Why It Matters: Aussie Conditions Need Tailored Solutions

Climate & Coil Care: It’s Not One‑Size‑Fits‑All

Australia’s climate varies widely across cities—humid North Queensland, dry Perth summers, coastal salt in Sydney and Gold Coast. Each environment creates unique challenges for different AC types:

• Split systems in inland suburbs pick up dust, pollen, and pet hair.

• Ducted units in family homes accumulate mould in humid bathrooms.

• Window‑mounted ACs in Melbourne’s rental flats often get neglected, stinking up living rooms.

• Packaged or rooftop units in Brisbane commercial sites are exposed to grease, insects, and grime.

• Heat pumps and evaporative coolers need enzyme cleaners to tackle scale and bacteria.

• Portable and reverse‑cycle units in coastal towns suffer from salt spray and coral dust.

Using a generic cleaner usually only tackles part of the problem—and often leaves behind eco-unfriendly residue or worse, damages your coils. That’s why equipment‑specific cleaners matter. They’re designed with the right pH, surfactants, and rinsing requirements for each system type. And when you focus on safety and eco-compliance, you're ticking important boxes under Australian standards—and being mate‑friendly to your customers and tradies.

How It Works: Tailored Cleaning, Tiny Effort

1. Split System Coil Cleaner

Common issue? Dust, pet hair, and pollen clogging those indoor evaporator coils. Enter Viper Aerosol Coil Cleaner (RT375A)—a food-grade, non‑toxic aerosol that foams deep into the coils, loosening debris. No need for heavy rinsing—just wait for condensate to do the rest.

Works a treat for DIYers or tradies servicing units in Sydney living rooms or regional QLD homes. Best part? It’s biodegradable and leaves no nasty smells.

2. Ducted Air‑Con Maintenance

Ducted systems often need a heavier formula. We recommend Viper Heavy Duty (RT390G/RT300G) concentrate. Dilute it in a foam gun for whole‑house ducted cleans in Melbourne or Brisbane.

It dissolves grime, mold, and grease in one pass—with no acidic residues. Simply rinse where needed, pat dry, and go.

3. Window Air‑Con Cleaning (Melbourne Rentals)

Space is tight and take-downs messy. A quick clean with the aerosol RT375A gets the job done without full removal. Quick spray, short wait—done. It’s the best choice when there’s no drainage access and minimal space to work in.

4. Packaged Units & Commercial Cleaners (Brisbane)

For large packaged rooftop units or multi‑story offices, go big with the 20 L concentrate of Viper Heavy Duty Coil Cleaner (RT390G). Dilution rates up to 20:1 mean less rinsing and more coverage—perfect for tradies servicing schools or offices without disrupting the site.

5. Heat Pump Maintenance (Perth Homes)

Perfect summer/winter split in Perth calls for versatile cleaners. Use the Viper RT350G Evaporator Coil Cleaner (EVAP+)—an enzyme‑rich, non‑rinsing formula that keeps coils cleaner for longer and self‑digests organic matter over 72 hours.

Great when you can spray and forget, ideal for relentless Perth dust.

6. Evaporative Cooler Cleaning (Adelaide)

These beasts need bacterial and scale control. The enzyme-based EVAP+ handles build-up without draining the swamp—or polluting local waterways. Plus, it's safe for the aluminum pads in Adelaide’s climate.

7. Reverse Cycle AC (Gold Coast)

Gold Coast humidity + salt + HVAC = corrosion central. One smart move: finish with Viper Coil Coating Aerosol (RT640A) after cleaning with RT375A or HD. That invisible barrier keeps salt and moisture at bay—perfect for coastal unit longevity.

8. Commercial Refrigeration Coil Cleaner (Darwin)

In Darwin’s humidity and mud season, food-safe cleaners are non-negotiable. Use Viper RT375A for fridges and ice machines. It’s NSF-certified and gentle on nickel plating, so it won’t affect food safety or equipment.

9. Industrial Chiller Maintenance

Chillers will be cleaned by licensed techs—and they love Viper Heavy Duty mixed at 10:1 or less and rinsed off with pressure washers. It’s powerful enough to strip grease but without that nasty acid touch.

10. Portable Air‑Con Solutions

Portable units need a targeted product—again, RT375A aerosol is your friend. Minimal mess, fast, efficient. No need for hoses or water access—great for rentals, offices, and caravans across Australia.

Aussie Tips: Tradie-Smart & Homeowner-Ready

Label Literacy

When buying, check for these details:

• CAS numbers listed on Safety Data Sheets

• “Biodegradable” and “nsf/food-safe” certifications

• Rinse instructions specific to coil type

Dilution Dos & Don’ts

• RT390G: mix at 20:1 for condensers, 10:1 for evaporators

• For portable and window units, no hoses—go aerosol

Environmental and Safety Points

Australian standards matter: all Viper formulas are water-safe, biodegradable, and non-toxic. That covers your workplace safety (WHS) obligations and keeps you out of trouble with councils or EPA zones—especially if you’re in coastal or sensitive regions.
