Rated 4.9 out of 5 by 134reviewers.
Rated 5 out of 5 by Outage Insurance We live in a rural area of southeastern Michigan, where power outages are frequent. After installing our 11k Generac, we never have to worry about losing power again. Typically when you lose power it is never a good to be without it, such as getting ready for work, dinner time, or late evening. We first looked at the 8k model, for basic needs, such as lighting, heat, water, stove, refrigerator. But the price difference to go to 11k was not that much, and it allowed us a few extra circuits for convienence. June 23, 2016
Rated 5 out of 5 by A reliable and quality standby generator Our generator is 10 moths old, and has not failed us through several power outages. It is on-line and generating power within minutes of a power loss. I am notified via my smart phone when it goes into it's weekly exercise, and again when it is back on line and ready.It has been a real comfort to know that our house is never without power, especially when we are away. I recommend this generator to anyone looking for a quality product that is reliable, built to last, and easy to maintain. June 22, 2016
Rated 5 out of 5 by With propane fuel great feature This is my third home with General purchased, no problems with any units. With propane fuel there is ease of operating not filling with gas. Installation was easy all lines well marked and instructions were well writtenWhen power goes out the system is always ready June 22, 2016
Rated 4 out of 5 by Nice generator extremely happy with my choice. the dealer i used was awesome. he patiently sat down with me and answered all my concerns. he also did not try to up sale me. he gave me the right size unit for what i wanted to cover. the 11k allows me to run about 90% of my home which is more then enough during a power failure. we've used it a couple times and it kicked on without a hitch. only thing i've learned is that periodically you have to make sure all the bolts are tight due to the vibrations of the generator. we did have a small oil leak due to loosened bolts which my installer fixed for a fair fee. June 22, 2016
Rated 5 out of 5 by Quality peace of mind! After much research we invested in a Generac for our peace of mind. The 1st time it kicked on for an outage, we ran around turning everything on to "test" the unit, you will too, it performed flawlessly. You never have to think about it, but it feels good to know it's there.. READY to run my whole house. May 23, 2016
Rated 5 out of 5 by Installed and Ready Earlier in the year, my wife and I decided on having a backup generator installed. We opted for a unit that provided the basic backup features in case of a power outage. Since moving here just over a year ago, we have already experienced four outages and with a blind elderly mother living with us, that makes life difficult.After some research, we decided on the size and made the call. Our selected dealer / installer responded immediately and after their survey, we completed our selection and set up the installation date.We now have a brand new generator installed and doing its weekly test run. So far, since the installation, we have had no outages but there have been plenty of opportunities owing to the spring storms in our area.We are extremely pleased with the installation, the installer and the services they provide.If we never need the generator, that is fine by me but I know it is sitting there ready to go if we do. May 7, 2016
Rated 5 out of 5 by Working flawlessly I Have had it for over a year now and it just sits there quietly until it's called upon when the power goes out. Then it turns Into a power pumping monster without hesitation.High winds a few weeks back blew a tree over the powerlines and the they snapped.Within 20 seconds my Generac was up and humming.Easily powering my home.And, it kept on running for the next 6 hours with out any issues.Once the power company had made the repairs and juiced up the lines again the generator quietly and automatically went back into hibernation until next time.And there will be a next time. But I'm not worried.One of the best investments for my family and my home.I'm glad I purchased it. April 8, 2016
Rated 5 out of 5 by Cottage Generator We've had this generator for just over a year. It's very reliable especially when paired with Mobile Link which sends a text when it's testing or when power is out at our cottage. Also, it's easy to find firms who will perform the annual maintenance service.Wouldn't hesitate to recommend. April 6, 2016
