Terraces and warehouse conversions put air conditioners in difficult positions: a condenser wedged into a walled rear courtyard, an indoor head mounted three metres up in a room with one doorway. Both make a unit dirty faster than a suburban install.

Why Surry Hills is different
Of 9,666 private dwellings, 2,261 are semi-detached, row or terrace houses — the highest share of any suburb we work in — and only 84 are separate houses. The remaining 5,325 are flats and apartments, a great many of them warehouse and factory conversions.
Most terraces have no eaves, so there is no shaded position available and the condenser takes direct western sun from mid-afternoon. And the indoor head is usually mounted high in a room with a high ceiling and a single doorway, so the same air circulates past the fan barrel over and over, concentrating dust and mould on the blades instead of distributing it.
The Inner city also has more converted industrial buildings than anywhere else we service. They share a specific problem: the indoor head sits four or five metres up and has usually never been touched since installation, because nobody in the building owns a ladder that reaches it. Those are often the dirtiest units we open.

Where the law lets it go
For a heritage item, or a property inside a heritage conservation area, the NSW exempt development rules require an air conditioning unit to be mounted on the ground and installed at or behind the rear building line.
In a Surry Hills terrace that leaves one place: the rear courtyard or light well, which is usually three or four metres square, walled on three sides, often part-roofed, and shared with the bins, the hot water unit and the clothesline.
A condenser in that position has a specific failure mode. It blows hot air into an enclosed box and then draws the same air straight back in. The coil never gets cool ambient air to reject heat into, so it runs hotter than designed, for longer, right through summer. Heat plus a coil already part-blocked by lint and courtyard dust is how a Surry Hills machine ends up drawing far more power than its label suggests while cooling the front room badly.
A clean is maintenance, not development, so nothing we do needs council approval. The rules are still worth knowing, because if a technician ever proposes relocating the condenser to a front wall, a front roof slope or a street-facing parapet on a heritage-listed or conservation-area property, that is a planning problem and not merely a question of taste. The City of Sydney has 75 heritage conservation areas, and Victorian and Federation buildings make up close to 90% of what stands inside them.

After a professional clean
Our services
Full strip-down of the indoor head, chemical clean of the fan barrel and coil, drain flush and outdoor condenser service. From $249 + GST per unit.
The coil behind the filters is where airflow is lost. Cleaned, treated and rinsed through, not wiped over.
Treatment through the barrel, coil and housing to deal with the mould causing the musty smell.
Filters removed, washed and refitted, or replaced where they are past saving.
Coil fins washed down, base cleared and clearances checked so the unit can shed heat properly.
Return air filter, coil and accessible duct runs for ducted systems. From $350 + GST.
Inside your unit
We cannot move the unit, but we can get the coil clear and check the clearances, and we will tell you if a simple change — turning a fence panel, lifting the unit off the ground — would buy back airflow.
Transparent pricing
No call-out fee and no charge for the quote. The same price in every suburb we service.
How it works
Tell us the brand and how many units you have, or send a photo. We come back with a fixed price and a time, seven days a week.
Drop sheets and a containment bag go under the unit before anything comes off the wall.
Cover, filters and fan barrel come off. The barrel, coil and housing are chemically cleaned and rinsed, and the drain line is flushed.
The unit goes back together, gets a sanitising treatment, and we run it and check airflow and drainage in front of you.
About the suburb
Surry Hills sits immediately south-east of the city centre, in the City of Sydney local government area, and it is among the densest suburbs in Australia: the 2021 Census counted 15,828 residents at roughly 12,175 people per square kilometre.
Average household size is 1.8, the smallest of anywhere we service, which means a great many one and two-bedroom terraces and converted apartments with a single split system doing all the work.
The building stock is largely Victorian and Federation terrace, overlaid with a century of warehouse conversion and infill. Almost none of it was designed for mechanical cooling, which is why so much of the air conditioning here is retrofitted into whatever space was left over.
Common questions
No. Cleaning and maintaining an existing unit is maintenance, not development, and needs no approval. The heritage rules apply to installing or relocating a unit, not to servicing one.
It is the most common problem we see in Surry Hills. An enclosed courtyard lets the unit draw back the hot air it has just blown out, so the coil never gets cool air to reject heat into. We cannot move the unit, but we can get the coil clear and check the clearances, and we will tell you if a simple change, like turning a fence panel or lifting the unit off the ground, would buy back airflow.
Yes. High-mounted heads in converted buildings are routine here and we bring the access equipment for them. Tell us the approximate height when you book so we bring the right ladder or platform.
Yes. Ducted retrofits in terraces usually run through the ceiling space or a bulkhead, and we clean the return air filter, the coil and the accessible duct runs. Ducted is quoted per property because the layouts vary so much.
It helps but it is not essential. We are used to working in Surry Hills and we carry equipment in from wherever we can stop. If your street is permit-only or there is no loading zone nearby, mention it when you book.
In almost every case, yes, provided the drain line is flushed at the same time. The smell comes from mould on the fan barrel and from water sitting in the tray under a blocked drain, and in a terrace with poor cross-ventilation the mould tends to be heavier than average.
That is worth a clean before anything else, particularly if the condenser sits in an enclosed courtyard. A coil that cannot shed heat and a barrel packed with mould will both cut output without throwing a fault code, so the system tests as working while the room stays warm.
Once a year for a unit in regular use. Units in enclosed courtyards, and heads mounted high in warehouse conversions where nobody checks them, are the ones we most often find have gone five years or more without a clean.
