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.

Lily L.
We recently had a new ducted air conditioning system installed by Alliance Climate Control and couldn’t be happier with the experience. Liam was the first to attend our home when our 20-year-old system failed. He took the time to thoroughly assess the situation, explain our options clearly, and provide a very competitive quote. His friendly and professional approach made the whole process easy and stress-free from the start. On installation day, Vy and his team were great. They were punctual, efficient, and kept us informed throughout the entire process. They took care to keep our home clean and made sure everything was working perfectly before they left. Overall, the service was outstanding from start to finish. We really appreciated the professionalism, clear communication, and attention to detail. Highly recommend Alliance Climate Control to anyone looking for a reliable and high-quality air conditioning installation.

Guy M.
Great all-round service from Alliance! Communication was timely from Will and Chris in the office, and Liam, BJ, Theo and Nic were great to deal with for the job quote, service, and install. The install required access to my neighbour’s property, he also commented that they were incredibly polite—asking to move pots and putting everything back exactly as it was. Highly recommend!
Lance L.
Good, professional installation, very happy.
Innes P.
As usual, a pleasure to work with the team, installation went well with the team completing the work in the time they said they would, and following up when needed.

All very tidy too, with everything, even the old fans taken away - great work, thanks Charles and team!

We recently had our ducted air conditioning system replaced and couldn’t be happier with the experience. Their current google rating really reflects their level of service, From start to finish, the team delivered excellent customer service and made the whole process seamless.

Everyone we dealt with — VJ, Eric, Brody, Mosd, Harry K and Ionnaes — was friendly, knowledgeable, professional and always punctual. They were respectful of our home and took the time to explain everything clearly, which gave us a lot of confidence in their work.

We really appreciated the trusted advice provided throughout — it never felt like a sales push, just honest recommendations tailored to what we needed.

The operations were also very well organised. From the initial booking, through to installation and final payment, everything ran smoothly and on schedule.

Highly recommend this team if you’re looking for a reliable and professional air conditioning company.
M. G S.
The air conditioning service was outstanding. The technician arrived right on time, communicated clearly throughout the visit, and provided helpful information after the job was done. He serviced the equipment thoroughly and professionally. Couldn't be happier with the experience—highly recommended!

Update. March 2026

AGAIN! We had an outstanding experience with Alliance Climate Control, thanks to Gabriel & Nicolas.

They were extremely professional from start to finish; quickly diagnosed and resolved all of our air conditioning issues with confidence and precision. What really stood out was how informative they were, I was clearly explained the problems, the solutions, and how to prevent future issues.

The attention to detail, efficiency, and friendly approach made the entire process seamless. It’s rare to come across someone so knowledgeable and genuinely committed to great service.

A huge thank you to Gabriel and Nicolas; outstanding service.
Gail G.
Service is fabulous. Great customer service. Professional and very competent technician. I would recommend without hesitation.
Martin B.
Charles, James, Aden and JJ arrived on time and completed the installation in an exemplary professional manor. I would recommend the team to anyone. Cheers to you chaps.
Benjamin C.
I contacted Alliance Climate Control, due to leaking water from my air conditioner. I had Gabriel come to evaluate the condition, and he gave me quotes and explained options. He immediately scheduled the job through a phone call with the office. 2 weeks later, I had Emre and Luke come to my apartment to properly do a deep clean on my air conditioning system. They both did a fantastic job within 2 hours. After the AC is properly cleaned. It works perfectly and feels like new again. Really happy with the job they did. I think I'm going to do this every 12 months as they recommended.
Bill S.
The team led by Bokhan did an excellent job on the installation. They worked through the bad weather to get the job done, and were always ready to provide us feedback when needed. The instal team and the electrical team were very professional.
We would highly recommended Alliance Climate Control for their high quality work.
Helen C.
Dylan and Connor were punctual, professional and a pleasure to deal with. Painstaking in their work, they did an excellent job servicing my airconditioning unit.
Alison H.
Great service. Damon & Brendan arrived on time, worked quickly, explained everything, tidied up. Thank you!
Tim A.
Superb service - Ivan and hist team worked assiduously all afternoon to provide everything and more that I asked for - well beyond the call of duty! He and his team were receptive, polite and just got on with it. The best service I have ever had in fact.
Iva S.
Gokhan, Can and Niko have installed our new AC and removed the old one. Professional, kind, polite and very respectful. They cleaned all rubbish and packing materials from the works. They left the area clean and all the works have been done with good workmanship. Very careful with our belongings. Happy with the installation. Electrical works are still ongoing.

Edit to add the electrical installation- Mohamed and James were amazing. The job was very long, but the persevered and did a very nice neat conduit. They cleaned up after drilling and the cut offs- very neat work and great quality. Very polite and professional.
AC works ! Thank you for your services, would not hesitate to use ACC crews again.

I had a second job done by ACC - amazing electrician Mohammad and cannot fault his work. Always checking when things got tricky 😅 but we solved all the issues on the spot. He replaced our 24 years old main switch board and created 2 new outdoors el sockets. Neat, tidy, polite and very efficient. Even our cat liked him ☺️. Thank you for your service!
Helen C.
Excellent service, punctual and extremely thorough and helpful.
Michelle P.
I was happy with the service from Alliance through the whole process. Harry spent a alot of time at our house discussing the various options for aircon (ducted vs. Split systems) and the pros and cons of each - he even tried to find the manhole access to our roof. He was also very responsive to questions I had about the quote once we'd made a decision.
BJ and Carlos came for the install. They were very professional, did a good job of cleaning up afterwards, and spent time explaining the whole install process and how to use the systems once they had left.
I would use Alliance again for any further aircon installation. I was really happy with their service and the quality of the work.
Alborz R.
I had a fantastic experience with the entire team who installed my air conditioning system. From the initial coordination to the final installation, everything was handled professionally and smoothly.

A big thank you to BJ, Theo, Can, Matthew, Cara, Eric and Will — each of them was knowledgeable, friendly, and clearly took pride in their work. The team arrived on time, communicated clearly throughout the process, and left the place clean and tidy after the job was completed.

Highly recommend this team to anyone looking for reliable and professional air conditioning supply and installation. Couldn’t be happier with the result.

P.S. Andre returned to install the wooden aircon cover—fantastic job, great energy, and super efficient. Really appreciated it!
Rodney M.
Very professional. Great company. Efficient.
James T.
We are so very pleased with the installation of our new system. Kevin, Dragan and Ivan were so professional, thoughtful, with every aspect of the installation. Kevin’s instructions to me re the control pad were very clear with him constantly checking that I understood all aspect of the control panel. Their clean up and the way they left our home on completion was just perfect.
Kevin, Dragan and Ivan are a credit to your company, we feel very fortunate to have had three such competent team members of Alliance Climate Control carry out our requirements.
Pauline R.
I can't speak too highly of the service we received from Alliance. From first contact and ongoing attention from Cara and Luke in the office to the assessment stage with Steven, the service was courteous and efficient, answering all our questions without hesitation.
When it came to installation B.J. and Theo were very prompt and helpful, taking great care to ensure that we were well informed and happy about every stage , leaving us with written directions and a demonstration of how to use the controller.
We have no hesitation in highly recommending Alliance.
Nat C.
Thanks Aden and Ryan for your amazing work and leaving the place so tidy afterwards.
Mark C.
Stephen, Rahul and Alex were all very professional and did a fantastic job on our system. Highly recommended
Gael H.
Dylan phoned 30 minutes before arriving. He was clean, very efficient, knowledgeable and thorough. He patiently walked me through the timer process and left written directions. We kept him longer to answer questions. He did not tear out the door.

Susan D.
I was so lucky to get my annual service by Christian. He is a dream technician to work with. He was punctual, polite, accommodating, listened to my requests and fulfilled them all. Worked every minute whilst he was here, made photos and texted them to me, when I needed to know what condition the roof was in. His work was very clean, he did a very thorough job, got photos of "before and after". I couldn't be more satisfied with him, I'd like to get him back any time. I can recommend him to all your customers. Congratulations to the all your management who make excellent effort to pick the right people, who, in the end, just enhance the reputation of the company. Well done!
Ros R.
I have already given a feedback by phone that said how pleased I was with the teams efficiency & work ethics of Jonathon, Christian & Ca. They did a great job! Rosalyn
Alex B.
We had our system installed by Alliance a few years ago and everything about the experience was clear, professional with great results. Even now on the fixed price servicing, it’s predictably good, great value. I can’t recommend Alliance Climate Control enough. Thank you.

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.
