AC repairs, when to call a professional and when to fix at home

Why Is My AC Not Working? 

By 2014, 3 out of every four Australians had air conditioning units. That was double the rate from the late 2000s. Today, that number has skyrocketed and Aussies spend over $3.7 billion in AC during the summer period. A recent survey concluded that over 77% of Australians value their AC unit over most other appliances in their home. Given the sweltering summers in the Land From Down Under these facts aren’t a surprise. What does boggle the mind is that 3 out of 5 AC need maintenance, or aren’t working optimally. Fixing air conditioners in Australia is a full-time job that brings in billions in revenue and offers a constant stream of clients to technicians.  

Air Conditioners, due to their usage and exposure to the elements, need regular check-ups and annual maintenance by professionals. That being said, if your AC unit is on the fritz, sometimes a small DIY fix on your part can do wonders and save you a great deal of money on repairs. It’s important to have your AC unit working properly, it maximizes its function and also, an AC working in peak conditions can bring your energy bill down. 

 Common Fixes For Air Condition Units in Australia. 

Here’s a list of simple fixes you can perform on your AC unit. Repairs and maintenance operations that can save you hundreds of AUD and don’t require a trained professional.  


Yes, we know, it’s like asking, “is the unit plugged in?”, but batteries in both the remote control as well as the wall thermostat have to be replaced regularly and not many people do it. They run out of juice constantly. Sometimes they might have enough power in their cells to work the display and trick you into thinking they’re alright, but they lack the energy to function at their peak and fuel the functions that gadget was meant to perform. 


It’s important to find a proper berth or place to store your outside unit. Constant direct sunlight, as well as shrubbery, can be incredibly harmful to your device and might impede it from working properly. 


One of the most typical reasons why an air conditioner won’t work in Australia, as well as the rest of the world, is a dirty or clogged filter. It’s important to regularly clean your filter following the manufacturer’s instructions. Filters have to be cleaned, depending on usage, at least once a month. 


Drainage can get filthy or even blocked over time. Dirt, dust, lint, and a great deal of other detritus can impede its normal flow. If it’s choked, the drain pan will fill up, and water will start to drip onto the AC unit. 

When to call an expert 

If you’re not a trained and certified AC operator, some problems can’t be addressed without the proper knowledge. Brisbane College as well as some governmental institutions offer training in this field on account of its difficulty. Most AC operators in Australia have a certificate, earned after years of professional education, that corroborates their competence in the field.  

For the following repairs, it’s best to contact a qualified professional that has the experience, the know-how, and the right tools.

Refrigerant leaks 

Coolant starts to seep in the AC and the unit won’t perform properly. The location of the leak will affect the cost. It’s advised to have your AC scrutinized by a technician yearly to repair leaks before they become too big.  


Without a working capacitor, the motor that powers the unit won’t work. If the capacitor is compromised it needs to either be fixed or replaced, otherwise your compressor and fans won’t start up.  

Evaporator coils 

Evaporator coils take in heat in the air and send it back into the house as cold crips AC fog. This is done through a series of air ducts. The coils can become corroded over time and have to be inspected at least once every three years. 

Worn Contactor

In an AC unit there are multiple contactors. Each one of these apparatuses serves to regulate a device within your AC; compressor, blower motor, condenser fan motor, etc. If they need a repair it becomes difficult for the electrical current to jump-start any of these motors. 

 Condenser Coils

Condenser coils can normally be cleaned by a hose or a wet rag, but if they become too dirty they need specialized chemical cleaners that won’t corrode them.

These are just some of the many adjustments your air conditioner might need. Is it important to have your AC unit maintained properly and inspected regularly by certified technicians to care for your investment and preserve it in tip-top shape.
