Split System Reverse Cycle Servicing in Melbourne


A reverse cycle split system is one of the most popular ways to heat and cool a Melbourne home, with a wall-mounted indoor head connected to a compact outdoor unit. Because it runs in both summer and winter, it works hard all year, and the indoor coil and barrel fan quietly collect dust, dirt and mould that a filter wash alone will not remove. Regular servicing keeps it efficient, healthy and reliable. BM Heating & Cooling provides thorough split system reverse cycle servicing across Melbourne, from our base in the northern suburbs.

Our licensed technicians do far more than rinse the filters. We deep-clean the indoor head, chemically clean the coil, treat mould and bacteria, flush the drain, check the refrigerant and electrics on the outdoor unit, and test both heating and cooling. You get a system that runs quietly, smells clean and costs less to run. Whether you bought the system from us or not, we can look after it.

Skipping a service is a false economy. A dirty coil and barrel fan blow mould and allergens through the room, a choked filter makes the system work harder for less comfort, and small faults tend to become breakdowns on the hottest or coldest day of the year. A yearly service is cheap insurance against all of that.

We service reverse cycle split systems throughout Reservoir, Preston, Bundoora, Thomastown, Epping, Coburg, Brunswick, Heidelberg and right across the Melbourne metro area.

What a Split System Reverse Cycle Service Includes


A proper service covers the indoor head, the outdoor unit and a full function test. Here is what our technicians do.

Indoor head: remove and wash the filters, take off the front cover and plastics, deep-clean the barrel (blower) fan where most mould and dust builds up, chemically clean the evaporator coil, and apply an anti-bacterial treatment to the coil, vanes and chassis.

Drain and tray: clean the drain pan and flush the condensate drain line to clear the algae, dust and insects that cause the indoor unit to drip and leak.

Outdoor unit: clear debris and clean the condenser coil and fins, check the refrigerant pressures and look for leaks, and inspect and tighten the electrical connections, fan motor and capacitor.

Test and report: run the system in both heating and cooling, test the remote and controls, check airflow and the temperature difference across the coil, then give you an honest report on the unit's condition and anything that needs attention.

Signs Your Split System Needs a Service


Split systems usually warn you before they fail. Book a service if you notice any of these.

A musty or mouldy smell: a damp, musty smell when the unit starts up, or visible black mould on the vanes and louvres. This is mould on the coil and barrel fan, and a filter wash will not fix it.

Water leaking from the indoor unit: water dripping down the wall usually means a blocked or dirty condensate drain that needs flushing.

Weak, warm or costly: weak airflow, not reaching the set temperature, or rising energy bills for the same usage.

Noises or ice: a noisy, rattling fan, or ice forming on the pipes or indoor unit, which points to low refrigerant or restricted airflow.

Catching a problem early is almost always cheaper than a mid-season repair, and it stops a small fault from damaging the compressor, which is the most expensive part to replace.

Why Regular Servicing Matters


Lower Running Costs

A clean, correctly charged split system uses noticeably less power than a neglected one. Dust on the coil and a low refrigerant charge quietly push your bills up.

Healthier Air

The coil and barrel fan are where mould, bacteria and allergens collect and then get blown into the room. A chemical clean and anti-bacterial treatment keep the air you breathe clean.

Reliability & Warranty

Servicing catches leaks, worn parts and electrical faults early, extends the life of the system, and keeps your manufacturer warranty valid with a documented service history.

How Often to Service, and the Brands We Look After


For a reverse cycle split system that runs in both summer and winter, once a year is the standard. Autumn, before the winter heating season, is the ideal time, and booking early beats the mid-winter rush. If you have pets, allergies, or run the system hard, a service every six months keeps the coil and air cleaner.

You do not need to have bought your system from us for us to service it. Our technicians are trained across all the major brands sold in Melbourne, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Kelvinator, Braemar and Hisense.

If your unit is older and a repair is no longer worth it, we will tell you honestly and explain your replacement options, with no pressure and no upselling. Every service is carried out by a licensed, experienced technician who turns up on time, keeps your home clean, and leaves the system tested and running the way it should.

Split System Reverse Cycle Servicing FAQs


Once a year is the standard for reverse cycle units, since they run in both summer and winter. Book in autumn before the heating season, or every six months if you have pets or allergies.

Filter and barrel-fan clean, an evaporator and condenser coil clean, an anti-bacterial and mould treatment, a drain flush, a refrigerant pressure check, an electrical inspection, and a test of both heating and cooling modes.

Mould growing on the evaporator coil or in the drain tray. A filter wash will not fix it. It needs a chemical coil clean and an anti-bacterial treatment, which is part of a full service.

Usually a blocked or dirty condensate drain line or drain tray. A service flushes the drain and clears the blockage so it stops dripping.

You can wash the filters and wipe the exterior. Coil cleaning, refrigerant checks and electrical work must be done by a licensed technician. Handling refrigerant without a licence is illegal in Australia.

A standard service is usually 30 to 60 minutes per unit. A deep chemical clean takes longer, around an hour to 90 minutes per head.
