Curious about what a generator installation entails? You’ve come to the right place!

Home Generator Consultations

Installing a home generator is far from a DIY endeavor. It all starts with a visit from our team to your home. During this visit, we’ll guide you through selecting the ideal Generac generator size and fuel source, and pinpoint the best installation spots for both your generator and transfer switch. Trust our expertise to ensure a seamless and effective setup that fits your specific needs and requirements.

The Home Generator Installation Process

Most installations require about one to two days to complete, and our team will manage every aspect of the process on your behalf. Rest assured, we’ll organize a skilled group of licensed electricians and plumbers to ensure the installation is executed meticulously and meets all necessary standards. Your peace of mind is our priority throughout the entire process.

Here’s how it works:

  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 electricity is hooked up, your pipefitter will make the proper connections from the fuel source to the generator.
  5. After electricity and fuel are hooked up, your generator is ready to protect your home or business.

Typical Costs of Installation

Installation costs vary significantly from home to home, depending on how easy or difficult it is to install your fuel source (propane or natural gas). A simple installation can start at $2,000, but costs may be substantially more based on individual situations. We recommend a professional site survey for a more accurate quote.

What about permits?

Kick your feet up and rest easy. Where required, we will handle all local permitting and ordinance compliance so you don’t have to.
