Thank you so much for your generosity and kindness today when you stopped and helped a stranded stranger with a flat tire. You saved my day and deserve absolute best wishes!
terrific job , the overall staff was great to deal with. The delivery matched exactly what was sold, exceed my expectations on a 14k standby generator and full electric panel replacement The guys were excellent. Broad knowledge of the overall space. Smart guys.
What an amazing experience. They were so professional and found a gas leak and problem with our meter. They had it taken care of immediately. Everyone was so professional and the installation couldn’t have gone any smoother than it did. I highly recommend them.
Amazing team at Generator Pro. They came out after a major snow storm and went through a bunch of tests to determine why my generator was no longer running. After the diagnostics they gave me a few potential options on next steps. We decided to move forward with Generator Pro removing our old generator and putting in a brand new one for us. They were able to complete the entire process from diagnostics to full install in less than 2 weeks (during the middle of winter no less). I have nothing but good things to say about Generator Pro. Thanks Steve, Doug, and everybody on the Generator Pro team for helping us out!
I can't say enough about the wonderful service and great people at GenPro. My requests for services on my standby generator were handled promptly, the technicians were on time, professional and didn't
