Have had this unit for 2 years and other than testing for 5 minutes once a week, it has run once for less than 10 seconds. It gives us the security of knowing, if and when we need it, it will work! The BUT is it is LOUD. Regardless of what you are told, your neighbors are going to know when it is testing. Not sure how Generac can address it, but hopefully they will come up with a solution to damping the noise on future models. Bottomline, we love the security it gives us and highly recommend this unit.

Had this installed last week right before Hurricane Irma came thru Florida. Was the only house in neighborhood that had power thru out the entire storm. Had AC, hot water, stove and all lights and outlets working. Even had pool pump running. (All other pools in neighborhood turned black or green) Had neighbors plugging extension cords into our outlets to run Refrigerators and a neighbor running his wife oxygen machine from our house. Best investment we've ever made. All my neighbors now have my installers name and number and i'm sure they will be calling!!!!

It's a nice unit and a true 14kw on either fuel source what I don't like is 5 minutes a week is not enough for exercise they should run at least 12 minutes and load exercise 4 times a year I can assure you they would have less warranty claims these things are built very well and need to exercise more than they are right now alot of people have been telling Generac this but they aren't listening to good

Initially, I was excited to invest in this generator. Installed last year just before hurricane Zeta. Ran for 2 weeks, however, low oil pressure shut the unit down at least twice. No solution to excess oil usage from Comfort Engineering Systems, who did the install. This year during hurricane IDA outage, unit shut down for low oil pressure on several occasions and when I checked oil in advance of shut down it showed low oil. Over an 11 day period I had to add 14 quarts of oil. Comfort Engineering came out and performed all test to determine where the unit was using oil, but could not find any reason. Generac needs to contact me to resolve this issue, or replace the unit.

After 435 hours of protection and 5 years of service while using a 22 kw NG model G0065512 generator after hurricane Ida in Louisiana the muffler ruptured at 1 o'clock in the morning. Generator continued running at a very high level of noise. At daylight, in a rain storm, with an umbrella, I removed panels and removed the muffler, it had ruptured at the inlet above the cooling fan for the generator sending metal fragments into the plastic fan blade. Fan was damaged but still usable. I made a repair to the muffler and re-installed. First time I actually needed generator to perform this is reason for poor quality rating.

One week after installation we lost power and my Generac engaged within 20 seconds and ran for the next four hours. This unit runs smoothly and quietly. Simple design blends nicely with my house. Looking forward its reliability this coming winter. Would recommend installation for any home for the piece of mind it gives.

It is hard to review a product that was installed on April 4, 2023 and still not operational. There have been multiple delays (installation, correcting gas line, failing electrical inspection and a faulty part). In addition, they get in no hurry to address these problems with 2 to 3 weeks in between each issue. 2 1/2 months later we have what is essentially a very expensive lawn ornament. I am hoping that we might have a working generator by no later than fall at this rate. Very frustrated and completely unsatisfied with not only Generac themselves, but their approved installer as well

We had the whole-house generator installed so we didn't have to worry about power outages in either cold or hot weather. Very pleased with its performance and the fact that it powers up and "checks itself" once a week. One less thing on our minds and back to retirement mode!

we decided to go with a whole house back up. Only name that came to mind was Generac. installation went very well. and all aspects of the project went without a hitch. when the project was complete, there were no problems and the generator started right up. it is good to know we have a generac if we need to use it.

This is the 3rd generator that we have purchased. When you live in a rural area with a farm, keeping water, lights, etc. is extremely important. With each relocation over the last 20 years, we are insistent that a Generac generator be installed. We depend on being able to continue 'as normal' in all conditions. The generator has really been a great selling point for previous homes as well.
