Installation and operation of Guardian +200A was fast and easy to test. The redesigned 22KW unit looks great and code panel is easy to understand. The test startup after fuel line attached was instant start after 2 cranks. 2nd test after install of electric switch over was instant start and had electric flowing in 6 seconds. This will make our home easier to maintain now without worries of weather or Electric company problems delivering needed power. We now can take vacations and not have to worry about electric outages.

Overall I am VERY satisfied with my Generac. The things I see in need of improvement are better communication. Be easier to reach. You guys advertise you try to leave the landscape as close to as you found it however they did a poor job of covering my ditch and they left a hole in the concrete. They were to send a crew to finish but I got tired of waiting. I got someone to do it my self. I also got someone my self to get the landscape back on order. I STILL highly recommend getting a Generac.

For unknown reasons we've recently been experiencing more frequent power outages in the Ohio region than we have in the past 20 years. In June we went 4 days in 95 deg. temperatures without power. On day 3 we decided as soon as possible we'd be getting a standby generator. Close friends who have Generac Generators highly recommended the units and Riverside Electric, our installers. 3 Days after Thanksgiving, the install was completed by our Dealer. 4 Days after Thanksgiving we had a 1 hour power outage with a house full of family guest staying after the holidays. No one, including my wife and I knew we'd experienced an outage until we woke to find text messages from our power company and Mobile Link that our generator had been keeping us fully powered throughout the outage. We didn't even hear the generator run! We are thoroughly impressed with the quality and responsiveness of our new generator. Can't recommend it enough. Unfortunately, I suspect we are going to need it even more in the coming future.

We installed a 15Kw unit 13 years ago, virtually trouble free operation. We decided to upgrade to a 22Kw unit due to the age of the first installation. The new one is quieter, the power is more pure and we now have load control for managing the HVAC system. The WiFi monitoring is great! Smooth replacement installation.

With young children in my house, I don't want to worry about keeping them warm in winter or cool in summer. With everything powered these days, including cell phones, that we use exclusively for communication... I can't afford to be without power. Food in refrigerator and freezers will not spoil. Life will go on "normally" in the house when the power goes out. Having a whole house generator installed, lets me not worry about a power outage anymore. So glad that Generac makes residential generators... it will last.

We had the 22kW unit installed almost a year ago after suffering through 3 days of 95+ degree heat without power. The installation went very smooth. The electrical contractors were knowledgeable and easy to work with. During the past year the generator has performed it's weekly exercise cycle without a hitch. This morning we had our first power failure since the installation. The generator automatically kicked on and we had power after 15 seconds or so. Utility power was restored 2 hours later and the generator performed perfectly during the outage. The only issue we had was when the A/C kicked on the lights started pulsing and the generator itself was pulsing. I sent a text to our contractor and in less than 20 minutes the tech was here to adjust the NG flow/pressure. Great service! I highly recommend this product for anyone who wants peace of mind that comes with knowledge that you will have a continuous power supply when bad weather hits.

A local IASD checked out and started up our new 22kW generator with transfer switch on Tuesday afternoon. Everything worked perfectly including the test of the Automatic transfer. On Friday Afternoon of the same week, we had an abrupt power outage. About 10 sec later the transfer switch operated and picked up the house load. The unit operated perfectly for about an hour. Afterwards, while in the garage adjacent to the generator, I realized I did not hear the hum of the unit. The unit had transferred back to the utility power and shutdown, without me noticing it. Great transfer!! Yes I would recommend this unit!

I just had a 22kW whole House Generator installed by TADCO Electrical Contractors. Tim Davis did an outstanding job of sizing my requirements, installing the generator, and demonstrating its use after installation. A turn key operation all the way. I highly recommend TADCO if you are interested in a Generac in Central Florida.

I bought this product about 10 years ago after a particularly severe storm knocked out power for two weeks in my area. Since then, in the thousands of hours when I did not need it, it seemed to work perfectly. During the three periods when I did needed it, it did not work at all. During one storm, with a 10 day power outage, I was able to remove the oil pressure sensor and put in a plug and I was able to get the machine going and it worked OK. Without someone making that suggestion, I would've been out of luck. Service was impossible during that period.without me jerry-rigging a repair in a snowstorm. Service in my area is very difficult, delay of two weeks defeats the purpose of the generator completely. I would not buy this generator again.

We had it installed on Jan 20, 2021...and of course, we haven't had an outage yet. Every Monday at Noon, it exercise's itself and I noticed it didn't really start on the first try, it stumbled. On the second try it would start. I contacted my dealer and they checked it out to find that the fuel pin gasket was twisted and the fuel regulator/diaphragm unit needed to be replaced. They did it on the spot and its been working fine ever since. Must have been a factory issue. Was very happy with the dealers response.
