"I can’t recommend Botelho and Sons Electric highly enough. From start to finish, the experience was outstanding. They were punctual, neat, and completely reliable, showing up exactly when they said they would and keeping the work area clean and organized throughout the entire project. I had a 200-amp panel upgrade, lines run to a pool & hot tub, copper wire installed for the pool and the connection for our generator - everything was done to code, with obvious skill and attention to detail. Out of 6 electricians I got quotes from, Ryan offered the best price without cutting any corners. On top of that, both he and his employee were incredibly knowledgeable and professional. Bonus points for being amazing with my 130 lb Cane Corso, who is usually suspicious of strangers. It was clear they were comfortable around dogs and respectful of my space, which made the whole process that much smoother. If you want high-quality work from someone you can trust, I wouldn’t look any further!"

"Everyone we dealt with was friendly, responsive and knowledgeable. From our initial call to explore a generator through purchasing and installation, everyone at COX demonstrated exceptional and timely customer service. Their experienced team of technicians were there on time when they said theyâ d be there. They provided timely notifications and clearly communicated throughout every step of the installation process. We were impressed with their work ethic and the results."

"I highly recommend Ben @ ABN for your electrician needs. I hired ABN to replace outdated two-prong outlets with three-prong GFCIs, and install a completely new outlet in my bathroom, and they did an incredible job in no time. Their professionalism, skill, prices, and good attitude were excellent. I will be hiring ABN for all of my future projects too. Thanks!"
