Saved our sanity!

Bought this over the winter and have already lost power for three days. Generac saved our food in freezers and fridges. Last year we lost everything. Like the AP so if you are away from home you can see it if it is running. Also since we are on a well, Generac kept the water running! Lights, water, kitchen, wifi all good.

Fantastic insurance for inconvenience

At my age of 67, I am glad to finally get an install a Generac standby generator. Even if the power just goes out for a few hours, it will be much easier to put up with the inconvenience. Basically there won't be an inconvenience. I believe standby generators are worth every penny.

Poor choice on my part.

We purchased it about 2 years ago and it pretty much has failed us when the need arises during storms or other weather in climate conditions. This was bought because I have a cpap machine and need it to sleep. Also to protect the contents of our freezer and fridge.

Now we have peace of mind in a storm

We bought our Stand by Generator recently and we are delighted with our purchase. I don't have to dread dragging my walker over the extension cords in the floor when the power is off. Now we simply go on as usual after a few seconds. Thank you Generac and Mr. Allen of Allen Residential Electrical for giving us peace of mind in stormy weather.

Not working to specification.

Been over a month and I have no resolution to an Engine Speed Alarm/Fault that renders the system to not initiate automatically as designed when my power goes out. Without this key feature operating correctly I feel dissatisfied. No eta has been provided for a fix which adds to my frustration.

Does the job well!

I have had it for a year now, and of course there has not been a power outage since the installation. However I did decide to run a simulation of an outage and was very happy with the results. My only issue is the description provided on Generac's website, makes it sound like the noise level is just above the level of an air conditioner. If I had an air conditioner that loud, I would be worried!!

Peace of Mind and Reliable

Having experienced "Snowmageddon" in North Dallas a few years ago and without power backup, this new Generac whole home generator brings incredible peace of mind. It's good to know it is always there ready to take over should the power grid go down. The only reason I gave it a 4-rating is because of the delay between power failure and the generator starting. I wanted Tesla's system mainly because of its ability to take over within milliseconds of losing power unlike Generac. If power is out for more than a second, then there are several clocks that have to be reset. I've had days when the power blinked multiple times thereby requiring clock resetting each time. Very annoying. If Generac would develop a battery unit to incorporate with the generator that would bridge the gap between the grid failing and the generator taking over, then I would definitely give it a 5-star rating. That's my only complaint, and it really isn't a Generac fault since it operates as designed. I just wish the design would change a tad to eliminate the time gap.

Great Features and Reliable

It has been very reliable and we are very happy with our investment and equally happy with Genesis Electric install and assistance! If you've ever been without power for a prolonged period, you know how important it is to have a backup system, and especially important as you age for safety reasons.

Love our Generac❤️

We have been thinking about buying a Generac for years. So glad we finally did! Our neighbors had their installation done in 2018. Every time a storm caused an outage, they were completely comfortable, up and running! It has made us feel much more secure with the hurricane season coming.

Just do it

I was hesitant to purchase this at first. My wife insisted that we do. Since purchase we have had 2 major storms and the Generac has performed flawlessly. The whole valley was without power for 2 days and we were eating popcorn and watching Netflix. I will say that we can hear it running when it comes on, but it's a small price to pay for comfort.
