Dan came out to quote and gave off a good vibe from the very start. He was very informative took his time and answered all the questions I had to help me make the right choice about the units I needed. He kept in contact with me throughout and even came by the site to ensure things were runing smoothly. The guys were very polite and worked with minimal disruption. Both cooling and heating units work well and I would highly recommend Australian Climate Systems not only for their products but also for their customer service
