How Much does a Repair cost?

Air conditioning repair costs can vary widely, depending on the fault, system type, and whether parts or refrigerant are required. In some cases, repairs can be completed on the spot with minimal time and no materials. For example, simple fixes can cost as little as $250 + GST, such as resetting controls, tightening electrical connections, replacing minor components, or resolving basic operational faults. More involved repairs, including refrigerant top-ups, leak detection, or component replacements, commonly fall in the $400–$500 + GST range, depending on access, system size, and fault complexity. When major components are involved — such as compressors, circuit boards, or ongoing refrigerant leaks — repair costs can extend into the thousands. In these situations, we take the time to walk you through the numbers and honestly weigh up whether repairing or replacing your air conditioner makes better long-term sense. Our approach is always diagnosis-first. Once the issue is identified, we explain the fault, outline expected repair costs, and let you decide how you’d like to proceed.
