Don't lose your cool, beat the heat this summer with the right Air Conditioner main image

With another hot as hell Australian summer just around the corner, air conditioning is becoming less of a luxury and more of a basic need. 
Whilst most houses these days include some form of air conditioning, these units do have a lifetime, after which they either stop working or their performance drops while the power bill increases. 

A well maintained and regularly serviced air conditioner will last for quite some time, but their lifetime performance depends on how often you use it and the climate you live in. For instance, most cities in Australia easily hit the 40ºC mark, causing AC’s to work overtime to try and bring that hot external air temperature down to a comfortable level. When that happens, wear and tear on your unit is unavoidable. It is inevitable that your AC will fail eventually.

So how can you tell if your AC is due for an upgrade? 

Well, the obvious sign is it does not perform like how it used to when you first bought it. 

There are few key signs that you can look out for as they are the typical indications that your AC needs to be replaced.

1. The air coming out of the unit does not match the temperature it is set to:

This happens to a lot of older models. These models will continue to produce regular air level just like when you first bought it, but the air that is coming out may not be hot like the setting you chose, or it may not be as cold as to how you thought it would be. This is a clear sign that your compressor is most likely damaged, and unfortunately, it is rather an expensive and time-consuming job to get the compressor fixed.

You can try to inspect condensation drains or coils to see if there is anything obstructing the airflow and its temperature, however, if you experience an inconsistent temperature then it is not worth holding on to it. When replacing with a more updated AC, the long-term benefits such as cheaper running costs and better performance will make this a very worthwhile decision.

2. Diminishing AC Airflow:

You can easily feel there is a significant drop in air flow while the air conditioner is operating. If you can’t identify anything physically blocking the airflow, then chances are the AC’s compressor or fan is malfunctioning.

A healthy air conditioner should be able to keep your environment at a comfortable level in any circumstance. If you are still sweating in summer while your air conditioner is running or shivering in winter even though the heat setting is maxed out, then it is time to look for a new unit.

3. Increased Noise Levels Or Strange Smells:

Speaking from personal experience, there is nothing worse than sitting in your office with an old AC, enduring the outrageous rattling at the expense of comfort. A functioning air conditioner will occasionally make slightly louder noises when it cycles but most of the time it should be almost silent.

Similarly, if you are ever left in a situation where you have to endure the heat to have a peaceful sleep rather than dealing with a noisy old AC, then there is a problem.

The same goes for the smell. An air conditioner is not an essential oil diffuser or a scented spray. It should not produce any unpleasant smell at all. If at any time, you can sense any unusual smell when your AC is on then you will need to address the problem immediately.

An old malfunctioning air conditioner will contaminate the air that you’re breathing in. It is not a healthy environment to be in at all especially if you have children around. If the smell is not being caused by dirty filters (which you should clean out monthly), then it is time for an upgrade.

4. Leaks or Excess Moisture:

An AC unit should stay dry whether it is operating or not. A very minimal amount of condensation is acceptable due to the change in temperature but when you feel there is a sudden increase of moisture inside your home then it is worth to get someone to inspect your air conditioner.

Not getting your old AC fixed or replaced may save you a few hundred of dollars but in the long run, the excess moistures in your house can affect your respiration and immune system. Not only that it can also affect your house’s infrastructure if it is not treated fast enough.

5. Your Energy Bill Has Increased As Much As Australia’s Petrol Price:

The main reason people update their air conditioner is to bring the operating cost down. If you notice there is a spike in your monthly electricity bill than chances are something is not right with your AC unit.

You can always find a technician to take a closer look and fix the problem but most of the time it is not worth it. The labour cost is usually incredibly high and there is no guarantee how long it would last for. It generally would save time and money to just spend a bit and get a reliable AC unit with warranty for a peace of mind.

There are many financial and physical benefits to keep your AC up to date. A newer air conditioner is more likely to be more optimised which means it will save energy while producing a similar power output. An up to date, fully functional air conditioner means reduced energy cost, lower noise levels, improved air quality, & better living quality for you and the family.

Getting a new AC unit installed in your home will make your long, sweaty train ride home from work worth it. More importantly, there are no other ways to fight off the blazing heat in Australia.

6. Match Your Room With A Suitable AC Size:

One good tip to keep in mind if you ever shop for an air conditioner is to choose the right size air conditioner that can comfortably cool or heat your desired area.

The table below will assist you in matching air conditioner to your room size. This table is only a guide as other factors could affect the heating/cooling capability such as the ceiling height or insulation of a room.

Room Size To AC Unit 

Room size in m2 Cooling Capacity Heating Capacity
3m x3m = 9m2 2.5 KW 3.2 KW
5m x 5m = 25m2 3.5 KW 4.3 KW
6m x 5m = 30m2 3.5 - 5 KW 3.7 - 6 KW
8m x 5m = 40m2 5 - 6 KW 6 - 7.2 KW
9m x 5m = 45m2 6 - 7.1 KW 7.2 - 8 KW
10m x 5m = 50m2 7.1 - 8 KW 8 - 9 KW
