CDS Energy Electrical Services does electrical work and heat pumps. The company's website says it provides electrical and energy solutions throughout Maine, from homes and businesses to industrial facilities. A recent customer said CDS installed their new heat pump, and that Dereck explained the unit's benefits and how to operate it and kept the site clean. A recent customer said Dereck quickly diagnosed a heat pump problem and had it fixed. A recent reviewer said CDS Energy and Dereck updated all of their outlets, switches and breakers and added a few new fixtures, and that he cleans up after each project. A 2026 customer in Madison said Dereck serviced their heat pump, changed exterior lights and a bathroom exhaust fan, installed a generator hookup, and later had CDS wire their seasonal camp from the pole installation onward, keeping to the schedule and the estimate. The Maine electrician license MS60023000, held by DERECK N. SHAW, is active on the state registry.
Dereck was incredibly knowledgeable and professional. We were having trouble with our heat pump, and he quickly diagnosed the issue and had it fixed in no time. He explained everything clearly, was courteous throughout the visit, and made the whole process stress-free. We really appreciate his expertise and highly recommend him!
I can’t recommend Dereck Shaw and CDS Energy Services highly enough. Dereck was professional, knowledgeable, and incredibly responsive from start to finish. The quality of the workmanship was outstanding, and he took the time to explain everything clearly while making sure the job was done safely and correctly. He showed up when he said he would, kept the work area clean, and completed the project on schedule. If you’re looking for a trustworthy electrician who delivers exceptional service and quality, CDS Energy Electrical Services is the company to call. I’ll definitely be using them again for future electrical projects!
Very professional and timely. Communication and price were great. Highly recommend Dereck and CDS for any job.
