Something wrong with your air conditioning? We diagnose and repair all types of faults — from systems that won't turn on to units making strange noises.
Our F-Gas certified engineers work on all major brands including Mitsubishi, Daikin, Toshiba, Hitachi, Panasonic, and Fujitsu.
- Not cooling or heating: System running but not reaching temperature.
- Won't turn on: No power, error codes, or unresponsive controls.
- Strange noises: Rattling, buzzing, grinding, or clicking sounds.
- Water leaks: Dripping from unit, blocked drains, overflow issues.
- Bad smells: Musty odours, burning smells, stale air.

Servicing & Annual Checks
Once we've fixed your system, keep it running with regular servicing. Annual checks catch small issues before they become expensive repairs.
Most manufacturers require proof of regular servicing to honour warranty claims — we provide full documentation.
- Lower energy bills: A clean, well-tuned system uses less power.
- Fewer breakdowns: We catch problems before they fail.
- Warranty protection: Keep your manufacturer warranty valid.
- Better air quality: Clean filters mean cleaner air.

What Our Customers Say
Nici Leonard
We have used High Path Airconditioning (owner Rob Halligan) for approximately 15 years to service our air conditioning at our offices. Over the years we have found them to be very professional in both dealing with the servicing of works and delivery of the work. If we have an issue between the servicing of the units they attend site within 24 hours, often within a couple of hours of the initial phone call. Rob and his staff are very pleasant and respect that we are a working office and cause minimal disruption to our ongoing operations whilst attending site.
Marco Pasquariello
Excellent service from Rob and his team. We run a professional recording studio which relies on efficient air con around the clock. We've had issues with our original installation (from another company) which have been fixed promptly by Rob and his team. Fair pricing and great service!
