Why Darwin aircons get filthy inside

A Darwin aircon works hard. It runs for long hours through the build-up and the wet, pulling damp air across a cold coil all day. That damp, dark coil is where mould, dust and grime build up.

Rinsing the filter does not reach it. The filter sits in front of the coil, and the mess grows behind it, on the coil fins and inside the fan barrel. Every time the unit runs, that mould and grime circulate through the room.

Clean, repair or replace?

Tick what you have noticed. You get a rough idea of what your aircon needs before anyone opens it up.

Check-up: Nothing obvious, which is good. A yearly clean before the build-up suits most Darwin households.
Clean: Sounds like a dirty coil, fan or drain. A clean usually fixes smells and drips. If it is not cooling, tell us when you book, because a clean will not fix a fault.
Repair: Probably more than dirt. We test the unit and the electrics behind it in the same visit, then give you the options and a price.
Replace?: Lots of signs at once. We will tell you whether it is worth fixing or replacing, and why. Quotes for new installs are free.

What a full aircon clean from Fosters includes

Every Fosters aircon clean covers the indoor and outdoor unit. Here is what we do on a standard wall-mounted split system.

Covers and filters off
We take off the front panel, filters and louvres and wash them by hand.
Indoor coil cleaned and rinsed
We fit a wash bag under the unit, spray a coil cleaner onto the coil fins and leave it in for 15 minutes, then rinse it off.
Fan barrel cleaned
The fan barrel is the round fan inside the unit. It collects the black build-up you see in our before photos, so it gets a proper clean.
Drain tray and drain line cleared
We clean the tray and flush the drain line. A blocked drain line is a common cause of an indoor unit dripping water down the wall.
Outdoor unit cleaned
We always clean both the indoor and outdoor unit, and your price covers both.
Test run and tidy-up
We put it back together, run it and check it is working. We leave the site clean and tidy, with a few tips on keeping it running well between cleans.

Ceiling cassettes

Cassettes get a deep clean too. We drop the panel, bag the unit and clean the coil and fan in place, as in the photo above. Tell us on the form if you have cassettes, so we bring the right gear. Cassette cleans start from $275.

Ducted systems

We clean and service ducted systems too: the return air filter, the indoor coil, the drain and the outlets. Ducted cleans are quoted per system.

The guys did a great job cleaning the indoor and outdoor units at our new place. The before and after of the insides of the units were amazing (and disgusting, obviously hadn't been properly cleaned before we moved in).

James S., Google review

Got a quick response to my initial enquiry, which made the whole process easy from the get-go. The team was professional, thorough with the AC cleaning, and left everything neat and tidy.

Frequently asked questions

How often should I get my aircon cleaned in Darwin?

For most Darwin homes, once a year is right, ideally before the build-up starts in September. Units that run all night in bedrooms, homes with allergy sufferers and units that smell musty may need a clean every six months.

How much does aircon cleaning cost in Darwin?

A single split system clean is $165. Book two or more and they are $135 each. Ceiling cassettes start from $275, and ducted systems are quoted per system. We confirm the total before we start.

How long does an aircon clean take?

It depends on the unit and how dirty it is, and cassettes take longer than wall-mounted splits. We give you an idea of the time when we quote. If you book several units, we clean them all in one visit.

Can I just clean the filter myself?

Yes, and you should rinse the filters every few weeks. But the filter only catches the big stuff. The mould and grime build up on the coil and inside the fan barrel behind it, and getting to those means taking the unit apart.

Will my aircon smell better after a clean?

A musty smell usually comes from mould on the coil, fan or drain tray. Cleaning those parts helps with musty smells in most units. If the smell comes back fast, there may be a drainage problem, and we will tell you what we find.

What happens if you find a fault during the clean?

We tell you on the day and explain your options. Sean is licensed for both refrigeration and electrical work, so most faults can be quoted and fixed by the same team. See our air conditioning repairs page for the common ones.
