What Affects the Cost
Fault type. A blocked condensate drain or dirty filter is a service call. A failed compressor or PCB board replacement is a major repair.
Unit type. Split systems are easier to access and diagnose. Ducted systems involve roof space work, longer refrigerant lines, and more complex controls.
Parts availability. Common brands (Daikin, Mitsubishi, Fujitsu) have readily available parts. Discontinued models or obscure brands may require special ordering with longer wait times.
Refrigerant type. Units running R22 (pre-2010) cannot be legally regassed. If refrigerant work is needed, the entire unit must be
replaced with a new system; a new split system costs $1,500–$10,200 per system supplied and installed.
Unit age. Older units are more likely to need multiple component replacements. Parts for units over 15 years old become increasingly scarce.
After-hours callout. Emergency, weekend, and public holiday repairs carry premium rates on top of the standard diagnostic fee.
Warranty status. Check your warranty first. Standard manufacturer warranties run 5 years, with some brands offering 7 to 10 years on compressors. Warranty repairs cost nothing beyond the callout.
A routine service or minor fix like a capacitor swap on an accessible split system sits toward $150. A compressor replacement on a ducted system requiring crane access or major component work pushes toward $1,600.
After-hours and weekend callouts carry significant premiums. If your unit has stopped cooling but is not leaking water or making burning smells, scheduling a business-hours appointment saves money. If you smell burning or see sparking, turn off the unit at the isolator and the circuit breaker immediately.
City and Regional Price Comparison
Repair costs vary across Australian capitals, driven by climate intensity, trade labour pool size, and seasonal demand patterns.
City-level differences. Sydney pricing serves as the national baseline at $150–$1,600 per job. Melbourne tracks close to Sydney rates, with year-round demand from units used for both heating and cooling. Brisbane's extended cooling season means units work harder and fail more often, but a larger aircon trade pool keeps rates competitive. In Perth and Adelaide, smaller trade pools affect availability, while extreme summer heat drives peak-season demand that can influence repair quotes.
Seasonal variation. Aircon repair is highly seasonal. Wait times blow out in January and February across all cities, particularly in Perth and Adelaide where consecutive 40°C+ days cause mass breakdowns. Booking a pre-summer service in autumn or early spring avoids peak-season wait times and emergency premiums.
How We Calculate
Estimates are based on current licenced air conditioning technician rates in each capital, adjusted for regional labour costs, typical unit age, and common system types. All figures include GST. Prices reflect standard residential repairs on split and ducted systems. Commercial systems, multi-unit installations, or heritage-listed properties with access restrictions may fall outside these ranges.
