When Sydney welcomes travellers from around the globe—whether they’re here for the Harbour Bridge views, a cheeky surf at Bondi, or a good feed at Circular Quay—one thing that can ruin their stay quicker than a seagull stealing chips is a dodgy aircon. And in the hotel game, nothing turns off a guest faster than stale, musty air coming from a poorly maintained split system.
If you run or manage a hotel in Sydney, keeping your split system air conditioners in top shape isn’t just about guest comfort. It’s about health, hygiene, reputation—and staying compliant with New South Wales tourism industry standards.

Let’s dive in.
Why Split System Cleaning Matters for Sydney Hotels
Sydney’s a stunner—but it’s no secret the city’s humidity, coastal salt, and urban air can clog an aircon faster than a summer nor’easter.
For hotels, this means split systems work overtime. The result? Dust build-up, mould growth, and bacteria circulating into every guest room. Not only does this pose a health risk, but it also puts you at odds with NSW tourism and safety regulations.
Clean air matters. Especially when you’re in hospitality.
- Health and Safety: Poor air quality = sick guests = bad reviews.
- NSW Tourism Compliance: Regular HVAC maintenance is expected for commercial accommodation providers.
- Energy Efficiency: Dirty filters mean the system works harder—hello, high energy bills.
- Online Reputation: A bad review about a mouldy room spreads faster than the flu.
Your AC system might be out of sight—but it should never be out of mind.
How Split System Cleaning Works (Simple Steps for Hotel Staff)
Split system cleaning might sound technical, but it’s honestly a job your maintenance team can knock over with the right tools and a bit of Aussie can-do spirit.
Here’s how it works:
- Switch Off the Power – Always start safe.
- Remove & Wash Filters – Rinse filters with warm soapy water. Let them dry completely.
- Use a Split System Cleaning Bag – Hang it underneath to catch all the runoff.
- Apply Coil Cleaner Spray – Make sure it’s non-corrosive and safe for indoor use.
- Rinse Thoroughly – Use clean water and let the unit dry before turning it back on.
- Wipe Down Exterior & Controls – Don’t forget those high-touch surfaces.
No tradie needed. Just a solid product setup, and you’re good to go.

Maintenance Must-Knows: Signs It’s Time for a Clean

Your AC might still be blowing air, but is it clean air?
Look out for these warning signs:
- Musty or mouldy smells from vents
- Dust build-up on the fins and outer vents
- Struggling to cool the room despite full settings
- Leaking or dripping from the indoor unit
- Guests complaining about sneezing or dry throats
Sydney’s coastal air is beautiful but brutal on AC units. Ideally, filters should be cleaned monthly and deep-cleaned every 3–6 months depending on usage.
When to Upgrade Your Hotel’s Split System
Even the best-maintained units have a lifespan. Here's how to know when it’s time to say goodbye:
- ❌ Over 10 years old
- ❌ Frequently breaking down or short-cycling
- ❌ Rising power bills
- ❌ Leaking refrigerant
- ❌ Noisy operation or poor air output
Newer split systems offer better air purification, lower energy use, and smart tech for easier maintenance.
Investing in a fresh system = lower complaints, happier guests, and long-term savings.
Client Story: The Paddington Hotel That Avoided a PR Crisis
Let’s talk about Susan. She runs a boutique 28-room hotel in Paddington, known for its rooftop terrace and city views.
Last summer, a travel influencer checked into Room 14 and posted about the musty smell in the aircon. The post gathered steam on Instagram—and Susan’s phone rang off the hook.
Panicked but proactive, she ordered split system cleaning kits from HVAC Shop and had her staff deep-clean all units within two days.
The influencer updated her post with praise for the hotel’s quick response—and bookings surged again within the week.
Now, Susan logs monthly cleans, uses HVAC Shop's gear, and hasn’t had a complaint since.
