What is a Blown Fuse?

An electrical fuse in the switchboard of your home is a safety device to protect against overloaded circuits when too many appliances are used at the same time.

Another more serious fault occurs when a live wire touches another live wire or metallic part of an appliance. This causes a short circuit and may result in an electrocution injury, or damage to your home from fire.

Electrical fuses to protect against these occurrences may be found in many different forms, ranging from a simple porcelain “plug-in” fuse, to more robust Residual Current Detectors otherwise known as RCD’s. These devices allow current to flow while everything is working normally. When a fault occurs, the flow of current is stopped until further action is taken.

A porcelain “plug-in” fuse, a low level protection device, comprises a very thin fuse wire connected between two terminals.

When an overload or short circuit fault occurs in an appliance or wiring circuit, enough heat is generated in the fuse wire to burn it through, preventing current flow until the fault is resolved and the fuse wire replaced

However, when a fault occurs, a plug-in fuse is slow to react taking time for the wire to burn through before protection is provided.In addition, most appliances operate at relatively high current flows, consequently the correct grade of fuse wire must be used.

Circuit breakers including many varieties of RCD’s are very rapid acting and much safer devices, providing greater protection for your family and your property. Being much more sensitive to changes in current flow caused by faulty circuits or appliances, such devices are able to react in milliseconds, much quicker than “plug-in” fuses and therefore provide greater protection.

Why did your Fuse Blow?

The main reason for a blown fuse is usually overloading a particular circuit when many appliances are operated at the same time, often on a “power board” or a multiple outlet adaptor on a single wall power point.

Another reason maybe if an appliance or power point outlet is subjected to moisture or water causing a short circuit. In this case, always turn off the power point and disconnect the appliance from the wall plug. If the fuse continues to “blow” or the circuit breaker needs to be reset again, call an Alliance Climate Control technician and request an emergency call out visit. Common causes of “blown fuses” or tripped circuit breakers are

Too many appliances used at the same time while connected to a single power outlet.
A fault in any appliance such as broken or exposed wires.
A broken or cracked housing in a wall or light switch, frequently a crackling sound is easily heard.
Water allowed to enter a wall mounted power point or perhaps dripping onto bare wires behind the wall.

We couldn’t be happier with the outstanding service from Alliance Climate Control! The team delivered a truly seamless installation of four split systems at our home (Service Ref. #101598) from start to finish.

A special commendation goes to Ahmad Maisam and Meedy for their exceptional leadership, organisation, and genuine care in addressing our needs. Their professionalism, clear communication, and attention to detail made the entire process smooth and stress-free.

The workmanship was excellent, the team was punctual and respectful of our home, and everything was left spotless at the end. Simply put—the best team ever. Highly recommended to anyone looking for top-tier air conditioning service!

Lina F.

Excellent service from start to finish..after contacting 2 prior air conditioner companies weren’t interested in doing the job , I found Alliance recommended by my friend Vicki .. highly recommend

Craig L.

We were very happy with the work undertaken by Dylan last week. He was very courteous and professional. He answered our questions very clearly and investigated the 2 issues we raised very thoroughly.

The team who attended my home last week to install a split system were impeccable - Gokhan, Louis and Rodrigo - as was Errol who attended to provide the initial quote and the office team when I called with some questions pre-installation. Everyone was helpful and professional. They set high expectations and delivered!

Christian B.

Andres from Alliance was excellent, professional and very clear. Our units are now operating perfectly and he detected a major issue and presented multiple solutions. Would recommend the service highly.

Sky S.

I couldn't be happier with the excellent service and clean provided by Emre.
He was punctual, thorough with his assessment of my aircon units and managed to identify the source of why my aircon has a mouldy smell. He was professional, knowledgeable and clear with his explanation of what can be the problems as well as recommending appropriate options to address the problems.
5/5 will call upon his services again if my aircons ever give me grief (though I doubt it with the level of servicing he performed).

Pete M.

Awesome company, awesome service. Quick reliable, very friendly and very informative.

Class act team! Love your work!

Gokhan and Louis did an amazing job installing my air conditioner! We had them install a split system in our bedroom, and couldn’t be happier

Their communication was excellent - explained the whole process and were very helpful and accommodating. The little things like helping to test different power mains to find the best configuration, the care they took to cover up and move my furniture, and the spotless cleaning job they did afterwards really set them apart. They even gave us a small gift bag at the end, which was a nice touch.

Highly recommended to go with this company, they are professionals through and through!

Nikki M.

I had a great experience from the first time I called with my initial enquiry until the completion of my installation. Excellent communication, customer care and follow up communications. I felt that I was being looked after throughout the entire experience. All of the technicians and tradesmen were very kind and extremely professional. I was kept updated throughout the installation. My place was left clean and tidy. I highly recommend this company - thanks!

Ana N.

Ivan, Brody, Miguel, B.J, Theo and Tim were amazing they kept everything clean and even without a lift they carried everything up and down. They finished in record time and I couldn't ask for a better team!

Martin C.

Very professional. Work completed as stated.

Dion O.

Great team of friendly, efficient guys. Highly recommended.

Chris D.

Jason arrived on time. I was very impressed with Jason’s performance and his knowledge of the system we had. Jason explained in detail what was done to the system and suggested the best way to clean the filter when it requires cleaning.

Emre was allocated to help with the aircon service for my apartment. I was very impressed with his professionalism. He is one of few dedicated technicians I have come across as knowledgeable who explained everything in details, patient with my questions, friendly, polite and on the whole, he did an amazing job. A very happy client. Thanks, Emre! Highly recommended!

Matthew K.

One of the few vendors who did an on-site inspection before install and took into account my requirements. Gokhan, Louis and Nicholas did a great job with an installation of a split system to an upstairs bedroom. Routed relatively well to avoid outside challenges. Left everything nice and clean afterwards.

Emma W.

Thank you Tommy, Kim and James for your professional courteous service this week. Very efficient and neat work. Explained options well and provided the best solutions for our awkward house.

Megan B.

Such a great team from Alliance just installed my new air con - life changing! Thanks to B.J., Theo, Tim, Emre and in the office Peter, T.K. and Will

Derek S.

We had two visits to fix our aircon Kody and Mitiesh and the problem was resolved satisfactorily. Both guys were very polite, friendly and explained the problem with the aircon and how it was fixed. Very impressive

Charles & Mo from Alliance were great, they did a difficult installation perfectly and cleaned up afterwards as well. Will be using their services again in the future.

Update - latest review for the Electrical Safety Inspection on 29/12/25 and Electrical Work on 07/01/26.

We are very impressed with Joshua, Vash and Mohammed. So, we are giving each one of them 5 stars. Joshua was very detailed and very systematic when he conducted the safety inspection last 29/12/25. Also, giving us practical tips about safety and to monitor the old power points. He also patiently explained the importance of getting the electrical system and smoke alarm up to code and all the things that needs to be replaced. He is also courteous in his behaviour and how he engages with us.

Vash and Mohammed arrived early for the electrical work on 07/01/26. These young blokes are very thorough, they know what they're doing. They worked as a team and non-stop for several hours. They are also impressive, respectful, and polite. Before they left, they double checked everything and even vacuumed the dining chairs and floor to keep thing tidy. We learned a lot from them and how to use electrical extensions safely.

These young men ( Joshua, Mohammed and Vash )will go far. They arrived neat, clean looking and ready to do the job. They have a high standard in workmanship, dedication and most importantly they have the right attitude about their work and how they treat us.

Kindly let them know that even though they might think they just did the electrical work. For us, they did more than that, they contributed to our health and safety.

Please, don’t stop inspiring these young men to continue developing their trade. They are the kind of professionals that our society needs. Thank you. Jennifer from Macquarie Fields.

Updated my review to include our recent service experience October 11, 2025 with Gabriel.

I want to share our recent experience with Gabriel, who provided a complete tune-up and service on our Fujitsu multi system last October 11, 2025. Overall, our experience was outstanding. My husband and I truly appreciate Gabriel’s dedication—his professionalism, expertise, and meticulous care stood out throughout the visit. He walked us through the air-conditioning health report, clearly explaining the tasks he completed and the performance of our air conditioner, while also offering practical and easy-to-follow maintenance suggestions that put our minds at ease.

Gabriel consistently demonstrates professionalism and a positive attitude toward his work, just as he did in January 2022. His respectful and polite manner made the entire process enjoyable. Thanks to Gabriel’s thorough service, we feel much more at ease knowing our air conditioner is in top condition and our home’s air quality is supporting a healthy lifestyle.

We are happy to recommend Gabriel to others, and we hope to see him again in another year or so. Thank you once again for your excellent service—Gabriel is truly deserving of 5 stars. Thank you, Gabriel.

On the 19th of Jan 2022 an inspection was conducted by Gabriel. He was punctual and did a thorough inspection. He came back with Bailey for the AC cleaning and tune up on the 21st of Jan as per agreement. We have rated both of them 5 stars for the following reasons and base on our observations. Punctuality, tidy in appearance and work, very knowledgable with their trade, well mannered, they did a meticulous job in servicing our AC. Most of all, they were both efficient because they worked as a team. We are a very happy customer. Thank you Gabriel and Bailey.

Gary W.

Alliance has done an amazing job from providing the solution , quoting and install by Vy and his team. The install was competed in one day with an even better outcome than originally designed. Well done to the entire Alliance Team and would highly recommend.

Russell O.

ACC was thorough and professional on their quote and their installation was all completed ahead of schedule. They made an effort to minimize the mess caused by the work and their cleaned up and hauled away all packaging. The AC has made our house a home!

Maria M.

Extremely impressed with Shaby, Michael and Benjamin from Alliance. Professional AC installation work, polite and friendly and very helpful. I would highly recommend these guys and the costumer service team from Alliance .

Helena M.

From the very beginning I knew I would receive good service from this company. The lady that answered the phone ( Kayley I believe) was very efficient in assessing what I needed and organising a supervisor to come in and arrange quote. That was Alex - he was very straightforward and a very good salesman!! The service itself was also straightforward with two techs coming in (Mitiesh and Nick) and they just got on with it while dealing with a very curious pet! Overall a very positive experience and I will be signing up with them for regular maintenance and refer the company for anyone who has a similar issue that I had. Thanks

Anne B.

We were very pleased with the whole process. Thank you.

William B.

Very proficient and easy Company to work with. Quality product and workmanship.

Maree S.

Had my ducted aircon serviced. Very happy with the professionalism from booking the appointment to service provided by Andre Galvis.

How to prevent Blown Fuses

Blown fuses or tripped circuit breakers are usually caused by overloading a circuit with too many appliances and can often be seen as heat discolouration of the power point or power board. In such cases, relocate some appliances to a different circuit or reduce which appliances are used at the same time.

In some cases, a broken or damaged wired entering an appliance will be seen to spark or “blacken” the area around the faulty wire entry when they are used. If this occurs, immediately turn off the power point and disconnect the appliance, making sure not to reconnect it until it has been checked by a professional and repaired. Alliance Climate Control technicians are available to visit your home to assess any appliance causing you concern. Your safety is our responsibility.

Water and electrical power should never be combined and any chance of moisture entering an electrical power outlet should be avoided. All power points in wet areas such as the bathroom or kitchen should be positioned well away from surfaces where water might gather, also any moisture leaking from a pipe behind a wall could have catastrophic effect if dripping onto a power point. This is usually a rare circumstance but it is important to seek professional advice should this occur.

Alliance Climate Control technicians are here to help and on call 24/7. They operate in radio controlled vans and can be at your Sydney address in a short time. Call them anytime.
