Awesome Company, Great People And A Wonderful Product
I did a lot of research prior to purchasing the 22kw Generac. I also did a lot of research on where to purchase the generator. I had options from my electrician, a turn key company where I live or the internet. I picked Electric Generators Direct because of the price, no tax, free shipping with liftgate service and the customer service has been great. They respond to emails fast and answer questions quickly. I am so pleased with our purchase. Everything is hooked up and works like a champ. We... more

22 Kw Generac Generator
We purchase this generator in January 2016 after being without power during an ice storm and later a blizzard. We went a total of 9 days. Well we had our 1st power outage today for the power company to work on lines. It worked great! We like that it comes on every Saturday. That give you assurance that we won't be in the dark the next power outage.

22kw Arrival
The generator arrived on time when stated, and in good condition. Your delivery contractor provided lift gate service, and moved the unit as far up my driveway as he could, (him pulling the pallet jack and me pushing). Could not ask for better delivery service.

I ordered the cold weather kit, and was surprised to learn upon reading the enclosed info sheet that I would have to change the 30W Organic Oil to 5W30 Full Synthetic Oil. After the unit was positioned on the pea gravel base for a few... more

22 Kw
We recently had sever flooding in the Baton Rouge area and my generator of a little more than a year old was affected. In case in would be unrepairable, I ordered another one and it is received. If it is repairable, I plan to return the new one for credit, paying the return freight. I have called the sales person (Bruce) that I dealt with several times to discuss the possible return of the unit and he has never returned my calls. It's been two weeks now!

Buy One, You Won't Regret It
We live in a very rural area of south central PA. When bad weather hits we have power outages, sometimes lasting 12 hours or longer. I purchased the 22 KW unit because it will run all of our home including the 5 ton heat pump. The unit starts right up, runs well and does not flinch if the heat pump turns on. Overall the install was relatively easy, just remember you have to have a level and drained sight to install the item, you have to run the correct size gas line to it and you have to... more
Pros: Exceeded Expectations, High Quality, I'd Buy It Again, Appearance

Bad Delivery Service
I purchased the generator (order number EGD941304) back in May. Have not had an outage since, so can not comment on the product. But , just wanted to let you know, the delivery process of the Freight company was terrible.

They called for delivery times several times and did not show up. If I order anything from you again, and you tell me you are using SAIA, I will cancel the order

Wanted to replace a liquid cooled generator with a less noisy one. The new 22 kW was the perfect replacement.

This is my 3rd Generac generator by no fault of Generac, my first two were hit by lightning, I guess I have bad luck. I would recommend Generac again!

Great Value And Quality Equipment
Bought this unit last Winter along with the transfer switch for client living in Puget Sound. They had a basement flood the season before when the power was out and their sump pump flooded the basement. This unit is easy to install, started right up, our electrician had hooked up these before so the wiring was simple and the owners are very happy. I bought the remote monitoring device and it works great - I get an email and a text every time the unit operates or runs it's maintenance cycle... more
