Air Conditioner Cleaning on the Sunshine Coast

If your air conditioner smells off, barely cools or leaves your air feeling damp and stale — it probably needs more than just a filter rinse. At Allchin Airconditioning & Refrigeration Electrical, we offer proper air conditioner cleaning from our Caloundra base, servicing homes and businesses right across the Sunshine Coast.

We don’t stop at the filters. We deep-clean the coil, barrel fan, drain and casing to remove built-up dust, mould and gunk that restrict airflow and drive up energy use. Our technicians clean all system types — split, ducted, cassette and multi-split — using the right tools and non-corrosive products.

A clean system not only runs better, it lasts longer and keeps your indoor air safer to breathe. Reach out on 0447 347 428 to book your air conditioner cleaning today.

We know what’s hiding inside a neglected air conditioner — mould spores, dirt, bacteria and who knows what else. That’s why our cleaning service goes beyond the surface. We fully disassemble and flush the internal components so your system runs like it should.

Whether your system’s making noise, blowing musty air or just hasn’t been cleaned in a while, we’ll take care of it. We clean split systems, ceiling cassettes, ducted units and even caravan and portable setups. If your system’s part of your daily comfort, it’s worth looking after properly.

Cleaning helps prevent breakdowns, reduces power bills and makes your cooling feel crisp again. And if you’ve got kids, pets or allergies in the house, it’s a smart way to improve the air quality they breathe every day.

How often should I have my air conditioner professionally cleaned?
At a minimum, once a year. For systems used heavily — especially in coastal homes, rental properties or homes with pets — every six months is ideal. While you can rinse filters yourself, professional cleaning reaches deep inside where mould, bacteria and dust build up.

Regular cleaning keeps the system efficient, helps prevent breakdowns and improves air quality.
Can a dirty air conditioner make you sick?
Yes, especially if there’s mould or bacteria inside the unit. When left uncleaned, an air conditioner can spread allergens, spores and other contaminants into the room. This can trigger asthma, sinus issues, headaches or general discomfort — particularly for kids, elderly residents or anyone with sensitivities. A proper deep clean removes the source of those irritants.
What’s included in a professional air conditioner clean?
A standard clean involves removing and washing filters, flushing the evaporator coils, clearing the drain line, cleaning the fan barrel, checking for mould and testing the system.

Some services also include sanitising spray or coil treatments to reduce bacteria growth. It's more thorough than a basic vacuum or surface wipe, and ensures the entire system runs efficiently.
How often should I clean or replace my air filter?
For most units, clean or replace your air filter every 1 to 3 months, depending on usage and the type of filter you have installed. This helps to ensure proper air flow and prevents dust and debris from clogging your unit.
How do I know if my air conditioner needs cleaning?
Common signs include a musty smell when the unit runs, weak airflow, loud noises, water leaks or higher than normal electricity bills. If the unit hasn't been cleaned in over a year — or if you notice black spots on the vents — it's definitely due. Even if it’s still cooling, hidden build-up can affect performance and air quality over time.
How do I clean the outside unit?
Keeping your air conditioner clean is vital to performance. A dirty cooling system won’t work as well and may wear out and need repairs more often and you could even end up having to replace it sooner than necessary. Make sure the outside unit is free of leaves and other debris and wash the dust and dirt off of it, while it’s turned off, on a regular basis.
