We like how this generator works

My wife and I wanted a home generator that would work automatically and switch on when the city grid failed us. We get this and more with this model capable of running most of our house, testing itself weekly, and monitoring its status. Furthermore, it communicates with my service advisor to quickly notify him of issues and facilitate a rapid resolution before a little problem becomes a big one.

Great product and installation

Our installer was Lawrence Levy (A Wiring Man) and he did a very professional and high-quality job. He integrated the equipment with our existing wiring and panels and fixed anticipated future problems. It was all done and tested in 1 day. He answered all our questions and is quite a personable guy. The gear all has a clean look and looks like it came with house. We installed the Generac app and it works well. I especially like the regular automatic maintenance testing. We are quite happy and now do not have to worry about highly likely multiple summer blackouts.

Stress relief!

PGE power outages are now part of living in California. We used to pack our food up in ice chests and head for a hotel. The Generac we installed lifted a huge burden off my shoulders. A minor few seconds after the outage and it kicks in automatically. Everything in the house works great and we keep going like normal. Awesome product!!!

So glad we have it

We've only had the generator for a couple of months and we already needed it once. We had a power outage in our neighborhood and within seconds the generator started up. Works great so far and we are very relieved we won't be without power during an outage. We ordered it through Esposito's Generator Solutions in Denville, NJ and the entire process from ordering to install was very smooth. They have great customer service and always respond quickly to any calls or emails. Highly recommend.

22kW is very noisy

At maximum load, the unit is very noisy. In side the house -- not problem. Outside -- big problem. We are sure I will get complaints. A fence company will be contacted with sound controlling elements to direct the noise upward to the sky, if possible. Otherwise the unit works correctly. The voltage is not at 120 VAC, but does get to 117VAC. I am not sure if that will be a problem. We can not run our electric wall oven or cloths dryer. The 5 ton AC will run with no problem, all light (all plugs), on-demand hot water heater and the two refrigerators work well. We have not tested our furnace yet. Transfer switch works quickly and power is back on in about a minute. I suggest dedicated, non-GFI for freezers and refrigerator -- when they trip, the Generac can not provide power to GFIs.

Constant maintenance issues

We have had this back up generator for about five years now. We have had scheduled maintenance done every year by Genstar and every year we have some sort of major problem. For the second time in a year and a half, all the oil has leaked out of the generator. The first time was from a pressure switch that went bad. I have not identified the source of the second leak. We’ve also had to replace the entire control panel and another electronic module. We have a severely brain damaged daughter who relies on electricity to power her ventilator, feeding pump, oxygen maker and pulmonary suction machine. We need something more reliable. We have spent about 40% of the cost of the generator in maintenance and repair repairs already in a relatively short amount of time.

Whole Home Generator

We had a major ice storm in October 2020 in Oklahoma and we were without power for 7 days. Living in the country that seem like a lifetime. We are a total electric home and that includes the well pump. No electricity means no well pump and that means no water ! We decided to invest in a Generac and we are so happy we did - it is worth all the money we paid to have peace of mind. Over the 4th of July 2022 we had a power outage for 2 1/2 house. It was 99 degrees outside but with OK humidity, it felt like 105. Your house can heat up pretty fast but as soon as the power went off, the generator started up and we back up and running with electricity. I highly recommend investing in a Generac !!!

24kW

When I was looking at a new generator for my home - I looked around and searched many reviews. Happy to say that I chose one of the best - Generac. Even with the COVID issue going, on the team from my dealer did a great job in coming out and getting the install and start up done beautifully. The unit is exactly what we had hoped for. Looks smart, easy hook up, with just the right amount of technology added in. Thanks to the sales and install team for giving me a great product at a great price.

Great product

I own a Generac commercial generator for the last eight years at my place of business lost power over a dozen times due to storms has paid for it self ten fold, very reliable starts all the time and runs for as long as we have propane gas. Than I decided to get a stand alone 22 KW for my house best thing ever just lost power due to a storm five days after we installed it....I recomend a Generac for everyone.
