“Our power went out during a storm that came through during the night and we lost power. Our Generac generator didn’t startup and threw errors. I called around 9:00 am and the owner, Mason, showed up within the hour and was so great working with us. Unfortunately we have to get the motor replaced, Mason took care of calling Generac to work on getting it replaced through our warranty. We can’t say enough good things about the service we received. We will be using them now on for routine service maintenance. I HIGHLY recommend them.” – Stacy ONeal
“The installation crew was respectful and did a phenomenal job from install to clean up. The service tech came out the next day and did a complete walkthrough with me and answered every question I had. Best choice I made by using Astro Gen to service my house!!! Thank yall again.” – Roman McElfresh
“AstroGen successfully completed the installation and start up of my whole-home generator. I chose Cummins Generator. I am super pleased with the process, the workmanship and the people. I would particularly like to mention @Jose, and @Ethan who were directly responsible for the installation, both are nice and professional, and Caleb who was my main point of contact. Overall, I am satisfied with AstroGen. I have already recommended AstroGen to my neighbor who is scheduled to get his installed in a few weeks.” – Dharmesh Shah
“There are very few companies that truly deserve more than 5 stars. This is one of them. I tried to get generator quotes from several companies. And AstroGen was the only one that got back to me in a timely manner. From the first phone call they were organized, professional and transparent. Kaden came out for out house quote and walked us through options, answered all of our questions and made sure we felt comfortable. Install day was today (even after major storms last night), everything was completed on time and the owner Mason came out and looked everything over and did the final walkthrough. I could not be more appreciative of AstroGen and their team! I would highly recommend to anyone and everyone.” – Cameron Branham
