How Our Generator Installation Process Works

If you’ve never installed a generator before, it can seem overwhelming at first, but we make it simple. Our team will guide you through every step, so you always understand what’s being done and why.

Here’s what the process looks like:

  • Site visit and evaluation. We begin by visiting your property to determine the best location for your generator. During this step, we assess your electrical setup, power usage, and panel capacity to determine the right solution for your needs.
  • Personalized recommendations. Once we understand your property’s energy needs, we recommend the ideal generator type and size, whether you want full-home coverage or targeted backup for key circuits.
  • Professional installation. Our licensed technicians handle wiring, panel integration, and transfer switch installation with care and precision, always adhering to local codes and manufacturer standards.
  • Testing and walkthrough. Before finishing, we test your system under load and walk you through how it operates, so you’ll feel confident using it when needed.
  • Ongoing care. After installation, we offer maintenance and inspection services to help your generator stay in optimal condition throughout the year.

Generator Maintenance & Service

A generator is only as reliable as its upkeep. Like any equipment, it needs regular care to stay ready when you need it most. Routine maintenance prevents small issues from becoming costly problems and keeps your system running efficiently year after year.

Most manufacturers recommend a full inspection at least once a year; however, generators that run frequently, such as in commercial settings or during storm season, may require servicing every six months.

At NLMS, our maintenance service covers:

  • Routine testing and performance checks
  • Oil and filter replacement
  • Battery inspection and replacement
  • Cooling system and fuel system checks
  • Troubleshooting and repairs

Our FAQ

Find Quick Answers About Our Work and Processes
  • Do we need to have a company representative be present when work is going on?
    You do not need to be present when work is completed. We are licensed, bonded, and insured for your protection, and all of our electricians are thoroughly screened and background checked. If you have questions about the work being completed, then we do encourage you to be present at the time the technician arrives. It comes down to your preferences, and we will work with you to accommodate your schedule.
  • How soon can we get scheduled?
    We do our very best to try and work within your time frame, allowing for all materials to be received so we can arrive, inspect, and install.
  • Do you offer any warranty on your work?
    Yes, NLMS does warranty our labor and materials. Materials come with manufacture warranties. Some manufactures offer a warranty up to 10 years, but most are at least backed by a 5-year limited warranty. NLMS also warranties our craftsmanship. Normal labor warranties are backed by 1 year; however, we believe all issues deserve a full inspection as to why the situation happened and if in any way the issue was installation related, NLMS will be happy to further investigate and work with you on providing a solution. You are in good hands with us, it is our reputation on the line and that cannot be compromised!
  • What are the advantages of LED lighting over Fluorescent or CFL?
    Most fluorescent lights and compact fluorescent lights (CFLs) contain mercury among other hazardous materials. As such, these lighting products must be disposed of carefully and properly, so that they do not contaminate landfills or cause danger to anyone. Fluorescent lights are also subject to flickering, and some people can be very sensitive to this, and even experience strained eyes, headaches, and even migraines. On the other hand, LED lights utilize solid-state technology, which enables stable dimming without flickering.  Additionally, fluorescent lights can take a significant amount of time to reach their full brightness levels, especially when it is cold. LED lights, on the other hand, turn on instantly in any environment and temperature.
  • What’s better for lighting, incandescent, halogen or LED?
    LED lighting is more efficient than incandescent or halogen lighting by approximately 85%, partly because approximately 80-90% of energy emitted from those bulbs gets converted to heat instead of light. Because of this, LED lights do not require nearly as much energy to produce the same amount of light. By design, LED lights will also last about 50x longer than incandescent or halogen lighting.
