 Trustindex verifies that the original source of the review is Google. They are a very reliable company. They communicate responsibly and always call back on the rare occasion that they do not answer their phone on the first three rings.
I have had our generator for 3 years. In the first 6 months the engine leaked oil. They came and replaced the entire engine no questions asked and at no cost.  That is what I expect of a premium service company.

I called in the morning about smelling gas and the problem was corrected a few hours later. Replaced items at no charge with service contract. Great job.

Power outages aren’t a 9-to-5 thing. That’s why we’re standing by all day every day from our headquarters in Wisconsin to answer any questions you might have.

HOME BACKUP GENERATORS: WHAT DO I NEED TO KNOW?

We know a home backup generator is a big investment. Here’s what you need to know to make an informed decision about your Generac home backup generator purchase.

How Do I Choose the Right Generator for Me?

You always to make sure you get the right size generator to power your entire home or the sections you want. When we come out to give an estimate we will let you know what will work best for you home and what options you have. The important factors are: the size of your home, how many AC units you have, how many circuits you are using, and how many AMP your electrical service is.
How Much is Everything Going to Cost?

Our most popular and important question we get. Losing power is never fun. Are you afraid the food in your fridge will spoil, you’ll loose your internet connection, and your sump pump wont work? We get it and, we will do everything we can to keep your costs down and make sure we are giving you the most competitive estimate. Several factors go into the price, but most installs are in between $11,000-$14,000, depending on size of the generator and how we are connecting the electrical and plumbing.
What's Involved in Installing a Home Backup Generator?

Installing a home backup generator is an exciting time. Your installer will prepare the installation site outside your home, place the generator, run the natural gas or LP fuel line, install the transfer switch, and make all of the necessary electrical connections. And they will make sure that your backup generator runs properly, and is ready for its first power outage.
