They did a top-notch job installing our air con—super professional, efficient, and made the whole process really easy. We really appreciated how they didn’t just finish the job and leave; they made sure everything was working perfectly and that we were all sorted before they wrapped up, as well as after the installation. It’s rare to find such great service these days, but these guys nailed it. Highly recommend! Alex Pazman2025-02-24Trustindex verifies that the original source of the review is Google.

Their service, punctuality and install quality was top tier. These guys are experts in what they do. They were hired to clean existing split systems and install a new ducted system. I highly recommend them if you're looking for anything air-condition related. Taggart Veloso2025-02-05Trustindex verifies that the original source of the review is Google. Mick and his team are absolute legends! Made a phone inquiry at 10 in the morning, and by mid afternoon the same day, they were at our front doorstep to sort out our air conditioner situation. Mick over the phone was friendly and definitely a professional by already suggesting possible solutions for the situation which turned out to be spot on when his team arrived and actually fixed the problem. We absolutely recommend Mick and his company GAM Air Conditioning Installation & Repair Service for all your cooling, heating, maintenance and/or repair needs! These guys are 100% as advertised! We will be returning customers for sure!
