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. Clay is the best electrician I have ever met and highly recommend him to do the install. Quality work and cleaned up the work area very well. I am totally pleased with the job.

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.
