Great unit

After the third power outage due to storms I'm convinced I don't ever want to be without my Generac again. In each case it only took seconds before the unit kicked in and out kept us comfortable. The first time, during a hurricane, we ran on it for 3 days. I forgot we didn't have electric. Even the neighbors came to check it out.

Generac Generator

I had this Generator installed about 4 months ago. The power failed only once since then and the Generator kicked in within 10 seconds. We hardly noticed the power failure. If this Generator continues to work like this (with proper maintenance) for the next 10 years--I will consider this as an outstanding investment. So far so good.

Quiet enough that I didn't know it was running.

I bought this last year when Michigan was out of power; yes, practically the entire state was out because of a massive ice storm. I was without power for 3 days, called the Genarac dealer and they installed the next day. There was a small problem, they installed the wrong size generator (18KW instead of the 22) but, because it was an emergency, they installed, but didn't bury the lines and set in the ground. They came back after the ice storm and replaced and reset. It runs for 5 minutes every Saturday. Good thing, a year later, another ice storm. Power went out and I didn't even know it. I woke up to everything running, including my robot vacuum. Wasn't till about 1/2 hour later that I realized the generator was running. My only complaint, after about 24 hours, I could smell gas (propane) in my house. I didn't know if it was just the fumes from the generator or if I had a gas leak from ice. But once the generator shut off, the smell went away. So, I guess it was just fumes.

Awesome Product

Installed in October, full 10 year warranty. Power went out on Christmas morning for just under 2 hours. Worked perfectly, turned everything on including the air conditioner and the hot tub, the wife thought I was nuts but, I wanted to put it through it's paces. Awesome product!

Love the look and features

The generator is placed behind our garage, completely masked by our yard's fence in the back yard. Can't wait to get the Mobile Link installed once it is off of backorder. I look forward to the first message being sent from the Generac to us, so we know it is functioning properly! No more power outage impacts for us!!!!!!

Should have done it sooner

We thought about getting a generator for many years but it seemed like a lot of research and a lot of money. After 20 years we finally put one in last spring. It was a considerable investment but so far we are pleased. Ours comes on every Wednesday morning and does the trial automatically which gives us some confidence. We've only had a few brief electrical outages and it did come on as needed but wasn't needed for a long time. When a larger outage occurs I feel confident that it will work and that our home can be the gathering spot for those without electricity.

Small One Time Price...Long Lasting Peace of Mind

Great product that delivers peace of mind against electrical power loss. In Oklahoma, we get occasional storms capable of incapacitating the delivery of electricity. Those storms can come in the form of high winds, tornados and ice. We do lose power from time to time....once after an ice storm, power was down for 8 days. Generac removes that significant threat of inconvenience and discomfort. It comes on every other week at exactly noon for about five minutes to check itself. It actually looks and works better than we expected. We recommend it to ours friends and children.

Excellent product for peace of mind!

Unless you are very skilled in the field, leave the install up to the professionals. Not terribly complicated, but there are enough things you need to get right that it is better to leave the install up to someone who is familiar with it. But the product is awesome. I installed this for my 84 year old mother, for my peace of mind, should there be a power outage any time of the year. Product looks nice, and runs quiet for the size unit it is. Reliable. I've had one for 6 years now and it is not a problem at all. Just change the oil and filter on a regular schedule, and I changed the battery at 5 years. Great product, buy with confidence!

Peace of mind

Although we have had only a couple occasions to rely on the Generac, it has been helpful. We no longer have to go out into the storm to hook up the portable one. The Generac smoothly operates and is much quieter than the portable was. We are assured if we are not home, everything will be fine.

The system has turned on and performed its job

I'm happy with my system. I haven't put it to full service but my son mentioned it had kicked on when the neighborhood had a power outage. The service installation personnel was very professional and knew his product . Mr. Woodrome took the time to explain things, his recommendations, work ethic is commendable. He set my doubts to rest.
