"I had a next day rush job to do and Tranmer Electric was there bright and early and got the job done. Very responsive and quality work. Also left the worksite broom clean. I would definitely recommend them and would use them again."

"This was by far the best contractor experience I’ve had in many years. Rob is friendly, knowledgeable and professional. He was able to work within my budget and kept me informed during every stage of the process. My generator was ordered and installed in only one week, which was also very impressive. I would highly recommend Buckley & Son Electrical Contractors."

"Lenny and his team at Limitless Electric were outstanding, professional, on time, and incredibly reliable. He resolved my solar accounting issues, added outlets, ran a Cat6 drop, and updated my Powerwall system for full-house backup. I really appreciate their clear communication and dependability, especially after dealing with other contractors who were constantly late despite doing good work. Limitless Electric is now my go-to for all future electrical projects—highly recommended!"

"Mike re-wired my basement outlets at my apartment. He figured out that all of them were wired incorrectly. Not only did he restore power to my basement outlets, he prevented an electrical fire from the previous incorrect wiring. He also installed a new bathroom fan/light combo, with Bluetooth speaker capabilities and multiple led light colors. He was efficient, fairly priced and honest. Highly recommend! Thank you again Mike!"
