The intensity and frequency of severe weather events in the United States have been on the rise for quite some time. This has led to many major power outages that can leave entire regions without electricity for days, weeks, or months during the cold winter months. The amount and severity of these outages have spiked dramatically over the past decade, causing physical, emotional, and economic hardship for Americans.

Installing Your Emergency Generator

We understand how you may be wondering what's involved in generator installation. Well, you've come to the right place.


Where Do I Start?

It is important to keep in mind this is a job we do not recommend doing yourself. We will begin by coming to your home and helping you choose the best size generator, the right fuel source, and the best location to install your generator.



What's Involved?

Installation usually takes a day or two. Our team of licensed electricians and plumbers will ensure the process goes smoothly.



How Much Will It Cost?

A simple installation can start at $2000, but costs can be considerably more depending on your particular situation. Installation costs can vary considerably from house to house due to ease/difficulty of installing your fuel source (natural gas or propane).



Installation Process

  1. The licensed electrician will install your transfer switch first.
  2. After that's installed, the team will move your generator in place.
  3. Electric lines will then be connected from your transfer switch to your generator.
  4. Once electric is hooked up, your pipefitter will make the proper connections from the fuel source to the generator.
  5. After electric and fuel is hooked up, your generator is ready to start and protect your home or business.
