A split system combines an indoor unit with an outdoor unit to provide heating and cooling to individual rooms or smaller areas. Trimech supplies and installs split systems for homes, with experienced technicians available for ongoing maintenance and repairs when your system needs attention.
Split systems are a flexible option when you want independent heating and cooling in selected parts of your home rather than conditioning every room at once.
Split system air conditioning can suit homeowners who want targeted comfort in individual rooms or smaller areas, including bedrooms, living rooms and home offices.
With heating and cooling available from one system, reverse cycle split systems make it easier to maintain comfortable indoor conditions throughout changing seasons.
The right split system depends on more than the room you want to heat or cool. System capacity, placement and how you use the space can all affect efficiency and performance.
Based on Trimech’s own split system service data, these are the problems our technicians most commonly diagnose and attend.
Data as of October 2026
Split systems are recorded when rooms do not reach the expected heating or cooling output, sometimes without an obvious error code showing.
Fan motor, bearing, blade or capacitor faults can stop the indoor or outdoor fan operating correctly and may leave the unit in fault.
Water leaks are often linked to condensate drains, trays, drain socks or pumps not clearing moisture away from the split system.
Dirty filters, coils or fan barrels restrict airflow through the split system and can reduce heating or cooling performance.
The figures above are Trimech own estimates, based on patterns we've observed across our internal job records tagged to Split system air conditioning jobs - not an independent industry study. Parts required will vary by cause and property.
Split system costs vary with unit capacity, brand, installation requirements and the work needed on site. These general ranges can help with budgeting before you request a tailored quote.
As a general guide, a supplied and installed split system may cost around $1,200–$4,500+. Smaller bedroom systems generally sit at the lower end, while larger units for open-plan living areas can cost more. Your final price depends on the system and installation requirements.
Installation is not the only cost to consider. A routine split system service generally starts around $180, while repairs vary depending on the fault, replacement parts and labour involved. Trimech can assess your system and provide a quote for the work required.

The right size depends on the room’s floor area, ceiling height, insulation, windows and sun exposure. Trimech can assess the space and recommend a split system with suitable capacity.
A standard split system is generally designed to condition one room or a defined area. If you want independent comfort across several rooms, multiple split systems or another air conditioning setup may be more suitable.
The indoor unit should be positioned to distribute conditioned air effectively, while the outdoor unit needs suitable airflow and access. Trimech considers both when planning the installation.
Regular servicing helps keep your split system operating reliably and can identify issues before they develop further. The appropriate schedule can vary with usage, environment and system condition.
