Air Conditioning Maintenance & Servicing
Regular air conditioning servicing protects your warranty, slashes running costs and stops small faults becoming big bills. Filters, coils, gas and electricals: all checked.
What’s included
How it works
Maintenance & Servicing, explained.
What a proper service covers
Filters, indoor and outdoor coils, the drain and tray, refrigerant charge, electrical connections and a performance check: the full 21-point inspection. Dust and humidity load systems up over a Sydney summer and winter; servicing clears it before it becomes a fault.
How often, honestly
Once a year is the residential minimum and protects most manufacturer warranties. Twice yearly, before summer and before winter, is ideal. High-usage commercial sites benefit from quarterly visits, usually under a maintenance contract.
Guides & advice
MaintenanceMould in your air conditioner: the signs, and what a clean does
A musty smell in the first minute is the usual clue. Here is why the inside of a split grows mould, the two-week filter and the drying run the manuals ask for, what our deep clean covers (and the three things it does not), and the once-a-year rule.

Of the 276 rated models we list, 262 deliver their nameplate capacity in the official GEMS test, so a unit blowing warm air is almost never a weak label. Here is the order a technician works through, and the four checks to do before you call.

Energy & costsWhat air conditioning actually costs to run in Sydney
Most articles that tell you what air conditioning costs to run just make a number up. We use the official government energy figures for real models, times the current median Sydney electricity rate, and we show our working. Here is what it actually costs, and where your own bill might land differently.
ReadMaintenance & Servicing: common questions
How often should I service my air conditioner?
Residential: at least yearly, ideally twice (pre-summer and pre-winter). Commercial high-usage sites: quarterly. Regular servicing keeps efficiency up, protects the warranty and catches small faults before they grow.
Does servicing actually save money?
Yes, in two ways: a clean, correctly charged system draws noticeably less power, and small faults get caught before they take out a compressor. Skipped servicing is the most common reason warranty claims get knocked back.
What can I do myself between services?
Wash or vacuum the indoor filters every month or two, keep leaves and plants clear of the outdoor unit, and run fan-only mode occasionally to dry the unit out and discourage mould.
