Living in the Texas Gulf Coast hurricanes are a natural occurrence. I am a Sr. Regional Product Support Manager for a heavy duty diesel engine manufacture with 45 years experience servicing diesel engines in Oil & Gas, Construction & Industrial, Marine, and Power Generation applications. In Sept. 2008 we went through hurricane Ike and endured six days without power afterwards. After Ike, we installed a 20kW Guardian unit and had wonderful success and a great piece of mind with the unit at our former home. After living in the Houston area for ten years, we moved away for four years, and we just moved back to the Houston area in May 2019. In preparation of our new home for hurricane season, we purchased a 22kW Guardian unit. Our first unit as well as our new unit are whole house with 200 amp ATS. Our first unit was great but this new unit is AWESOME! The controller has been improved, the unit can now be monitored wireless from anywhere using a cell phone, tablet, or laptop. It is also monitored 24/7/365 by our authorized Generac dealer. The noise level of the unit when running has been reduced substantially. Maintenance items, oil drain, oil filter, air filter, oil fill, dipstick, and battery are all easily accessible. The controller is improved, simple to operate, understand, and is accessible with ease as well. This is a well designed, well built, serviceable unit that is supported by an outstanding dealer with factory trained and certified parts and service personnel offering 24/7/365 service to their customers. And, our Generac is backed by one of the best warranties in the business. It doesn't get any better than this folks.

We are very pleased with the company that did the installation. They arrived on time after having ensured via phone that the order was in line with what we wanted. The installation team explained all aspects of the installation and the ongoing use/maintenance of the system. Work was completed in a timely fashion.

we looked at neighbor's Generac Unit and talked at length about how often the unit was used. After our conversation my wife & I decided we wanted one to protect the three deep freezers & two ice boxes we keep full of vegetables from our large garden we raise each year. We think it is beter to have it and not need it than need it and not have it.

The Generator enclosure looks great. Great balance between clean and subtle (does not draw attention from the house itself). We have not lost power yet to fully test this unit, but the self-test runs every Monday and is actually fairly quiet. Add in the 10 year warranty and the Professionalism of the Customer Service that I received while scheduling my free home site study has made this experience everything that I could have hoped for.

If the exercise time could be changed from 5 minutes to 12 minutes and the exercise speed be changed from the slow "Quiet Test" to full RPM I would give a rating to 5-stars. Other than these two significant issues, I find Generac to be a quality and reliable, made in the USA, product. It has NEVER failed me. However, because of the inadequate exercise time I feel I must manually run the generator periodically to "cook off" the condensation moisture from the oil. (NO internal combustion engine likes to sit.) The Wi-Fi reception is poor on the generator unit. My iPhone showed full strength Wi-Fi at the generator site. The generator reported zero Wi-Fi signal strength after accepting the Wi-Fi password. I ended up having the 4G LTE cellular option installed, this gave me the needed connectivity. I get an alert on my iPhone whenever the generator exercises, or is running due to a utility failure. All things considered, I would buy the generator again even with the faults mentioned above. It's hard to believe that the lack of flexibility regarding exercise time was truly an engineering decision, I fear it could be government influenced.

We have just had this unit installed. In our previous house, we lost power during the night for several hours in late Fall. As a result, one of our forced hot water heating circuits froze. Once we were able to get it thawed, water was running down the wall. In this new house, we have already lost power for a few hours, causing our sump in the basement to overflow. No more of that! We are retired and look forward to the peace of mind this Generac will provide.

This is our first generator and very pleased with all aspects of it, from the buying process to installation. You can't put a price on piece of mind with electrical outages. Our dealer has been with us every step of the way with answering questions and being honest and upfront. We're very happy with our Generac generator!

Just got our system installed after waiting several months to get. thanks to covid and factory issues. but great install and nice guys who did the work and went over how it works. been needing this for 30 years and finally could get one now no worries if power goes out. would tell people to save save to get one

Of the home improvements I have made over the past 20 years, the Generac generator is at the top of the list for reliability, dependability, workmanship and an overall feeling of being secure during bad storms, winter, and general outages. I could not be more satisfied with it's performance and the overall addition to my home's value. A great investment for every homeowner that pays off over and over again. Thank you Generac for the added security of knowing your machine is connected to my home. You've done well !!

The crew from our Dealer, Generator Works were easy to deal with and they coordinated effectively with the local utilities and natural gas supplier. The disconnects and service upgrades were conducted with minimal out of service time. The total time to install was under 6 hours including site prep and cleanup.
