Rated 5 out of 5 by from Great investment We live in the foothills of Monrovia and power outages are inconvenient. Fire season is nearly year round. It is evident that Edison will be quick to shut down service at any sign of danger. To avoid "sleepless nights" we investigated full house generators and nothing came close to Generac. LT Generator was great to deal with, from the initial walk-thru and explanations right up to the final signoff. Our installation date fell right into the monsoon conditions last December and LT dealt with enormous challenges to work around them. The inside staff were great to work with and kept informed at all times. They arrived exactly when they said they would and worked past dark a couple of times. When done, the unit fired up and worked flawlessly. Said a lot to me about the professional quality of the entire crew. My next door neighbor watched the progress and was impressed. His identical unit was installed in mid-February and he had the same pleasant experience.

Rated 5 out of 5 by from Harrington Electric Asheville, NC Rick, Alan and Billy did a great job with install and cleanup. Rick reviewed the buying and install process. Install took one day. Asheville inspector approved install 48 hours after installation. I would definitely recommend Harrington Electric for Generac install and other electrician needs. 22KW was tested as part of the install process and generator set to automatically test bi-weekly based on homeowner custom times.

Rated 4 out of 5 by from Wifi set up The problem we're having is setting it up to the wifi system. You have to use your phone to activate the Generator and on the phone it ask for a code, we put in the code that was sent via email and it will not go to the next step so we can program the Generator. Our Electrician is having the same issue and is having to wait 30 minutes for technical support. There should be an easier way to program these Generators.

Rated 5 out of 5 by from I am so glad to have my Generac installed. Great relief to know when power goes off we will have cooling and no worry about food spoilage. Thanks to Mississippi Solar team Phillip, Terry, Keatzi and Corey. Phillip and Terry kept us informed on process and Keatzi and Corey did a fantastic job installing our Generac. So glad I finally made this purchase.

Rated 5 out of 5 by from This product is awesome The Generac seems to be very easy to maintain. Josh, and James did an awesome job installing it They went over the instructions as to how it would run and how to Maintain it. Everything was organized by Holly Electric and we didn't have to do a thing. The Inspection man came out while they were still here and passed the inspection. All in all a job well done no hassles and very professional . Nothing like piece of mind knowing your Genrac will kick in when power goes out, nothing for us to do but to keep enjoying life and Air Conditioner. Thank you Generac and Holly Electric, Inc.

Rated 5 out of 5 by from 24KW Generator whole house system with automatic transfer system is great! Jeff Hunter Electric is a very dependable and professional electric and generator company. I would highly recommend them for anyone thinking of having a generac generator installed or any other electrical work.

Rated 5 out of 5 by from Oustanding product I am amazed at improvements made in generators. During my career as a communicator in the Army I have used many generators of various sizes in support of communications equipment. I have used both tactical and strategic and am extremely satisfied with the product. The service, installation, training provided and hook up were professional. I am expecting years of service with the device and eagerly expect the company’s services of my generator system.
