I upgraded my Generac Guardian generator from 15KW version to a 22KW version (due to load increases). I have to say I am pleasantly surprised on the quality of power being delivered. The old generator fluctuated several hz (+-2 Hz) and had a hard time holding a steady voltage. We are using this generator to power a small data center, power quality is important as UPS don't like dirty power. This new generator holds voltage steady, the frequency is within +-0.1 Hz. Even when the large roof top air conditioning unit kicked in, the generator powered up and recovered the correct voltage and frequency within a second. The power monitoring is also a nice touch. Now I know when we loose power and if the generator kicked in or not. Although the old unit mechanically was working fine, visually the case was metal and rusted heavily. This new case is aluminum so we are expecting no rust.

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.

We are very happy with our Generac Home generator. It compliments our home. It is placed strategically to appear as a very important feature of our home. To date the unit has supplied us with power on just one occasion, an auto accident took out our power for six hours. The unit worked just as we were told it would, so while our neighbors were without power we had a normal day with all our utilities working just as they should. Thus far, we have been very impressed with the Generac unit.

We used to shudder when a storm was coming because we "knew" we would lose our electric. It was not if we would lose our electric, but would worry about how long it would be out? Could be hours to days. We can now relax since we know that within seconds our entire house will have electric with the Generac whole house generator.

Electrical and plumbing subcontractors were "hackers". Couldn't predict when they were to be at my house to do their work. Left gutter downspout in an ugly and rediculous work around. Took 2 weeks to get them back to fix downspout.Plumbers routed gas pipe with whatever fittings they had on the truck leaving the pipe as an obstical and trip hazzard.

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.

Your unit seems to operate efficiently whenever there is a interruption of electricity. It has only happened a couple times that we were aware of but it allowed us to be running without any loss of lights, cooling or heating. When should we have the oil changed and unit checked out? I think you installer said 1 year. Thanks

Unit looks good and is an upgrade from 15kw to 22kw whole house with ABT. The old one gave up the ghost during Hurricane Mathew and left me for three days without electricity. Upgraded with the new unit shortly after the hurricane and have not had a power outage that lasted more than a few seconds, so, the generator has been virtually unused except for it's weekly self test. Will know more the next time I have a major outage.

Just completed installation of our 22Kw Guardian generator. Installation was done professionally and the unit started right up. While I hope that we never have to use it, I am very relieved to know that I have purchased one of the best units on the market to keep my family warm and with full power while I am away overseas on frequent business trips.

The generator is top quality and is allowing my hundred year old mother to remain in her home with only part time caregiver service. She would be too nervous about power outages to live alone without it. We have confidence in your product. A neighbor has agreed to shovel around the generator if there is more than 8 inches of snow so it can work. It is worth the expense. Installation by one of your certified installers is important too.
