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.


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

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.

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.
