Multi Split Air Conditioning Maintenance Sydney

Once a year for most Sydney homes, ideally in spring before the cooling season. If you have pets indoors, live near the coast or run the system most days, every six months is a better rhythm. Rental properties should be serviced at each tenancy change to protect the bond and the next tenant.

Every indoor head gets filters cleaned, coil inspected, drain flushed and airflow measured. The condenser gets a coil clean, electrical check and refrigerant pressure test. We then run the whole system in heating and cooling and report on anything likely to need attention, separately quoted if work is required.

Yes. Each head has its own filter, coil and drain, so each one collects its own dust and can block independently. Servicing only the frequently used heads leaves the others degrading quietly. When you book, tell us the total head count so enough time is allowed for all of them.

Yes, and you should. Lift the front panel on each head, slide the filters out, rinse under lukewarm water and let them dry fully before refitting. Every month or two through summer is plenty. That habit alone makes a real difference to airflow and running cost, and it costs nothing.

A musty smell from a single head usually means mould or bacteria in that unit drain pan or on its evaporator coil. It happens when the drain does not fully drain and water sits in the pan. A deep clean and sanitise fixes it, and we check the drainage fall while we are there so it does not recur.

Yes, usually. Dirty coils and restricted airflow make the condenser work harder for the same result, and that shows on the bill. On a multi split the effect multiplies, because a clogged head runs inefficiently while the condenser compensates. Cleaning the coils and confirming refrigerant charge restores efficiency across the system.

Roughly an hour per two heads as a guide, so a two head system is usually a couple of hours and a five head system most of a day. Access matters, as does condition. We confirm the expected time when booking so you can plan access, parking and whether anyone needs to be home.

Working is not the same as working well. A system can cool adequately while a coil is half blocked, a drain is close to overflowing and refrigerant is slightly low. Servicing finds those problems while they are cheap. It also keeps the manufacturer warranty valid, since most brands require documented servicing records.

Yes. We service multi splits regardless of who installed them. We will check the original installation while we are there and flag anything causing repeat faults, such as undersized pipework, poor drainage fall or a condenser that was never commissioned properly. You get a straight answer on what needs attention.
