A circuit breaker that keeps tripping is usually caused by one of four things — an overloaded circuit, a short circuit, a ground fault, or a faulty breaker. Overloaded circuits are the most common and often fixable by redistributing appliances. Short circuits and ground faults are dangerous and need an electrician immediately. In Brisbane, we see this constantly in older Redlands homes with 30-year-old wiring that wasn’t designed for modern loads like air conditioners, EV chargers, and heat pump hot water systems. Typical Brisbane costs: $150–$600 for most fixes, $1,200–$2,500 for switchboard upgrades.

In 2026, a typical inverter split system costs roughly $0.20–$0.75 an hour to run in Brisbane — about $0.23/hr for a small bedroom unit through to $0.73/hr for a large open-plan system running flat out. Because modern inverters ease off once the room hits temperature, your real-world cost is usually 40–60% lower than that. For most Redlands homes, expect around $30–$90 a month per system across summer.
