Best investment ever !!!!

Installed Dec 2019, Westhaven, would listen to it start up and run every two weeks for 10 minutes to keep itself ready. Power went out January 2021 for two days, it fired up 10 seconds after power went out and never shut down. Ran everything in the house no problem and we were the only ones around able to do everything we normally do in our house. Had friends come over in the morning to go duck hunting and they said it was weird as we were only home with lights on. Best investment ever !!!!!!!!

Nice Generator for Our Needs

This is our third Generac generator for a good reason. Their units simply work, and work well. Our last Generac generator made it through a hurricane and ran for three (3) weeks straight. We felt very comforted knowing that it worked so well, and g-d forbid we need to rely on our generator again, we know our newest Generac addition will be there to carry the load.

To be determined

I am extremely happy and satisfied with the performance and features of the unit. I have a 3600 sq. ft home with 7 tons of A/C. The unit handled everything I could throw at it and didn't miss a beat. However, the unit has a small oil leak at the oil filter mounting base. The installer has changed out the oil filter on 3 occasions thinking it may have been a bad batch of filters. Both he and I think it is most likely an issue with the mounting surface that may be slightly warped as we cannot see any scratches or nicks. We are working with Generac to have this issue resolved and as of yet, it has not. Other than this, I am extremely satisfied and would have put quality as excellent if it were not for this one issue.

Great product and great service

We live in Florida and don’t want to go for an extended period of time without Air Conditioning. This unit can handle our needs effortlessly. The unit is sleek and unobtrusive. It blends in with the pool equipment. The install and permit process took some time but was well worth the wait.

My wife and I now feel secure and happy if the power goes out

Vital was very professional and knowledgeable. They met every requirement we needed and were prompt with concise and accurate information about our Generac. They came out to evaluate our needs with an initial assessment and finished the project 2 weeks later in one day. The two weeks wait was due to our county inspection process. We still have final county inspection but I don't see any issue arising. We are very happy with the total package and will elect to purchase the maintenance package as well.

Works great

Works as advertised.. Power went off and a few seconds later the generator comes on and powers the entire house. We are able to run both our central AC units while simultaneously running the washer/dryer, two refrigerators, pool pump, and various lights, fans, T.V.'s, computers etc with no interruption..

Great Generator

Just bought this 22kw Generator to replace a 12kW Dayton that no longer worked. This is way better. Two things I would like to see on the website with the description and Brochures. 1. A downloadable Owners Manual. 2. Direct link to repair parts and service packages. Otherwise a great Generator. I especially like the 10 Yr extended warentee. This clinched the deal for me.

Whole Home Generator

We had a major ice storm in October 2020 in Oklahoma and we were without power for 7 days. Living in the country that seem like a lifetime. We are a total electric home and that includes the well pump. No electricity means no well pump and that means no water ! We decided to invest in a Generac and we are so happy we did - it is worth all the money we paid to have peace of mind. Over the 4th of July 2022 we had a power outage for 2 1/2 house. It was 99 degrees outside but with OK humidity, it felt like 105. Your house can heat up pretty fast but as soon as the power went off, the generator started up and we back up and running with electricity. I highly recommend investing in a Generac !!!

Whole House Automatic Switch Makes Life Easier with Loss of Power

As a lifelong resident of North Florida, I have always been concerned with the risk of losing power during hurricane season, both at home and at work. For several years, I considered having a whole house generator installed, but could not justify the cost. I had done enough research that I knew that I wanted a Generac unit, as it appeared to have become the standard in backup power units, much like Apple products has done with cell phones, and Microsoft has accomplished with computers. When Hurricane Irma left us without power for 5 days, I began researching units again, and was pleasantly surprised that the unit cost had continued to decline. With hurricane season approaching again, we decided the cost was justifiable. We had a unit installed last week. The Automatic Transfer Switch works like a charm. It senses when power is lost and automatically starts the generator. Likewise, when regular power is restored, the switch senses that and starts the generator shut down process. As the owner, I didn't have to lift a finger! While we do not ever want to face another hurricane, the likelihood of that happening is slim to none. We are now prepared. Generac has made life easier!
