No more 20 below nights pulling a pullcord

Installed April 2017 right next to service entrance. Looks very nice and reassuring. My wife and I feel a weight lifted. No more 20 below January nights yanking on a pull-cord with stiff oil in the pan. First power outage came this June, in 45 seconds we had power and there was no hint when the power came back and the generator turned off. We have the 22kw standalone. One thing to remember. The generator comes set for a delay start up time of only 5 seconds. Every little power hit or sag will have the generator starting and stopping. Only your approved service installer can change that time. We had ours changed to 30 seconds. No only real power failures turn the generator on. Comes on every Saturday morning for 10 minutes. Connected to its own 500 gallon propane tank. Worth every cent at 73 years old. Save a lot of money the closer to your service entrance you can get. Buy the biggest generator you can afford, I suggest the biggest.

Access via remote updates should be standard!

I can only respond to the monthly start-ups and the comfort of having it in place for outages. I have not needed for any amount of time yet and can only hope it stands up to its first test under fire ;) The remote access / smart phone option should be standard equipment...its 2017..someelse will beat you to the punch and steal some of your business, you need to stay on top! Send one to my house and I'll be sure to spread the word :) RMS

Best Security

My wife and I are in our mid seventies, and it's a nice feeling knowing we won't be without what we need when we need it. This is here for us, and we can't ask for anything more than that. One of the best investments we made for ourselves. Thank you Generac.

Runs quieter and has great App features.

We bought this 24KW four months ago and was only able to get it installed a month ago. So far we're very pleased with it. We bought a 22KW Generac 20 years ago and got a lot of usage out of it in south Louisiana. Back then it was referred to as a "whole house generator" but we soon learned that didn't mean you could run "everything" in the house on it. It running under a load because of a power outage and my wife was running the clothes washer, dryer, microwave, the electric oven and all the lights at the same time and it handling the load just fine until our 3.5 ton AC kicked on and it started to bog down badly. Lesson learned!! We have only used this one in the exercise schedule and not under a load yet. It is quieter than our old one though. Be sure to get the App for it if you want a more detailed status of it and setup an exercise schedule.

Nice product

I purchased this 22 W backup generator about a month and a half ago and hope it works when I really need it. The installation went well and on time however I was not given any instructions on how the generator works or what I should do other than calling them if there's a problem, I was given no information on how to set up the monitoring app on my cell phone at all so I have it on and I guess it's OK but that's about it.

50/50 feelings

I wish I had better things to say but I feel the company that installed the unit did a poor job the unit leaks oil and when I told them about it on the 1st maintenance visit, they wanted charge me extra this was part of the installation and has been leaking ever since . Other folks may have a better experience with this brand I think it was just the company that has installed mine .

Generac's fine. Stay away from ACS Home Svcs Tampa

I am very satisfied with the unit itself, however I would never recommend the company used for the installation. They were the worst, most disreputable company ever (ACS Home Services of Tampa Florida) It took us 7 months to get it installed after signing the contract, and they demanded payment in full before they would even deliver the unit to our house after a $1,500.00 deposit at signing.

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.

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.

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.
