Air Conditioning
Service & Repairs
in Cremorne NSW
Cremorne is a flat suburb in the literal sense. Roughly seven in ten homes here are a unit or an apartment and about one in six is a separate house, and the buildings they sit in went up across ninety years. Interwar walk-ups on the streets behind Military Road, red brick from the fifties and sixties, townhouses and duplexes around Ben Boyd Road, new apartment buildings filling the gaps on the main road, and Federation and Californian bungalows on the streets running down towards the water.
Artarmon Air Conditioning services, repairs and deep cleans air conditioning across all of it, and in Cremorne Point, Kurraba Point and Neutral Bay next door, about 10 minutes from our Artarmon base. In a suburb assembled in this many instalments, the age of the building tells us most of what we need to know about the air con before we arrive.
What Your Building's Age
Tells Us Before We Arrive
Cremorne has four broad generations of air con in it, and they fail in different ways.
Interwar and post-war walk-ups. Nothing in these buildings was designed with air conditioning in mind, so all of it is a retrofit. A wall-mounted split inside, pipework down an external wall or through a light well, and an outdoor unit on a bracket, a walkway or a flat roof that belongs to the owners corporation rather than to you. The recurring faults are a condensate drain run to wherever drainage happened to exist, a rusting bracket, and a system sized for the flat before somebody opened the kitchen up.
Nineties and early two thousands infill. Here the air conditioning was designed in, usually a multi-head system with one outdoor unit serving several rooms, or a small ducted system in a townhouse. Those systems are now twenty to thirty years old, which is the age where one outdoor unit serving four rooms becomes the whole problem, because a fault on the outdoor side takes every room offline at once.
Recent buildings on and around the main road. Newer apartments run ducted or multi-head equipment from a condenser on a plant deck, and a good number are still inside the manufacturer's warranty. If yours is, your first call is the builder or the warranty line rather than us, and we will tell you so. In the larger buildings the air conditioning is central plant or VRF under contract, which is outside what we take on.
The houses on the side streets. Federation and Californian bungalows with low-pitched roofs and little height at the eaves, mostly running a retrofitted ducted system or two or three splits. The ducted ones are the oldest installs in the suburb and they show it in the usual places: crushed flexible duct, a return air grille put where it fitted rather than where it worked, and a drain tray in a roof space that never had enough fall.
One thing worth knowing in the older stock. A system fitted before the mid two thousands may still run on R22, which has been progressively phased down for years. It is not illegal and your system is not unserviceable, but supply is limited and the price of the gas alone often settles the repair or replace question.
Air con stopped working or not performing properly?
We diagnose and repair faults across a wide range of air conditioning systems and brands.
Common problems we attend include:
Aircon not cooling
Aircon not heating
Water leaking from indoor unit
Error codes
System switching off unexpectedly
Poor airflow
Unusual noises
Electrical faults
Control faults
Refrigerant leaks
Drainage problems
Outdoor unit faults
Our focus is on correctly diagnosing the cause of the fault before recommending repairs or replacement.
Routine aircon servicing helps keep your system clean, reliable and operating efficiently.
Depending on the type and condition of the system, a service may include:
Clean and inspect filters
Inspect and clean indoor unit components
Clean and disinfect indoor coil
Check condensate drain operation
Inspect outdoor coil
Check electrical connections and components
Test cooling and heating operation
Check airflow and outlet temperatures
Identify signs of wear, leaks or developing faults
We service split system, multi-split, ducted, floor console, and VRV/VRF air conditioning throughout Cremorne.
If your split system has heavy dust, mould or contamination inside the indoor unit, routine servicing may not be enough.
Our aircon deep cleaning service provides a more thorough clean of internal components, including areas that cannot normally be accessed during a standard maintenance visit.
Deep cleaning may be recommended where there is:
Heavy dust build-up
Mould or organic contamination
Persistent odours
Dirty fan barrels
Reduced airflow
Long periods without servicing
A thorough clean can improve airflow, reduce odours and help restore system performance.
Split systems are common throughout Cremorne homes, apartments and smaller commercial spaces.
We service and repair most major brands and can investigate issues including:
Poor cooling or heating
Water leaks
Blocked drains
Refrigerant faults
Electrical faults
Failed sensors
Fan faults
PCB and control issues
Noisy operation
Regular split system servicing can also help identify developing issues before they cause a complete breakdown.
We provide servicing, maintenance and fault diagnosis for ducted air conditioning systems throughout Cremorne.
Common ducted air con problems include:
Poor cooling or heating
Uneven temperatures between rooms
Zone control faults
Restricted airflow
Blocked return air filters
Damaged or disconnected ductwork
Drainage problems
Controller faults
Refrigeration faults
Electrical faults
If a fault requires additional parts or major repairs, we can provide a repair recommendation and quotation following diagnosis.
Old or unwanted air conditioning systems should be properly decommissioned before removal.
We can safely recover refrigerant and disconnect air conditioning equipment for renovations, replacements and property upgrades.
Refrigerant is handled in accordance with the Refrigerant Handling Code of Practice 2025, AS/NZS 5149 and the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989.
Local Aircon Service in Cremorne
As a local air conditioning business on the Lower North Shore, we work right across Cremorne and the neighbouring pockets that share its buildings and its problems:
Cremorne Point: apartment blocks and houses on the peninsula, with outdoor units on balconies, roofs and brackets facing the harbour, where salt air corrodes condenser coils and fixings faster than a street inland.
Kurraba Point: walk-ups and apartment buildings on steep streets running down to the water, where outdoor units often sit on common property and access is by stairs or narrow paths.
Neutral Bay: the same mix of interwar walk-ups, nineties multi-split buildings and newer apartments along Military Road and Ben Boyd Road, including flats above shops that share a roof with the tenancy below.
The houses on Cremorne's side streets: Federation and Californian bungalows running a retrofitted ducted system or two or three splits.
Harbourside humidity is the constant across all of them. An indoor unit running long hours in a damp flat grows mould on its coil and fan barrel, and an outdoor unit near the water needs its coil cleaned properly, not hosed, to last.
If the outdoor unit is on a roof, a walkway or behind another tenancy, tell us at booking who manages access.

Frequently Asked Questions
-
Artarmon Air Conditioning services, repairs and deep cleans air conditioning throughout Cremorne NSW 2090, in apartments, walk-up blocks, townhouses and houses. The business is based in Artarmon on Sydney's Lower North Shore, holds NSW contractor licence 394793C and Refrigerant Trading Authorisation AU60391, and is fully insured. It works on split, multi-split, ducted, cassette, bulkhead, floor console and VRV or VRF systems, whoever installed them.
-
Mostly split systems, because 71 per cent of Cremorne dwellings are flats or apartments, according to the 2021 Census. Artarmon Air Conditioning typically sees wall-mounted splits retrofitted into interwar and post-war walk-ups, multi-split systems in buildings from the nineties and early two thousands, and ducted or bulkhead systems in newer apartments and the Federation and Californian bungalows. The age of the building is usually the best guide to what will fail.
-
Yes. Artarmon Air Conditioning services air conditioning in the mixed-use buildings along Cremorne's Military Road, where a flat's outdoor unit usually sits on the rear roof of the shop below, in a service lane or in a light well. Reaching it often means going through the commercial tenancy, so tell us at booking who manages access and which shop is below you, and the visit is timed around its trading hours.
-
Yes, over time. Artarmon Air Conditioning treats a greasy outdoor unit as a different job to a dusty one, because grease from a kitchen exhaust settles on the condenser coil as an oily film that traps dust, insulates the coil and stops it rejecting heat. Rain does not wash it off, so the coil needs degreasing rather than hosing. It is worth checking on any flat above the restaurants on Military Road.
-
Most likely because they share one outdoor unit. Artarmon Air Conditioning sees this on multi-split systems, which are common in Cremorne apartment buildings from the nineties and early two thousands, where several indoor units run from a single outdoor condenser. A fault on that outdoor unit, its control board or its power supply takes every room offline together, while a fault on one indoor unit usually affects only that room.
-
Usually because a component is drawing too much current or leaking current to earth. The causes Artarmon Air Conditioning tests for first are a failing compressor or fan motor, a weak capacitor, and moisture inside an ageing outdoor unit, which tends to trip a safety switch rather than a circuit breaker. In older Cremorne flats a shared or undersized circuit can add to it. Leave the system off at the isolator until it is checked.
-
Usually because it is moving less air or rejecting less heat than it did. Artarmon Air Conditioning checks the common causes in order: loaded filters and a dirty indoor coil, an outdoor unit with less than 300mm of clear space recirculating its own hot air, and refrigerant lost through a slow leak. In a Cremorne light well shared by several outdoor units, the second cause is the one to rule out first.
