"I highly recommend First Class Electric. I called this morning and by 10 am Joey the technician was calling me confirming he was on his way. The operator who made the appointment was very friendly and helpful. The technician Joey was very knowledgeable and friendly. He is an asset to your company! He understood what needed to be done and explained his plan. He made sure I was satisfied and answered every question. I will definitely use this company again but I want Joey to be the technician. Thank You!!!"

"We had an excellent experience with this electrician at our 120,000 sq ft office building. He came out to perform repairs and upgrades on our electrical systems and delivered truly professional, high‑quality workmanship from start to finish. His knowledge, attention to detail, and clear communication made the entire process smooth and efficient. It’s not easy finding someone who can handle large‑scale commercial electrical work with this level of skill and reliability. He showed up on time, worked safely, and made sure everything was done correctly the first time. I highly recommend him for any commercial or residential electrical needs. Outstanding service and professionalism"

"Chris at ARS Electric was both knowledgeable and friendly. He and his coworker were able to come for my small bathroom exhaust fan installation job the day after I inquired on Home Advisor. Accessibility to contractors these days is never that fast. I highly recommend the services if ARS Electric."
