Servicing and cleaning

Deep clean and odour treatment

A deep clean goes further than a routine service. With a waterproof cleaning bag fitted under the indoor unit, the coil is treated with cleaner and rinsed, the fan is cleaned, the drain tray and line are flushed and sanitised, and the unit is put back together and tested. It is the usual fix for musty smells, black specks from the fan and units that drip because the tray is clogged.

  • Systems not serviced for years

When does a unit need a deep clean?

When it smells musty or damp on start-up, when you can see dust or black growth on the fan blades through the outlet, when it drips water from the front, or when it has not been serviced for a couple of years. A routine service keeps things clean; a deep clean restores a unit that has got dirty.

Is it messy?

No. The cleaning bag catches the rinse water and runs it into a bucket, and dust sheets protect the floor and furniture beneath the unit.

How often is it needed?

Most homes only need a deep clean every few years if the system is serviced annually. Kitchens, pets and homes near busy roads may need it more often.

FAQ

Deep clean and odour treatment: your questions

Will a deep clean stop the smell?

In most cases, yes, because the smell comes from growth in the coil, fan and drain tray, which the deep clean removes.

Can I deep clean it myself?

Light filter cleaning, yes. A full coil and fan clean needs the unit partly stripped and is best done by an engineer.

Do you clean outdoor units too?

Yes, outdoor coil cleaning is part of a service and can be added to a deep clean visit.
