Good so far

The generator has been right on schedule with the test runs each week and ran well when my installer initially tested it. The only reason I'm not giving 5 stars yet is because it hasn't truly been tested in reality yet.... we haven't yet lost power and had our "smart" generator automatically turn on. If we do and it does, for as long as necessary, I will enthusiastically give it 5 stars!

It's too early to review

It's early times yet, so I'm not ready to rate the installation and equipment. We had some qlitches getting the stand built, in part because the Generac team wouldn't do it (too high, they said) and we had to contract that job out. Attaching the stand to our house turned out to be a bad idea, because the house shakes whenever the generator comes on. The stand should, if possible, be free-standing. Ask me after it's been through a hurricane.

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.

Generator meets our needs

We live 1 1/2 miles from the highway on a dirt road. In 1995 when Opal came through, we were without power for a week. Now that we are older, as bad as that was then, it would be a very bad imposition now. With our generator, we can keep the entire house going now and don't have to worrying about power outages.

Well spent money.

Love my new Generac, I feel so much better knowing that I'll have power during a power outtage. I live alone and it has given me a great security knowing I'll taken care of. The guys that installed it was fantastic!!! Very VERY professional. I highly recommend GTI Generac power systems.

Outstanding experience

From the very first call to the Generac dealer/installer, right through to the detailed walkthrough, this has been an outstanding experience. The instal crew was polite, professional, and really knew their business. The unit itself is sleek looking and attractive. The unit is mounted about ten feet from my home office and when it starts for the routine weekly test, it only sounds like my neighbor is mowing his lawn. Keep in mind we live on 1 1/2 acre lots so it is not loud at all. My wife couldn't even hear it running when I asked her if it was loud. Great product, excellent service.

Unbelievable project completed on time just wonderful

Unbelievable project completed on time just wonderful. I am an older woman who lives alone in the mountains of western North Carolina but I continue to work out of town . Since I am gone for days at a time I could not take a chance that I would come home to no electricity and broken pipes my Generac has been faithful from day one it is easy to look at I had it hooked up to propane to save some money and it has been working wonderfully I would never suggest anyone who lives alone and leaves their home for more than a few days to not have the wonderful power of Generac to keep things running smoothly should the power not return for a while thank you Generac and a special shout out to Doug Who was so patient with explaining all the directions for use of the Generac and for the installation is a one-of-a-kind southern gentleman and I cannot thank him enough . I love my Generac thank you

Works as expected

We've had the unit a couple of months and it has performed as advertised, we had a couple of power outages of 1 to 2 hrs each and the unit came on and switched to backup power without a hitch. A nice feature is the generator has a self test mode running once a week for 5 min so you know your generators ready to go in case of power outage. Would recommend to all.

Smaller, but powerful!

Love the smaller size, equally powerful, and talks to me! So many updates from the original generator it replaced! Very reassuring getting email alerts telling me it is testing and 'Ready to run'!!! No more guessing if it is working. Direct communication with Generex is an added bonus! Best feature ever!!
