My First Generac was a portable 5500K, which I used for 15 Years, I gave it to my Daughter and Son in law who are still using it when a power outage occurs. I graduated to a Generac 22K whole house with automatic transfer switch. It uses my house natural gas for fuel. Works as advertised, comes on within 8 seconds after loss of utility power, and then without delay or interruption, transfers back to utility power when it is restored. I am notified by email and instant message regardless of where I am located, when my generator is running or may need maintenance. No worries when I am gone for three months in Florida. It is programed to run / exercise each month, and I manually run it with a heavy load, 4 to 6 thousand Watts quarterly ie: oven, air conditioner, refrigerator, lots of lights. This is the best insurance I have ever purchased. Large purchase but great peace of mind. Quality product and great product support.

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!.

Before my husband died we had other types of generators that he had to start and refuel. I knew I didn't know how to operate those kinds of generators, but because of living in the Ozarks where we do experience power outages I began asking people about their generators. I got feedback from some other widows about how the Generac came on by itself, and they didn't have to do anything which sounded exactly like what I needed so ... I got one. Life is difficult enough for a woman alone, and since this product makes life easier, that's what I wanted.

From start to finish we were treated with care and respect. The Generac Team had a positive "can do" attitude. They answered all our questions thoroughly, making sure we were satisfied with our new generator. I highly recommend them for your back-up generator needs and more. A big thank you to the Generac Team.

This generator is near perfect for my needs. The only tweak I might recommend would be the ability to connect gas/electric/both under the unit (through the pad) as well as from the side (would improve the final installation appearance. That being said, looks very good and runs well and quietly. I need to add that the business you choose to install this system is key! I leveraged "Generator Works" in Denmark Wisconsin and couldn't be more pleased. If you need great results, do your homework and find a partner like the one I used.

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.

From the meeting with our Sales Rep to the field guys installing the unit to showing us the features and how to use the unit, everything was great. I hope I never have to use the generator, but it is comforting to know we will have power should a storm affect our area.

Because we live in Connecticut where Eversource is a terrible supplier of power since every major storm knocks our power out for about 6 days, this unit has been very reliable since we had it installed in 2010. We have had three power outages of 6 days in that time, the latest from Tropical Storm Isaias which knocked out power for over 700,000 customers this past week. The generator started and ran for 6 days with no problems as it always has, powering 80% of our home with a steady, even supply of power. We have two propane tanks holding just over 200 lbs. of propane so the generator can run for 6 days without a refill. After six days we get the oil changed and the tanks refilled so it can go further, but usually right when we do that the power is restored. So this generator has been perfect for us. The unit has been hit by lightning once (we live on a 600 foot mountain on the top of it) so the motherboard has been replaced, and the engine recently needed to have its rubber oil seals replaced as it was leaking a little oil, but besides that the unit has held up tremendously well. If we need to replace it we will definitely buy Generac again as we have many times over saved a lot of money by not needing to go to a hotel when our power is out since we live on well water and without water - you cannot stay home very long even if you stock up on it.

My wife and I had a Generac 22kw Guardian Series Backup generator installed when we built our home 5 years ago. We haven't really needed for any long period of time until Hurricane Matthew. We were without utility power for two days (very fortunate compared to many). Our Generac kept us fully powered and cool for the entire time!

We live in Florida where power outages are frequent. I have cancer and am going thru chemo treatments. Being without power is very dangerous to me, so this back up whole house power supply is a must. I wish insurance would pay part of the cost, but at least the generator adds to the value of our home and gives my wife and I Pease of mind. I was very pleased with the subs that did the install. They did a very nice job, thanks.
