Air Conditioning Repairs and Servicing for Adelaide
A system that is not cooling, leaking water or smelling musty usually needs a fast diagnosis and the right repair.
From poor cooling and refrigerant leaks to noisy fans and blocked drains, we carry out air conditioning repairs in Adelaide on all major brands, plus regular servicing and deep cleaning. As an ARC-licensed team, Simms Plumbing & Air Conditioning gets your system healthy and efficient again.
The Air Conditioning Repairs We Handle
Here are the air conditioning repairs we carry out across Adelaide, on split and ducted systems:
-
Not Cooling or Heating
When a system blows warm air or will not heat, we diagnose the cause, from low refrigerant to a failed component, and get it cooling and heating properly again fast.
-
Refrigerant Leaks and Regas
Low or leaking refrigerant kills cooling, so we find and repair the leak, then recharge the gas under an ARC refrigerant handling licence to the manufacturer's exact specification every time.
-
Water Leaks and Drainage Faults
A split system dripping water inside usually has a blocked or misaligned drain, so we clear the condensate line and reset the drainage so water runs safely back outside again.
-
Noisy or Vibrating Units
Rattles, grinding or loud humming point to worn fan bearings, loose mounts or debris, so we trace the noise and repair or replace the part so the unit runs quietly.
-
Weak Airflow or Poor Cooling
If the air barely moves or the room never cools, we check filters, coils, the fan and refrigerant charge, and restore the airflow and cooling the system should always deliver.
-
Faulty Controls and Thermostats
When the remote, timer or thermostat will not hold a setting, we test the controls and sensors and get the system responding to your commands the way it always should.
Air Conditioning Servicing and Cleaning
Regular servicing and cleaning keep your system efficient, healthy and reliable right through an Adelaide summer:
-
Scheduled Air Conditioning Service
A regular Adelaide air conditioning service keeps efficiency up and breakdowns down, so we check pressures, clean key parts and catch small faults before they become expensive repairs later on.
-
Filter and Coil Cleaning
Clogged filters and dirty coils choke airflow and drive up power bills, so we clean them thoroughly, which the government also recommends to keep your system running efficiently all year.
-
Mould and Odour Cleaning
A musty smell means mould in the unit, so we deep-clean it to clear the health effects of mould in the home and leave the air fresh and healthy again.
-
Commercial and Industrial Cleaning
For commercial and industrial air conditioning cleaning across Adelaide, we service larger systems on shops, offices and warehouses, keeping airflow, hygiene and efficiency where they need to be all year.
Why Timely Repairs and Servicing Pay Off
Acting early on a struggling air conditioner saves you money and hassle in several ways:
-
Lower Power Bills
A struggling unit works harder and burns more power, so a quick aircon repair or service often pays for itself through the energy you stop wasting every single hot day.
-
Avoiding Bigger Breakdowns
Small faults like low gas or a dirty coil strain the whole system, so fixing them early stops a minor issue turning into a costly compressor or motor failure later.
-
Healthier Air at Home
A dirty or mouldy system pushes spores and dust through every room, so cleaning and servicing keep the air your family breathes fresh, especially for anyone with asthma or allergies.
-
Comfort When You Need It
Most air con repairs are needed on the hottest day of the year, so booking a service before summer means your system is ready well before the real heat arrives.

Common Air Conditioning Faults in Adelaide Homes
A few faults are behind most of the repair calls we take across the southern suburbs:
-
Blowing Warm Air
The most common call is a system blowing warm air, usually from low refrigerant, a dirty coil or a tired compressor, all of which we can test and repair quickly.
-
Water Dripping Inside
Water dripping from an indoor unit points to a blocked condensate drain or frozen coil, so we clear the blockage and stop the leak before it damages walls or ceilings.
-
Bad Smells When Running
A musty or sour smell when the system starts almost always means mould or bacteria inside, so a thorough clean clears the odour and the health risk in one go.
-
Tripping or Not Turning On
A unit that trips the power or will not start has a fault we diagnose safely, then repair the cause or advise the right fix so it runs reliably again.
Repairs and Servicing for Every Property
We repair and service air conditioning at all kinds of properties across southern Adelaide:
-
Family Homes
In homes around Aberfoyle Park, Woodcroft and Hallett Cove, we keep split and ducted systems cooling reliably, with quick repairs and servicing that fit around busy family routines and budgets.

Frequently Asked Questions About Air Conditioning Repairs
These are the repair and service questions Adelaide customers ask us most:
How much do air conditioning repairs in Adelaide cost?
It depends on the fault and parts, so we give a fixed price upfront after diagnosing it; a regas or clean costs far less than a major component repair.
Why is my aircon not cooling?
Common causes are low refrigerant, a dirty filter or coil, or a tired compressor. We diagnose the exact reason on site and tell you the best fix before starting.
Do you repair all air conditioner brands?
Yes. We repair and service all major split, multi-head and ducted brands, and our ARC-licensed technicians can handle any refrigerant work your system actually needs.
How often should I service my air conditioner?
Once a year is ideal, usually before summer. A yearly service keeps the system efficient, catches small faults early, and helps avoid breakdowns on the hottest days.
Can you clean mould out of my air conditioner?
Yes. We deep-clean the filters, coils and internal parts to remove mould, bacteria and odours, leaving the air your family or staff breathe noticeably cleaner and fresher.
Are your air conditioning repairs guaranteed?
Yes. Simms Plumbing & Air Conditioning backs every repair and service with a lifetime labour warranty, so if our workmanship fails, we return and put it right.
