    It was a pleasant experience from go to whoa.

    Arran listened to all our requirements and concerns and came up with a suggested system that fitted our needs.

    His team arrived punctually on the day and installed it within the day,

    No problems or hassles, even cleaned up all the dust, packaging, and took the old system and rubbish with them.

    The new system was commissioned and working better than we had hoped for.

    Many thanks to Arran and his team for a job well done.

    Great experience from the start! Stephen went above and beyond for us, giving excellent and honest advice. He gave us extremely competitive quotes and his team was professional on the day of installation. You will not regret using Maxim Air Conditioning! Will definitely use them again in the future.

    The guys from Maxim were really great. Our installation was a bit complicated and Arran spent a lot of time with us scoping the job to make sure everything was covered. He then presented us with options to make sure we got the best solution possible. On the day, the team of Stephen, Victor, Matt, Sam and Hamid did a really professional job. They were careful, the standard of work was excellent and they did a great job cleaning up afterwards. I would happily recommend Maxim to anyone looking for a quality air conditioning team.

    Great experience from start to finish. Arran was very professional over the phone and very informative about the products available and the whole installation process. He also made a follow up call to check on the installation and service provided. The 2 installation guys were also very friendly and professional and did a great job with the our Mitsubishi reverse split system install and even fixed some ducting on our existing ducted system. Best service we've had so far from any company during our renovations. Thanks guys!

    Just had a ducted system and a single unit installed by Maxim. The "whole journey" was an exceptional experience! - very approachable, competitive and reasonable pricing, accommodating to installation date, friendly staff including the owners, who are down to earth people.

    No need to look elsewhere!
