Unit was installed , tested and ready for service. Have yet to have need for it's service but I have witnessed the "automatic exercise" which started without any problem and right on the time programed. I feel confident the next power outage will not be of any inconvenience to me.

I did exhaustive research before purchasing my Generac 22kw Whole House Generator. My mother has had a Generac for almost 2 decades - zero problems, always dependable. I am an engineer so I research everything like a project for work. I compare everything - cost, reviews, cost over lifetime, fuel economy, ease of maintenance, etc. So, I'm not impressed by a flashy outward appearance, but the inner workings and solid framework. A long term reputation and years of customer reviews impress me more. I was more impressed after my purchase by the reviews from the installers and technicians. They were impressed and commented on the new upgrades and changes from previous models. It seems Generac listens to the customers and installers to correct issues, problems and sometimes, just little nagging items. All in all, I was happy before I purchased my generator. Now, I am overjoyed after hearing feedback from everyone from the electricians to the country electrical inspector on the value and abilities of this model.

Only had my 24kw for about 1 month, then after severe storms we lost power for 5 days straight. Having a newborn/toddler was one of the main reasons I chose to install one but honestly is a great choice for everyone! Our lives never skipped a beat, it ran our whole house seamlessly including all appliances, our 5 ton a/c unit and even our heated inground pool! Other than the destruction from mother nature you would never have known we were without power and could go on as if nothing happened. Thank you Generac!!!

Had a Guardian 24kw generator installed about 1 yr ago by Ambrose Electric. Installation went very smoothly and has a very acceptable appearance. Initial oil change and service check is simple. Everything is easy to get at. We have had two short term power outages since installation and everything works pefectly. Our house is total electric and we have no problem living normally during outages. Well pump, water heater, clothes dryer and electric heat all operate normally although we do take care to limit burner/oven usage on the stove if the electric heat is in use, for example. The Generac handles it all with no strain. My one complaint is with the exercise program. It runs for only five minutes under no load. This causes moisture in the air to condense into the oil. Particularly in the winter. I spent 50 yrs as a Diesel and heavy equipment mechanic. Moisture in oil is never acceptable, despite what Generac claims. Originally set to exercise weekly I changed it to monthly and on those days I trip the main breaker to put the unit under load for 30-60 minutes. Unit is exercised and the oil stays moisture free. All-in-all an excellent unit and it is great not having to get up in the middle of a winter night, or any other time, and go hook up a portable generator.

The generator is nicely designed and is quiet. Operation is automatic with 7 second delay. With locks to keep the unit access secure and bolted to a concrete base keeps the unit safe and stable. Totally happy with this product and would recommend to anyone looking to install a whole house generator.

I am writing out of complete ignorance since we have not had the opportunity to use our generator yet. But the fact that we are both in our mid 80's, and out in the country, we thought it prudent to have this unit installed. We have faith in the product and our dealer from "All Install",so when we need it - it will keep us safe. Barry Miller, Rixeyville, VA

I just finished installation of a Generac 22kw 70422 unit to replace a 10 year old Generac 20kw model. The installation went very well as I was using my existing ATS. The wiring diagrams could of been a little clearer identifying where the wires needed to land and how many the unit actually needed to function properly. Four of the five terminals were clearly identified the 5th wire required a little research. It would have been helpful if I would have know the gas line from the unit was 3/4 inch rather than the 1/2 inch used by the 20kw model. The WiFi instructions were as little cloudy but after the calling the helpline I received outstanding service. Hopefully this unit will last for many years! I have installed about 6 of these units over the last 10 years and the 20kw model I just replaced is the only one I have had issues with. I would strongly recommend Generac to others seeking standby power options!

The most prominent feature of our 24kw generator is the peace of mind that it carries. Had ours installed by Mr. Watts Electrical following the recent cold snap here in North Texas. They had units in stock where other installers were 4-7 months out. The installation was done by one of Mr. Watts Electrical team of professional plumbers and electricians. Both my wife and I are pleased and highly recommend this product.

Dealer did an excellent job installing generator, linking together two transfer switches due to two CB panels, and balancing CB panel loads. Had to dig two trenches due to location of LP tank and service entrance with respect to generator location. Connections and startup were normal. Only problems encountered were delay in obtaining generator delivery from factory and weather due to hurricanes Harvey and Irma. Generator picked up whole house load with no problem. Ran weekly self test today right on schedule.

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.
