good features works as advertised

a little cumbersome to setup and program but once complete everything works as it is suppose to . just got it installed and haven;t had to use it yet. looks to me that one needs to make sure to size it wright . most people do not realize the amount of power the average home can consume. and a load management system or load shedding system should be considered . Also something to consider is the price of installation, i/e gas line and electrical connections,

LOVE MY GENERAC!

I wish I had purchased my generator years ago! We had 2 hurricanes in October of last year, one of which we were without power for 6 days. My generator was a life saver! It has already paid for itself with that first storm! I would recommend Generac to everybody! Especially if you live in hurricane areas. You won't regret it, I promise.

A must have!

I purchased a 20 kw generator with the Nexus Smart switch. I live on the water on Long Island's south shore. I was hit with Frankenstorm Sandy and my generator was swamped with salt water. when the storm ended I doused it with fresh water and WD40. I had it turned off as the storm hit. I removed the spark plugs and pumped out the water. I also changed the oil. I charged the battery and to my surprise I was able to start the generator. With fire extinguisher in hand I energized it and it was putting out electricity. I had it running for 13 days straight because I knew it would not start again. The starter was ruined. It ran like a top and never burned a drop of oil. Thanks Generac you made a great machine!

Reliable power, just what I was looking for ...

Living in post-Katrina New Orleans has been a trying experience at times. Power outages were frequent and tended to last long. Even worse was the aftermath of Hurricane Gustav when we lost power for over 4 days. Last year in preparation for hurricane season my wife and I decided to invest in a Generac generator. We'd done research and were convinced a company that specializes in generators probably had more going for it. Having an engine designed for the purpose was very compelling. We're very satisfied. We've had several outages from brief to overnight and that feeling of being entirely safe, cool (summer time), with everything we could want or need at our disposal was very reassuring. We were also very impressed with how quiet the generator is. When running we can only detect it if we're in the room right next to it. Upstairs, in our living room or office we're completely unaware it is running. I can't say enough good things about Generac or our dealer. Quality product, quality service, and super reliability all the way around.

Peace of Mind

We have springs under our basement floor and a sump pump needs to run at least every hour or our basement starts filling with water. A generator is a necessity. The one we used to have needed to be started manually. The new generac is automatic, the power goes off and in a few seconds we have power again. Great in the middle of a cold night or when we are gone. True peace of mind.

Love this machine!!!!

My family was tired of being without power for days at a time. Twenty one days just in 2012. Considered other brands, but bottom line is you can't beat the Generac repution. They have the top machines in the business. You may find cheaper units by other competitors, but you get what you pay for!

Essential Equipment

Get this generator! Here in northern New Jersey power outages are a fact of life. Some last minutes, others last WEEKS. Our Generac kicks in automatically after only a few seconds and powers the entire house. We have our heating, cooling, lights, communications, and even our entertainment. But what is truly priceless is the peace of mind we enjoy knowing we have reliable and always-ready backup power. Generac is the king of generators for one reason - they're the best!

Love It

I just had my generator installed and really like it. It looks good(about the same color as my house), comes on when the main power goes out, runs the whole house and everything about it is automatic. I also have the MobileLink and it is a great feature to have since I am out of town a lot and for a couple of weeks at a time.

The leading product for peace of mind during power outages

How great to have a top notch product installed by a top notch Generac dealer. Let's face it, storms and power outages threaten to become more frequent and more intense. The peace of mind is so very worth it. It's the only generator you see in my neighbourhood.

Does what it's supposed to do, seamlessly

We were extremely happy with the selection, price, installation and service provided by our local Generac supplier. Unfortunately, the unit did have a faulty engine which needed to be replaced after 4 months. However, the response from both our supplier and Generac was faultless, the new engine was installed without fuss and the unit has worked for the year since without any further problems. The unit has only actually had to operate during a power outage once so far, but did it's job when needed. Overall, I would recommend this unit to prospective purchasers, especially through the supplier we used. Choosing the right supplier/installer is a key factor.
