The service man who arrived at my home to check my Cummins Generator could not have been more professional, courteous, and helpful. There was no doubt in my mind that he was going to make sure I understood his advice and instructions. Many many many thanks. Many many thanks.

I recently purchased a whole house generator from Colonial Electric through Costco. I had a problem with Costco getting my shop card, which was promised at the time of purchase. Without the help from Shawn Arndt I’m not sure I would have been able to obtain this card. Thankfully Shawn helped me to obtain it. He was so responsive and helpful. Thanks again Shawn.

Very disappointing experience. We scheduled an on-site visit and waited a long time for the quote. Once it was finally received and we tried to move forward, the company stopped responding entirely. We followed up several times and even contacted the owner with no response. For a company selling emergency backup power, the lack of communication was concerning.
