorough job and makes sure your problem is REALLY solved. Our garage electrical had stopped working due to some faulty wiring in the past. They came out last month and checked out the entire system and found a faulty installation of fuses, but still charged me as if it was just a small repair. Plus he taught us about what to do if the fuse--which is part of the hardwiring now--causes problems again so we can fix it ourselves. I like that.....

  • Superior Electrical came to our house when I had an outlet that was not working properly and while they where here; discovered some improperly wired items that could have caused a fire later in time. Later they told me about the ALL HOUSE Surge Protector and I was thrilled that they were able to install one for my home. So now all of my major appliances, PCs and TVs are safe. I highly recommend Supreior Electrical to all my friends and family. They are THE MOST reliable company I have ever used for electrical repair services.
