Hi Wade, I am very happy with the job done by your installer, Louis and his assistant, Dave. Equally very happy with your electrician, Robbie and his assistant. Their work is highly commendable. Your company exudes professionalism and efficiency to a high degree in terms of coming on the appointed date and time, installing 2 air conditioners, checking on the wiring of the 4 other air conditioners and finishing the work in just a day. This is the second time I hired your services - Firstly my home and secondly, my son's home. In both cases you have met and exceeded our expectations. All the best!

The entire ACG team are brilliant in every aspect of customer service experience. Ease of inquiries, friendly and responsive online response and phone calls. The team of Ibrahim and Jake accompanied by their boss Wade came to my home this afternoon to ensure they can complete the last job for the day. Despite running behind schedule, the guys were courteous, hard working and takes great pride in their quality workmanship and respectful of customer's home. Highly recommended and trusted company. Thank you for a positive experience.

Last year The Children’s Hospital at Westmead cared for 84,606 sick children and their families. Their family-focused multi-disciplinary teams supported 828,545 appointments through the outpatient service. They supported 32,341 inpatient admissions, 13,964 theatre procedures and 59,299 emergency department presentations.

At ACG we are enormously grateful for the ongoing effort of CHW, for the health of our children now, and into the future.
