Hi, my name is Katrina, your dedicated local HVAC Hygienist in Darwin.
I am passionate about indoor air quality and the real impact that poor air conditioning hygiene can have on the health of your family members, staff, and visitors. With a background in health sciences, including work in pathology, flu vaccine production, and sterilisation, I bring a deep scientific understanding to every job.
I care about your health and the wellbeing of everyone who spends time in your home or business. Contaminated air conditioners can spread mould, bacteria, dust mites, and allergens — something I know all too well from my health-related experience. HVAC hygiene is a specialised field, just like pathology. When performed correctly by a trained technician using industry-best products, it delivers lasting health benefits to everyone in the room.
Outside of work, I love giving back to the Darwin community. You’ll often find me volunteering weekly at Crocodylus Park, working with animals, or wearing my CareFlight volunteer shirt while raising funds and awareness for this life-saving organisation. I also enjoy participating in beach clean-ups and environmental working bees. At home, I’m a proud mum to two teenage boys — you might spot our family riding bicycles around Darwin or enjoying a fun game of tennis.
I truly believe the Sanitair Air Conditioning Hygiene System and Protectair™ products are the best in class — proven over 20+ years across Australia. I take great pride in improving indoor air quality across the Top End, one air conditioner at a time, using my education, experience, and commitment to excellence.
I look forward to meeting you and helping create a healthier environment in your home or business.
Darwin’s extreme tropical climate — with its intense build-up season, high humidity, heavy wet season downpours, and year-round warmth — creates the perfect breeding ground for mould and bacteria inside air conditioning units. Neglected systems can quickly develop musty odours, reduce cooling performance, increase energy bills, and trigger allergies, asthma, or respiratory issues.
At Sanitair Darwin, we don’t offer quick surface cleans. We use our proven Low pressure on wall deep-cleaning process and premium, non-toxic Protectair™ cleaners & sanitisers that are safe for your family, pets, and sensitive AC components.
Many operators promise a fast aircon clean in 20–30 minutes. At Sanitair, our premium service takes 60+ minutes per system to ensure a thorough, lasting result.
Here’s why Darwin residents and businesses trust us:
Every service includes a full system inspection and practical advice tailored to Darwin’s humid tropical conditions.

Unfortunately many new start up competitors in our industry do not know what they are doing and just see aircon cleaning as a way of making a quick buck or supplementing their other struggling businesses. Businesses like general cleaning, carpet cleaning, solar panel cleaning, pest control or lawn mowing and they obtain their training from watching You Tube videos. Sanitair are the Award Winning pioneers of air conditioning cleaning in Australia. For 19+ years we have only been cleaning air conditioners and that is all we do. Our technicians are highly trained to correctly and safely clean & sanitise and restore air conditioners without damaging them.
Sanitair offers a 12 Month Mould Free & Leak Guarantee on all Premium Services. We address all issues promptly as we want our customers for life and we DO NOT charge call out fees. If you are not happy, we quickly return and rectify any issues – We will not ignore your calls or disappear altogether.
A bigger problem from cheaper cleans is that the poorly trained operators often use dangerous practices, incorrect and harmful chemicals which creates a bigger problem and can put room occupants at risk. Sanitair uses only industry proven Protectair™ products which are Non-Caustic, Non-Toxic.
A premium professional air conditioner clean and sanitise on a system with moderate contamination should take (1) technician approximately 60+ minutes to complete properly. If you experience or are told 20-30 minutes you will not be getting a professional deep clean that is the industry standard set by Sanitair.
Unfortunately, most cheaper competitors are not insured and when something goes wrong disappear off the face of the earth, leaving their unhappy customers with huge repair bills.
