Split system servicing: what's included and how often it's needed
By True Line Air Conditioning · 4 min read
A split system that never gets serviced doesn’t fail loudly — it fades. It cools a little less, costs a little more to run, and smells a little mustier each summer until one 40° day it gives up entirely, along with every other neglected unit in Melbourne, and you’re in a three-week repair queue. Servicing is how you stay out of that queue.
What a proper service includes
- Deep clean of filters and indoor coil— where dust, mould and the “dirty sock” smell live
- Outdoor coil clean and inspection — leaves, dirt and (near the bay) salt corrosion all strangle airflow
- Condensate drain check and clear— the cause of most “why is my wall wet” calls
- Operating check — temperatures, airflow, refrigerant performance, electrical connections and mounts
A filter rinse you can do yourself between visits (your manual shows how, and it’s worth doing each season). The coil cleaning, drain and electrical checks are the parts that need a technician.
How often?
Once a year for a typical home — ideally in spring, before the first heatwave finds the problem for you. Systems near the bay, in dusty environments, or running near-daily (home offices, commercial spaces) justify a closer look more often. Businesses running cooling through trading hours should be on a planned maintenance schedule, not a break-fix cycle.
What it protects
Three things: running costs (a clean system moves more air for the same electricity — more on running costs here), air quality(the alternative to cleaning the coil is breathing what’s on it), and lifespan — the difference between a system that lasts eight years and one that lasts fifteen is mostly maintenance.
How we do it
Service and repairs are available for all major brands, including systems we didn’t install — same-week service as standard, next-day priority for care plan members. With our install packages, the first year of care is built in: every Trueline Care and Premium installation includes the Year-1 Care Plan— annual service & clean, priority booking, next-day response and 10% off repairs — and after year one it continues at $29/month or simply ends, no lock-in.
