I recently had the pleasure of booking Scotty and Tain to clean my air conditioner, and I couldn't be more satisfied with their exceptional service. Their expertise and attention to detail were evident throughout the entire process. They not only efficiently cleaned the unit but also took the time to explain the maintenance steps and offer valuable tips for optimal performance. Their professionalism, punctuality, and thoroughness will make them, and the O'Brien team, my go-to choice for any electrical services in the future. Highly recommended!

FANTASTIC! From the friendly, efficient Aimee who took my call and happily answered all of my questions to the professional skills and happy faces of Liam and Henry who installed my exterior lighting requirements, I am extremely pleased - not to mention the BEST price of four quotes … by far, I highly recommend O’Brien Electrical Mount Barker SA. Thanks for an easy, enjoyable experience, I’ll be back and I’ll tell all my friends.

We contacted O'Brien Electrical and a professional and helpful receptionist promptly arranged for Scott (electrician) to attend our property. Scott was courteous and professional. He was able to find the source of our power problem, fix it and restore power and water to our house. This was all done in a professional, timely and capable manner. Many thanks to Scott and the helpful receptionist at O'Brien Electrical!
