The guys from Generac were amazing. From the installation right to them showing me how the unit works. They even showed me what to look for so i can troubleshoot by myself in case of an emergency when it really matters. The noise deadening insulation on the unit is unbelievable. It is a loud as a lawn mower. I was able to have conversation standing next to it. When it was on line and running, i put everything on in the house including my AC unit. Had no problem keeping the power on without a flicker.

We have our basement trenched, along with 3 sump pumps. The last time our power went out, our battery backup pump ran until the battery exhausted itself. When we got home, I opened the basement door to about 5 inches of water. I fired up our portable generator and plugged in. All pumped out after 25 minutes. Works fine...BUT YOU HAVE TO BE HOME to do this. I researched whole house generators and GENERAC was the best. I now have my own. No more flooded basement plus I don't have to worry about it anymore!! I should have put one in several years ago. I'm a believer!.

I am very impressed with the quality of this generator. It has a good appearance and fits very well in my backyard. The generator is reasonably quiet. I haven't yet needed it for a power outage but I am confident it will perform as it is supposed to.

The wiring connections were mislabeled so the electrician had to spend hours with product support to figure it out. It actually came from the factory with the control wire connection points mislabeled. This additional time really increased the cost of the install. This 24kW doesn't run my tools as well as the 7kW Honda I had. Never should have switched to a Generac that is rated with 3 times as much output. Never get Generac'ed again.

I've wanted to install a generator for several years now but pulled the trigger when they offered a 10 year extended warranty option for free. The install process went well but took about 11 hours to do. The finished product looked good. I wish there was an option of some colors because the buscuit color sticks out against a darker color house. The dealer, Lee Legler, did a great job and answered all my questions. The first test run went well. I also like the app you have that lets the homeowner monitor the generator's status.

After many years of multiple day power outages, i was looking for a highly reliable backup generator. The Generac 22kW generator i recently purchased answers the mail. It is a top quality product, installed by a skilled staff, and has work flawlessly. My neighborhood has lost power twice since my generator was installed and my internet, fridge, heat, and oven's operations have never been compromised. As a "plus", the output power of the generator is so clean, that i need not worry about "dirty" power damaging my electronics. Well done Generac!!

We purchased a Generac for our duplex and we’re told by our builder it was an unnecessary item. In the past few years it has more than paid for itself . The company Pierro Electrical Construction in Rockdale IL, is a great company.I especially like the fact that they have a female technician named Tammy , she has serviced my Generac for years. I would recommend this company to all .

We have had our 22KW Generator with Transfer switch a few days. We researched these generators for almost a year before picking the Generac. Our dealer did a great job in installing. setting it up and going over the details with us. We have a sump pump in the basement with a short term back-up, but the power has been off long enough for us to have to pack up a gasoline generator to keep the home from flooding. We now have complete peace of mind that not only the sump pump, but the entire house will not lose power again. It has given us the sensation of freedom from that worry ever again. We would recommend the Generac generator!

We have had this back up generator for about five years now. We have had scheduled maintenance done every year by Genstar and every year we have some sort of major problem. For the second time in a year and a half, all the oil has leaked out of the generator. The first time was from a pressure switch that went bad. I have not identified the source of the second leak. We’ve also had to replace the entire control panel and another electronic module. We have a severely brain damaged daughter who relies on electricity to power her ventilator, feeding pump, oxygen maker and pulmonary suction machine. We need something more reliable. We have spent about 40% of the cost of the generator in maintenance and repair repairs already in a relatively short amount of time.

The generator has been installed for just over a year. We live in a rural area where we have frequent power outages and the unit is very reliable. It is located next to the main entrance to our house and looks great, the running noise level is very reasonable. We recently had a problem with the transfer switch, we called an authorized service dealer and they where quick and professional
