Extreme heat is a dangerous force. Because of this, it’s important to stay cool when temperatures start to rise. One of the best ways to do that is to have a high-quality air conditioner.

But what if your unit isn’t working as it should? Is it time for an Aircon replacement? You don’t want to worry about your air conditioner malfunctioning when it’s scorching outside.

Keep reading to find out all the key signs that indicate when it’s time for an upgrade

1. Frequent Repairs

Repairs and regular maintenance are all part of owning AC systems. They’re expected.

But if you find that you’re needing to have it repaired more and more often, it’s time to think about a replacement.


Chances are that you’ll spend more time and money getting it repaired until it breaks down all the way. It’s easier and cheaper to replace it than to keep an old unit running.

2. Older Model

With new years come new discoveries and new ways of doing things. If your Air Conditioning unit is more than 10 years old, you’re missing out on all the latest technology.

Things like optimized energy efficiency and more compact styles are some of the benefits you’ll reap by getting an upgrade. Plus, it’s often good to replace old technology before it gets so old that it becomes a bigger problem.

3. Poor Air Flow

Do you feel the right temperature of air but at a fraction of the strength? Sometimes this problem is nothing more than a blocked passage or a filter that needs cleaning.

Other times the problem is a lot larger. Such as a fault with the compressor or even the air ducts themselves.

Aircon Airflow

Keeping cool is dependent on the consistent air flow of your air-con so be certain to find out the true origin of the problem. It could result in you needing to replace the unit. Calling a professional will pinpoint the issue for you.

4. Leaky Unit

It’s a normal occurrence to have some condensation gather around the unit as it works. That’s the nature of the beast. But the condensation should remain minimal.

There should never be any actual leaking of any kind from your machine. If you notice water collecting on or around the AC, it’s malfunctioning. It’s either unable to rid itself of the moisture or it’s leaking coolant.

Both are terrible problems that need dealing with right away. Excess water ruins furniture and flooring while exposed coolant poses a hazard risk for you and your family.

Oftentimes, the best way to fix such a problem is by replacing your Air Conditioning systems.

5. Unexpected Sounds

As you use your aircon throughout the years, you’ll come to recognize the different sounds it makes. Most of the time, it should run with very little noise at all. But churning through different cycles sometimes does produce noises as the machine works.

You know your system better than anyone. If there’s some strange noise catching your attention, something that doesn’t sound right, it’s time to call in a technician.

6. Spending More on Bills

A fluctuation in your energy bills during the change of seasons is common and normal. Ramping up the cooling as the temperature rises means a larger bill. It makes sense.

But the amount you pay on a regular basis also tells you the story of your air-con. If you notice you’re spending more and more at a significant rate, it’s possible the systems are breaking down.

It might be as simple as the unit aging and unable to work in an efficient manner or there’s a larger problem that needs addressing. Either way, it’s best to call someone to check it out before you end up spending far too much for too long.

7. Too Much Dust Collection

Air Conditioners not only control your home’s temperature, but they also filter your air as well. It’s one of the great benefits of these systems to have clean air no matter the time of year.

If you notice thick dust collections around the house, there’s a good chance your unit isn’t working right. It might be as simple as cleaning the air filters. But sometimes this is a big sign that it’s time to replace the unit altogether.

8. Bad Smells

There should never be any kind of smells coming from your air conditioner.

A strong and pungent smell indicates that a wire is burning out and needs replacing right away. It’s a serious fire hazard.

A musty smell is an indicator of mould growing inside of your unit. Breathing in mould is a dangerous problem and leads to many types of illnesses. When in doubt, call your local professionals and get your unit checked.

9. Fluctuating Temperatures

With your aircon unit, you decide the temperature you want. If you notice that the temperature in your home doesn’t correspond to your desired choice, this is a problem.

Aircon Temperature

No one wants hot air coming through the vents when trying to cool down the house. It’s dangerous to add even more hot air to an already scorching day.

10. Turns Itself Off

When the unit turns off once achieving the desired set temperature, that’s the unit working at optimal capacity. When it turns off after a few short minutes or if it struggles to turn on at all, this indicates a faulty machine.

You shouldn’t have to fight with your Air Conditioner in order to get the home temperatures you want.

Don’t Put Off a Necessary Air Conditioner Replacement

If your unit displays one or more of these symptoms, it’s time for an aircon replacement. It’s not a good idea to wait around and hope that things will get better.

A malfunctioning air conditioner is going to cost you more money in the long run if you don’t replace it when necessary. Plus, you and your family will end up feeling uncomfortable the entire time until the problem’s fixed.

Don’t spend those hot months in agony. Replace your unit as soon as possible.
