About MaXim Air Conditioning and Mechanical Services
Around Castle Hill and the wider Hills District, MaXim Air Conditioning and Mechanical Services has built a name that people in New South Wales are happy to pass along. They handle split system installation, repairs and servicing, ducted air conditioning, and commercial work, along with multi-head and VRV/VRF systems and mechanical ventilation for both homes and businesses. The team's experience shows in the kind of jobs they take on, from fitting out an older apartment block to designing a multi-zone ducted system with temperature sensors tailored to the home.
What people appreciate comes through clearly. They turn up when they say they will and keep you in the loop, with technicians texting ahead so you know when to expect them.

More than one local has mentioned that MaXim uses their own team rather than subcontractors, which they reckon makes a real difference to the finish.
Johny and Arran come up time and again by name, Johny for prompt repairs and thorough servicing that he takes the time to explain and document, and Arran for honest advice on the right system when other installers in the area weren't interested. People have had Mitsubishi Electric and Daikin units sorted out, parts sourced for older systems, and failed air conditioners replaced in the middle of a hot Sydney summer. Free quotes and emergency call-outs are part of what they offer, and many sign on for regular servicing afterwards.
Identifying as women-owned, MaXim is the kind of air conditioning technician people call back for the next job. Call ahead to talk through your system and check availability.
