This is very important to me since I traverse from floor to floor in an elevator. My hat is off to CMI for Dale who runs a tight ship, Christy for coordinating all communications and timetables, and especially to Xavier Williams who knows the inner workings of my Generac like the back of his hand!

This is a larger electrical company. They used our house as an employee training center and we had…read morea few unexperienced new electricians doing the work with one experienced professional electrician supervising. So they use the better employees for commercial jobs and train their new employees on residential jobs. I will not get into the details of their work, but would recommend if you decide to use this company that you explain to them that you do not want your house used to train their new employees. For the premium price we paid we did not get premium service.

They installed 10 outlets from the breaker panel in my basement and one over my fireplace. They were in and out in no time you wouldn't even know they was there. they left the place so clean and the price was great. I plan on using them again to install a sub-panel.

They were were prompt, courteous (taking off their shoes when they noticed our rug was new), fans friendly. We discussed in detail what we wanted. They provided options and explained what was loss and what wasn't. They completed the work quickly and quietly. Would hire again.

Won't service Generac generators that they didn't originally install! Really?!?!…read more I found CDS on the Generac website as one of the local authorized service providers for Generac. We have a large whole-house Generac unit for the house we recently bought and I called CDS to set up the annual maintenance. However, from the very first words out of her mouth, the rude, snappy, and curt receptionist who took my call lost the business for CDS. Her negative tone and apparent unwillingness to do the basics of her job continued to decline over the next five minutes of that call. I gave her the model and serial number of our unit and she said it was too old to look up. I told her the date on the unit was 2006, and she said our 2006 generator was likely too old to be serviced...Ha!!...and her tone further worsened when she asked if CDS had installed it originally. We bought the house last year--how would I know who installed it nearly 20 years ago? What service company worth its salt would refuse to work on their designated brand just because they had not done the original install. In sharp contrast to this disappointing call, I then called A-to-Z Contracting and provided the same model and serial number, they looked it up in an instant and told me what a great unit I had. A-to-Z scheduled a service call right then at a cost for the annual full service that was less than CDS. I Wonder if the owner of CDS knows how much business this salty employee is costing them? Recommend you stay away from CDS--what other areas are they cutting corners on if their first line interface with the customer is such a poorly managed employee?

Our experience has been disappointing. We called CDS because we had a longstanding problem with…read moreovercrank faults in our whole-house generator. The service in March fixed the problem temporarily, but very soon thereafter we again got the same overcrank fault. They came again in May and this time they identified the underlying problem. (They recommended someone else to do the repair, which is now done.) To our surprise, they have insisted on charging us full price for both service calls even though it seems likely that the problem existed and they missed it the first time.

I recently had a generator installed by Colonial Generators through the Costco program, and I'm…read morevery pleased with the overall experience. Initially, I had a few concerns during the sales process, but the director, John, personally stepped in and went above and beyond to ensure everything was addressed and that I felt confident moving forward. His dedication to customer satisfaction really stood out. The installation process was thorough and well-coordinated, even though it ended up taking an extra day. The team remained professional and committed throughout, ensuring everything was completed to the highest standard. They also handled all the necessary permits, making the process seamless from start to finish. I'm very happy with the end result and highly recommend Colonial Generators for their excellent customer service and quality work. I have not yet had to use the generator (haven't had any power losses) or use their warranty service, so I can't comment on those.
