Ada Tang ⭐⭐⭐⭐⭐

“have just installed air-conditioning system, solar panels and security system by John and his staff. They are great. John is helpful, very patient and always willing to explain all technical terms to me in a very simply and straight forward way. His staff are efficient, polite, professional and have not mess up my new carpet 🙂 I will definitely come back to John if I need any more related stuff in my new home.”
