Coil Cleaners

Air conditioning systems need to be cleaned regularly to maintain performance, efficiency, air quality, and system longevity. Here’s a breakdown of the key reasons why cleaning is essential:
1. Maintain Cooling and Heating Efficiency
Dust, dirt, and debris on coils, filters, and fans restrict airflow and reduce heat exchange. This means the system must work harder to reach the desired temperature, using more energy and taking longer to cool or heat a space.
2. Improve Indoor Air Quality
Over time, mould, bacteria, pollen, and dust can build up in filters and evaporator coils. When the air conditioner runs, these contaminants are blown into the air, leading to poor indoor air quality and potential allergy or respiratory issues.
3. Prevent Breakdowns and Extend Equipment Life
Dirt buildup puts extra strain on components such as compressors, fans, and motors. Regular cleaning helps prevent overheating, corrosion, and component failure, extending the lifespan of the system.
4. Reduce Running Costs
A clean system runs more efficiently and consumes less electricity, lowering energy bills. Blocked filters and dirty coils can increase power consumption by up to 30%.
5. Avoid Unpleasant Odours
Mould and bacteria in the evaporator coil or drain pan can cause musty or sour smells. Cleaning removes organic buildup and keeps the air smelling fresh and clean.
6. Maintain Compliance and Warranty
In Australia, regular servicing and cleaning are often required to comply with manufacturer warranties and industry standards (e.g., AS/NZS 3666 for microbial control). Neglecting maintenance can void warranties or lead to non-compliance with health and safety regulations in workplaces.
7. Prevent Water Leaks
A blocked condensate drain can cause water to back up and leak inside the unit or building. Cleaning the drain pan and line prevents water damage and mould growth.

A coil cleaning machine is a specialised tool used to clean the evaporator and condenser coils in air conditioning and refrigeration systems. It delivers water, cleaning solution, or a mix of both under controlled pressure to remove dirt, dust, grease, and biological buildup from the coil fins — without damaging them.
Coil cleaning machines make it faster, safer, and more effective to clean coils — especially when:
• Coils are large or hard to access, like rooftop condensers or ducted indoor units.
• Dirt and debris are deeply embedded between the fins.
• Technicians need consistent water pressure without risking coil damage.

There are several types of coil cleaning machines, each designed for different applications, system sizes, and environments. The main difference between them is how they deliver water and cleaning solution to the coils, and whether they are intended for light-duty residential or heavy-duty commercial/industrial cleaning.
Below is a detailed breakdown
1. Portable Coil Cleaning Machines

Compact and lightweight units designed for technicians on the move. They are ideal for cleaning split systems, fan coils, and small commercial units.
Key Features:
• Battery-powered or corded electric.
• Water connection or Built-in water tank.
• Can spray water or a mix of water and detergent.
• Pressure range: 100–200 psi (safe for delicate indoor coils).

2. Chemical Applicators & Foaming Machines
Description:
Designed to apply cleaning chemicals (especially foaming coil cleaners) evenly onto coil surfaces.
Key Features:
• Battery driven pump or water pressure.
• Adjustable nozzles to control foam thickness and spread.
• Can be used with or without a water source.
Best For:
Indoor evaporator coils, regular maintenance, and areas with limited water drainage.

3. Aerosol can, chemical cleaning spray:
This is more of a DIY solution
Best For:
Small Indoor evaporator coils
