This page covers the split system repairs we complete most across Sydney, typical costs, the faults you can check yourself first, and when a repair stops making financial sense.

Key takeaways
- Most split system faults fixed in one visit
- Typical repair cost: $180–$750
- Water leaks are usually a blocked drain — quick and affordable to fix
- Repair if under 10 years old and under half the replacement cost
Common split system repairs we handle
- Water dripping from the indoor unit — blocked condensate drain or frozen coil
- Not cooling or weak airflow — dirty filters/coils, refrigerant leak or fan fault
- Error codes on the display — sensor, board or communication faults
- Tripping the power — electrical fault, compressor issue or wiring problem
- Loud or unusual noises — fan motor bearings, loose panels or debris
- Remote or Wi-Fi control not responding — receiver, batteries or board faults
Checks worth doing before you call
- Clean the filters — restricted airflow causes half the “not cooling” calls we see
- Check the remote batteries and that the unit is in cool mode (it happens)
- Look at the isolation switch — outdoor units have their own switch that gets bumped
- Note any error code on the display — it speeds up diagnosis
- If there’s a burning smell or the unit trips power repeatedly, switch it off and call
When is a split system not worth repairing?
Split systems last 12–15 years with servicing. If yours is under 10 and the repair is under half the cost of a new unit, repair almost always wins. Replacement becomes the smarter spend when the compressor fails on an older unit, when the system uses phased-out refrigerant, or when repairs are becoming an annual habit. We quote both paths so you can decide with real numbers.

Frequently asked questions
Why is my split system leaking water?
Nine times out of ten it’s a blocked condensate drain — dust and mould clog the line and water overflows into the head unit. It’s one of the quickest, most affordable repairs we do, and a deep clean at the same time prevents recurrence.
My split system is blowing warm air — what’s wrong?
Clean the filters first. If it’s still warm, the likely causes are low refrigerant from a leak, a faulty compressor or a sensor fault. Book a diagnosis — continuing to run it low on gas can damage the compressor.
How quickly can you repair my split system?
Breakdowns are prioritised 7 days across Sydney, with same-day attendance wherever scheduling allows. Most repairs are completed in a single visit from stocked service vehicles.
Do you repair split systems in apartments?
Yes — including balcony-mounted outdoor units and strata properties. Where repairs affect common property we can provide documentation for your strata manager.
Is there a call-out fee?
Repairs start with a diagnosis visit at a fixed rate, which is confirmed when you book — no hidden charges, and the repair quote that follows is fixed-price too.
