Not the first, wont be the last!

Our most recent purchase was a replacement unit for fhe original used unit we had for 10 years. We did not even hesitate when it came for the replacement. Our first unit was about 5 years old when we got it and it lasted another 10 years and was an absolute blessing when we needed it. So happy we installed a whole home generator shortly after we moved in!

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.

Ease of mind.

When installed we were very pleased. In the past year it was only needed for a few hours but the ease of mind is well worth it. Sound is a bit loud and weekly testing is very reliable, The wifi needs improvement when the signal is lost. It is a bit difficult to reconnect. Our installer was excellent.

Don’t Waste Your Money - Buy A Different Brand

I bought this generator and installation was attempted by a Generac “Elite” dealer and installer. Now, 3 weeks later, and after multiple attempts by the installer, IT STILL DOES NOT WORK! There are battery charging error codes and fuel delivery error codes. If it comes on during the weekly self test it shuts off after 4 minutes, the warning light turns red and it sends a warning that it won’t restart in an emergency. Don’t waste your money buying a Generac 22KW whole house standby generator. Look at other brands that actually work .

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.

Beware

Died 30 minutes into TS Helene 9/24. Even with all the $$ and "certified" service, a wrong oil filter was used causing an oil blowout through air cleaner. 24 hour support a joke, kept referring to companies inside the storm zone (they were wiped out). Took six month to repair after reaching out to a very large generator company 2 hours away. Oh and mobile kept reporting everything was ok (generator was off) for those 6 months.

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.

Power in mind

Our Generac was installed new, at the end of February and we are really excited to have it. Although the power has not failed as of yet we feel more secure having the backup/emergency power. I have been disabled for 10 years now and having to lug around a portable generator only to run a fridge and furnace fan was getting very hard to manage for me. Now I can sleep a lot better knowing all that and more will be working as it should when commercial power is not available.

Excellent Great installation, look great Very impressed with the Installers effort to evaluate our power requirements He contacted the local utility company and found out our average and peak power utilization from the past two years and installed a system that will totally support the whole house

Seamless

I bought this magnificently engeneered machine in February this year. My neighbours and friends made fun of me, saying that I didn't need a generator for the entire house. The thing is, I work from home online. No power = no revenue. I own five pets. No power = no drinking water because I have a surface well. No power = no drinking water (for humans too), no flushing, no showering nor bathing. Since the installation a month ago, we have had five power outages which would have cost me five days of work. The transition to the generator power is absolutely seamless, in fact, I was not aware of any of those outages, happily working away in my home office...I learned through the neighbours' complaining about the length of time it took to reestablish power. On a couple of occasions, I could hear a 'lawnmower' going and thought to myself 'who on earth would mow the lawn under three feet of snow! Only then did I realize that the lawnmower noise was actually the generator doing its job! lol I am so glad I did not listen to my neighbours and friends! I rated four stars only because there was a set back with the installation date.
