          What They’re Saying

          I had a great experience with Morgan Trujillo! She is so helpful and understanding! You are lucky to have someone like her on your team!

          Rachel Lucero

          Generator Source has been an invaluable resource to lean on. They do good work. Shout out to Mr. Kuklinski and Mrs Trujillo for getting things done for me. The rest of the team has performed very well, also.

          Gene Otterbein

          I spent all afternoon with Morgan helping me diagnose a generator. She got a technician on the phone with me and got it running for the next day.

          Adam Todd

          Morgan is absolutely fantastic to work with! Her knowledge of generators, power solutions, and the overall process was incredibly impressive. She took the time to answer every question thoroughly and explain options clearly. As a commercial real estate broker in the Colorado Metro area, Morgan is a true resource for my clients and their needs. As a team, we are setting a proactive plan for any upcoming emergencies like the recent power outage due to the snow storm. Morgan gives reliable guidance and exceptional support.

          Lila Romano

          Highly professional. We had an urgent situation and they not only provided a solution, but they also provided a temporary solution within 24 hours so that we were up and running with minimal downtime. Tyson, Marc, and their team are awesome!

          I have worked with Morgan Trujillo for years. It is always an exceptional customer experience when Morgan assists with our power requirements. She goes above and beyond to ensure we have sized our unit correctly, both locally and on a national level. Morgan captures all the details and makes sure our guys on the ground receiving portable power are up to speed on manufacturer differences. She is a great addition to the team.

          Chuck did a great job getting the generator out of our Charlotte location. It wasn’t an easy removal as he had to deal with a hill in order to get it out. He was good to work with and made as little a footprint as possible. Project was well planned from start to finish. I would definitely recommend Generator Source for future projects. Thank you for a job well done.

          Pam Smalling

          Top notch customer service it doesn’t get better I made a call Generator Tech. Glen showed up fix the issue. Definitely high-quality customer service. Highly recommended for all generators needs.

          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.
