Love This Generator!!
By Michael W.
Grand Bay, Alabama
Purchased 05/23/2013 |
Review Posted 10/09/2017
I've been very happy with my generator. I've been through numerous storms, the latest being Hurricane Nate, which was pretty close to a direct hit. My EG came up in 17 seconds and ran for over 24 hours until my power was restored. I bought and installed this unit myself, but I did sign up for a service contract with a local company to maintain it for me. The big benefit there was a modification came out on the gas valve I wouldn't have known about without the service guys.

Pros:
I'd Buy It Again, Easy To Use, Reliable
Power went out morning after installation.
By Max C.
Edgewood, Washington
Review Posted 10/30/2015
My wife has Alzheimer's, so we moved in with our daughter and son in law and two grandchildren.
We paid for a remodel which included a complete electrical up-grade to code, new meter, new switch box, rewiring outdated electrical, and adding the whole house generator using an upgraded natural gas line and meter.
The work took nearly three months. The morning after we moved in, the same morning after the completed install of the generator, the city power went out.
Since then, we have lost power several times, the longest was for more than 24 hours.
While the neighborhood went without, we had power, refrigeration, and all our other utilities including heat and hot water.
Thank you.

The Talking Generator
By Charles C.
Steele, Missouri
Purchased 01/29/2014 |
Review Posted 04/20/2015
I purchased this Generac generator in February 2014 and it was installed in March of the same year by myself the owner. The installation instructions were very easy to follow, and I have not had any problems with this generator. Power Equipment Direct was very helpful in acquiring this generator, and it was shipped right on time as they stated that it would be.
I found this generator to be exactly as described and it has showed to service my house very well. I am pleased with the purchase of this generator and the service of this company and would recommend this company and generator to anyone that is thinking about purchasing a whole house generator.

Satisfaction
By Ben B.
Okeechobee, Florida
Purchased 08/02/2014 |
Review Posted 12/04/2014
While it took some time to get the suppliers (gas mechanic and delivery and the electrical company) to do their part, everything seems perfect. It has exercised at the proper time for three weeks.
The smart switch was checked and promptly switched to service from the generator instead of incoming service. No hurricanes this year and no outages for other reasons but it did start and run for a couple of minutes once then shut down.
Electrician said it noticed and anticipated low incoming voltage and prepared to pick up the load, then shut down when line voltage returned to normal. It seems to do all it should and I am pleased.

You Should Have Told Me!!
By John M.
Jena, Louisiana
Purchased 06/18/2014 |
Review Posted 10/31/2014
While I am pleased with my 20kW Generac system, I am very disappointed with the vendor who should have told me: Hey, wait only one more month and we can sell you a 22kW generac air cooled system for only about $500.00 more.
Instead, I now have a perfectly good generator, but it is 10% less capacity than one I could have bought just one month later.
I have been informed that there is presently no way to convert my 20kW to a 22kW, even though the motor is the same size. Apparently the six (6) pound difference in weight between the 20 and 22 kW unit is in the alternator winding.
Shame on you for not telling me in time.

The Generac 20kW generator has been their best selling unit for years and they have re-worked it to make it a 22kW unit. Generac introduced these units to us and we were not able to sell them until the 20kW models were sold out.
There are very few changes to the 22kW unit and it only provides 9 more amps. Typically this will not come into play since it is not even enough to power a single 15-amp circuit. Generac simply was the first to come out with a 22kW Air-Cooled model and honestly for most applications it's overkill.

Just finished the installation. Nice looking unit. Has only been run to test installation and first exercise run.
Excellent buying experience. Good price, quick shipment. Driver even delivered the generator to the installation site at the rear of the house.

I am so pleased with this generator!
By Gladene M.
Nacogdoches, Texas
Purchased 08/07/2014 |
Review Posted 10/02/2014
I live in an area that the electricity seems to go off fairly often. I live alone, and am not able to crank a small generator. So, I decided to get the standby one. This is the first day that my generator has needed to come on, and it did - just like a champ!
My electricity was off about an hour early this morning. Then at noon today was the time for the weekly test and the clocks didn't even blink! It is a wonderful thing to not have to worry about the electricity anymore! I just appreciate this Generac so much!
