Cleaning & Preventative Maintenance for Air Conditioners & HVAC Systems
Keeping coils, filters and drain pans clean is one of the simplest ways to keep air conditioners running efficiently, improve indoor air quality and reduce breakdowns. In this Cleaning & Preventative Maintenance range you'll find split system cleaning kits, reusable wash bags, coil-safe cleaners, Hydrocell portable pressure washers and HVAC cleaning tools – all selected for real-world work in Australian conditions.
Why AC cleaning and preventative maintenance matters
- Restore airflow and efficiency – Dirty filters and clogged coils make systems work harder, driving up power bills and reducing comfort.
- Improve indoor air quality – Removing biofilm, dust and mould from coils and drain trays helps control odours and improve IAQ.
- Cut breakdowns and call-backs – Regular cleaning of heat-transfer surfaces and drains supports more reliable operation.
- Support compliance and duty of care – Using appropriate PPE and handling cleaning chemicals correctly helps you meet WHS obligations on site.
What you'll find in this Cleaning & Preventative Maintenance range
1. Air conditioner cleaning kits & wash bags
Build a complete "bag, clean and rinse" workflow with split system cleaning kits and reusable wash bags designed for wall-mounted indoor units. These kits pair AC-safe cleaners with correctly sized covers so you can flush coils and drain trays without soaking walls, floors or electronics.
If you want more bundled options, explore our dedicated air conditioner cleaning kits collection.
2. Coil cleaners & HVAC cleaning chemicals
This range includes coil-safe cleaners and concentrated wash solutions suited to evaporator and condenser coils, drain pans and housings. These products are matched to HVAC use rather than generic household cleaners to help protect aluminium fins, copper tubes and plastics.
For more specialised chemicals, visit our Cleaning Chemicals collection.
3. Hydrocell portable pressure washers & accessories
Hydrocell portable pressure washers, hoses, spray wands and brass nozzles give you controlled, garden-hose style pressure for rinsing coils and drain trays. They are ideal for tradies and maintenance teams who need portable rinsing power for multiple cleans per day or sites without easy tap access.
To build out your setup, also check our Hydrocell pressure washer collection and Hydrocell accessories & spare parts.
4. Drain & condensate maintenance
Blocked drains and trays are a common cause of leaks and ceiling damage. Within this collection you'll find drain accessories and cleaning tools that make it easier to flush trays and outlets as part of your regular maintenance routine.
5. Hand tools & cleaning accessories
Round out your kit with spray wands, nozzle kits, adaptors and hand tools that support safe access and efficient cleaning around both indoor heads and outdoor condensers.
Choosing the right cleaning setup
For tradies and maintenance teams
- Start with a dedicated AC cleaning kit that includes a reusable bag and coil-safe cleaner for the split systems you service most.
- Add a portable pressure washer such as a Hydrocell unit with genuine hoses, wands and nozzles for controlled rinsing.
- Carry spare consumables – extra cleaner, bags and accessories keep you moving through full days of cleaning without compromise.

For homeowners & DIY users
- Choose a DIY-friendly split system cleaning kit with a clear set of instructions and a good-quality wash bag.
- Clean or replace filters regularly during the cooling or heating season, based on dust levels and usage.
- Use gentle, AC-safe cleaners and avoid harsh chemicals or high pressure on delicate fins and electronics.
Any work on the refrigerant side of the system – including charging, recovering or opening the refrigeration circuit – should only be carried out by a licensed air conditioning technician.
Safe use & compliance
- Always switch off power at the isolator or switchboard before cleaning indoor or outdoor units.
- Wear appropriate PPE (such as gloves and eye protection) and follow the label and SDS for any cleaning chemicals you use.
- Protect walls, floors and electrical components with wash bags and drop sheets so water and cleaner are properly contained.
- Follow the manufacturer's instructions for your air conditioner and cleaning products to avoid damage and preserve warranties.
- Engage a licensed ARCtick technician for any work involving refrigerant, complex faults or major disassembly.

Cleaning & preventative maintenance FAQ
How often should I clean my air conditioner?
For most Australian homes, filters should be cleaned every few months during heavy use. A deeper professional clean that includes coils, drain trays and outdoor units is often recommended every 12 months, ideally before peak summer or winter.
What's the difference between a DIY cleaning kit and a full HVAC service?
A DIY cleaning kit lets you clean accessible parts of the system – filters, coils and drain trays – using a wash bag, cleaner and careful rinsing. A full HVAC service also checks refrigerant charge, electrics, sensors and controls, and must be completed by a licensed technician for any refrigerant work.
Are coil cleaners safe for all air conditioners?
Only if they are designed for HVAC coils and used as directed. Choose coil-safe or pH-neutral formulations intended for aluminium fins and copper tubing, and always follow the instructions and SDS provided by the manufacturer.
Do I need a portable pressure washer for split-system cleaning?
Not in every case. For light maintenance, a pump sprayer and wash bag may be enough. A portable pressure washer is most useful for tradies and maintenance teams who want faster, more thorough rinsing on multiple systems per day or sites without easy access to a garden hose.
When should I call a licensed air conditioning technician?
Call a licensed technician if you suspect refrigerant leaks, the system keeps tripping, ice forms on pipes or coils, or if cleaning requires major disassembly or electrical work. ARCtick licensing requirements mean only licensed people can legally handle refrigerant.
