What They’re Saying

I needed to upgrade my pecan processing plant. The equipment I need is 3 phase and I only have single phase at my location. The electric company is slow to respond and I also figured that it would not be feasible. I thought maybe a generator would work instead. I started out with an internet search and the first company that came up was Generator Source. When I brought up the website, it was very informative and had a very good selection of generators with lots of pictures. When I contacted you, you were very helpful and had several generators to choose from. I felt I really didn’t need to look anywhere else. Shipping was prompt, and the unit was just as shown in pictures.

Craig Tharp, C&C Pecan Ent

Great folks to work with. Techs are very knowledgeable and the office personnel are extremely responsive and helpful.

Beth Penzone

Great staff. Quick response, easy to understand the quote. Had my whole house generator humming within 24 hours of our first call. Highly recommend these guys. They’re the best.

Arcenious Armond

Excellent service ! The company that installed my original whole house generator went out of business. I couldn’t get another company to even respond to a phone call for continuing maintenance on my generator ! I called Generator Source and they came out the next day and serviced my generator with professional, friendly service. I absolutely will use this company again for my ongoing maintenance. Thanks Andrew and Oliver !!!
