When Should Air Conditioners Be Replaced?

There are a few telltale signs that your old air conditioner needs to be replaced, like loud noises and bad smells. Any air conditioner over 10 years old, or with frequent problems, may be in need of replacement. 

It can be hard to tell if your air conditioner needs replacing or can still be fixed, so it’s always best to contact your local air conditioning specialist, Alliance Climate Control. 

Some signs your air con needs to be replaced include: 

Blowing Hot Air on Cold Function (Or Cold Air on Hot Function)

Blowing the wrong type of air is the most obvious sign that an air conditioner needs to be replaced.

If you’re feeling hot air coming from your system in the middle of summer when it’s supposed to be cooling you, that’s one of the first signs that a repair job isn’t going to cut it and you’re going to have to replace the entire system.

Loud Noises Coming From Your System

Sometimes a strange sound coming from your air conditioner is something that can be repaired, but if you hear loud screeching or grinding, that’s often something that can’t be repaired.

If you are constantly hearing loud noises coming from your air conditioner that sounds like they could be damaging the internals of your system, it’s very likely due for a replacement.

Significantly More Expensive Energy Bills

Getting higher bills from time to time is part of owning an air conditioner. You might have a particularly hot week and be using your air conditioner more, and that’s fairly normal.

However, if you’re noticing that your energy bills have spiked and are noticeably much higher than they used to be, that’s not normal at all. If your bills are higher than they have ever been, it’s time to look at getting a replacement AC unit.

Your Air Conditioner Is Turning Itself Off Randomly

Some air conditioning systems automatically turn themselves off when the desired room temperature has been reached. However, if your system is turning itself off randomly or is struggling to get to that ideal temperature, it could be short cycling, which is what happens when the system malfunctions and the cycle is unable to complete properly.

Short cycling is common in older air conditioning units and can put a lot of stress on your system. If you think your system is short-cycling, it’s important to contact a technician right away if you spot this symptom.

Minimal Air Flow & Poor Performance

If your air conditioning system just isn’t putting out enough air, that’s usually a good sign it’s on its way out.

Both split and ducted system air conditioners are generally quite consistent, so by the time your indoor unit is struggling to circulate air, it may be on its last legs. At the point where your older air conditioner isn’t running properly, it’s usually cheaper long-term to replace it.

Why Replace My Air Conditioner?

Replacing an older air conditioner is sometimes the better value solution.

There’s a common misconception that it’s always better to repair your air conditioner, and getting it replaced is wasteful and expensive.

Avoid Wasteful Repair Costs

After a certain point, continuing to repair an old air conditioning system is going to cost more than a replacement. As a unit continues to age, frequent repairs on an older air conditioning unit will be more more inconvenient and far more expensive. If your air con is past its expiry date, you'll spend more money on repairs than a full replacement over the next few years. On the other hand, completely replacing your air conditioner means you won't be dealing with constant repairs and maintenance.

Reduced Running Costs

You'll also be paying more to run an outdated air con unit than an up-to-date and energy-efficient model. When you install a replacement split system wall unit or ducted air con unit, you'll benefit from up-to-date features, including energy efficiency improvements that can save you money on your electricity bill.

Better Air Quality

Continuing to run an old air conditioner - whether it's a split or ducted system - is far less hygienic than replacing it. Even with new air filters, an old AC can circulate rust, bacteria and mould that it's no longer able to filter out. Upgrading to a new unit will mean you won't be breathing years of accumulated spores and debris. In addition, modern AC units come with sophisticated self cleaning and filtering systems, so you'll be breathing fresher and cleaner air for longer.

Better Performance

Upgrading your air conditioning won't just make your air flow feel stronger in comparison. Air conditioning technology is always improving, and upgrading to a modern model means you'll be experiencing the peak of modern climate solutions. No more missed spots and no more weak air flow, and new air conditioners are running quieter than ever.

zoning-icon

Up-To-Date Features

Throw out your old air conditioning remote, because upgrading to a new model lets you take advantage of all the features of modern air conditioners. Options include smart air conditioner control with a W-Fi enabled phone app, or new Intelligent Eye technology on select Daikin models, which will automatically turn off air flow after 20 minutes of not detecting a person in the room.

Better Air Con Solutions

Replacing an old air conditioner gives you the opportunity to reassess what you need from an air conditioner, and find out what options are on the market today. If you have more people living in your home than you did ten years ago, getting a different air conditioner is going to be far more convenient. Downsizing to a smaller air conditioner can save you hundreds on your electricity bill, alongside the fewer repair charges. On the other hand, if your current air con unit is undersized, you'll be paying excessive energy bills to keep your home cool. Interested in an in-home evaluation for AC replacement?

Replacing a Split System Air Conditioner

If you’ve had your air conditioner for more than ten years, or you’re noticing signs of wear, it might be time to replace your split system air conditioner. Split systems generally only last between 10 and 15 years, and even that can depend on installation quality, how heavily it’s used and the brand of air conditioner.

An old split system air conditioner is going to work less effectively, adding a sizable amount to every energy bill. In addition, the amount it will cost to replace it will quickly be surpassed by constant and expensive repair bills. Not only will you be costing yourself a small fortune, but you’ll still be stuck with an underperforming and unhygienic old wall air conditioner.

Here at Alliance Climate Control, we have years of experience with air conditioning wall unit replacements. We replace split system air conditioners all over NSW every single day, so you can feel confident our technicians will give you the right advice.

Should I Repair Or Replace
My Air Conditioner?

Many people assume it’s cheaper to repair an old air conditioner than replace it. However, this isn’t the case! Over time, you’ll spend more and more trying to repair and run an out-of-date air conditioning unit, and it will still need replacing as soon as the issues are no longer fixable. 

This comparison shows the difference between continuing to run an old air conditioning unit, compared to identical use with a new model.

Ducted Air Conditioner
Replacement

Contrary to popular belief, replacing a ducted air conditioning unit doesn’t require you to replace all your ductwork. At Alliance Climate Control, we can upgrade your ducted air conditioning unit or replace ductwork separately, offering the best value to our Sydney customers. 

Ductwork often doesn’t wear at the same rate as air conditioning units themselves. The best way to find out whether you can replace your central air con unit without replacing the ductwork is to book an inspection with Alliance Climate Control. 

Our technician can diagnose any issues with your ducted air conditioning unit, as well as performing a duct inspection. If there are holes and wear in your ductwork, this could be increasing energy consumption and your electricity bills, so a professional inspection is needed to check its condition. 

Your Alliance Climate Control technician will provide trusted advice on which option is most cost-effective. We’ll provide you with an obligation-free quote on replacing your air con unit, ductwork, or both parts of the central cooling system.

If you need a local technician who can provide you with affordable ducted air conditioning replacement, then look no further than the team here at Alliance Climate Control. For an obligation-free quote on ducted air conditioner replacement, call Alliance Climate Control today.

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!

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.

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.
Googie W.
The boys were so helpful, nothing was a trouble & they knew their stuff, very professional which made a great experience all round!
Garry K.
We are delighted with the level of service and the quality of the job. The technicians, Mitesh and Nick were fantastic

We have already referred one of our friends to Alliance
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!
Karim M.
Charles and Aaron arrived on time and were patient and professional while answering all of my questions. They provided clear, written quotes, explained exactly what was included and what wasn’t, and even suggested and implemented a solution on the same day for a problem that wasnt even part of the job they initially came out to do.
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.
Service Technician arrived within the advised block time. He carried out the required service very efficiently and provided a written report of the condition of all aspects of the A/C and cleaned all the filters, unit cover and the outdoor unit. Very satisfied with a thoroughly professional performance.

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

C W.
Had new AC units installed and an old one replaced. My experience with ACC and their team was fantastic from start to finish. The team that supported us included Liam, Vash, Will, B.J, Theo and Jun. Cannot thank them enough for being such a pleasure to work with. They were incredibly professional, good at what they do and showed great care in helping us with our installations. I would highly recommend ACC and this team! Thank you to the Team again!
Christopher W.
I recently had air conditioning installed by Alliance Climate Control and couldn’t be happier with the experience. From start to finish, the service was outstanding.

A special mention to Vy, Luan, and Eric, who did an exceptional job on the day. They were professional, punctual, and clearly took pride in their work. The installation was carried out efficiently, with great attention to detail, and they left the place clean and tidy afterward. They also took the time to explain everything clearly and made sure the system was running perfectly before they left.

Highly recommend Alliance Climate Control to anyone looking for quality workmanship and excellent customer service.
Julian W.
When our apartment’s 12-year old Daikin air-conditioning system broke down, we called a few A/C companies, including Alliance Climate Control (ACC). We were immediately impressed by ACC’s professionalism, promptness and very friendly office staff and service technicians. Shazin and Brandon did an excellent job diagnosing the system’s problems and providing a range of options as to its repair and on-going guarantee conditions. Once contracted, Yunis, Nico and their colleague (whose name, regrettably, I have misplaced), took great care in replacing the larger components on the building’s roof and replacing the five individual control panels in our apartment. Not a trivial job, given the roof accessibility in our building. Conner and Steven worked hard on a following, very hot day to diagnose and correct a tricky leak in the coolant pipe on the roof that runs to the apartment. With the pipe sealed, they commissioned and tested the system thoroughly. ACC kept us well informed throughout the entire process. We are very happy with ACC and have no hesitation in recommending them!

Frequently Asked Questions

What Is the Life Expectancy of an Air Conditioning Unit?

Depending on your air conditioning system, your air con could last anywhere from 10 to 20 years, and potentially even longer with consistent, professional maintenance. Heavy use and poor installation can also reduce this time frame. The best way to find out how long your air conditioning system will last, and how long until you’ll have to replace your current system, is to book an appointment with an air conditioning service.

Can You Replace Outside Air Conditioning Unit Without Replacing Inside Unit?

While it’s theoretically possible to replace the outdoor unit without replacing the indoor unit of your air conditioner, it’s usually best to replace the whole system at once. The outside and inside units of your air conditioner generally wear out at a similar rate, so you’ll get the best value when replacing both at once. Another factor is how old your air con system is. If you’ve had it for a few years, finding an outdoor unit that’s compatible with your existing indoor unit could be very difficult. 

If your indoor and outdoor units aren’t compatible, you may end up paying more in higher running costs and frequent maintenance than you stand to save by keeping the existing indoor unit. 

Can I Replace My Own Air Conditioning Unit?

We always advise against replacing your own air conditioning unit for both safety and warranty reasons. Almost every new air conditioner will state that if it’s not installed by a licensed technician, the warranty will be voided. Improper installation can also reduce the lifespan of your air conditioner considerably. 

If your air conditioner is so old that it needs to be replaced completely, it’s especially unsafe for anyone but a licensed professional to deal with. Old air conditioners in poor condition can not only be dangerous to try and remove, but can also be unhygienic and bad for your health. 

To protect your air con unit’s warranty and your safety, always have a licensed and reputable professional replace your air conditioning unit. As a bonus, you’ll receive expert advice on choosing a replacement air con unit to ensure you get the right size, avoiding excess energy bills from oversized and undersized units.
