When Should You Replace or Repair Your Air Con: A Guide

Bulkhead Ducted Systems

1 – Frequent breakdowns

If your air-conditioning unit is constantly breaking down, it is probably time to replace it. Frequent breakdowns can be a sign of problems with the internal workings of the unit. It could also indicate that the unit has been exposed to vibration or physical damage. These can cause the internal parts of the unit to break down due to constant wear and tear. If this is the case, the unit will cost you more to repair than to replace.

2 – Age

Age is another indicator of when you should replace your air-conditioning unit.7years is the average lifespan of a split system air-conditioner unit, 10-15 years for a ducted system, but this varies depending on the model you have. If you have an older unit that is no longer efficient or doesn’t work as well, it is best to replace it before it conks out completely.

3 – Unusually high power bills

It is also a good idea to replace your air-conditioning unit if it is unusually expensive to run. Air conditioners can consume a lot of power and become more expensive to run if they are old. If you turn your air-conditioning unit on and your power bill suddenly increases dramatically, it is time to replace your unit. A new, more efficient unit will have a better energy star rating, and cost you less to run.

4 – Inconsistent cooling

If you notice that your air-conditioning unit isn’t cooling the house consistently, this is another sign that the unit needs to be replaced. A consistent cooling unit is important to maintain the comfort of your property and to keep the temperature at an appropriate level. If your unit isn’t keeping the room temperature consistent, it is most likely a sign that you need a replacement unit.


Air-conditioning units are a great addition to any home, but they need to be replaced from time to time. If your unit is old and doesn’t work as well as it used to, it might time to replace it with a newer model. It is not worth it to spend money to repair an old unit when it eventually breaks down again in a short period of time. Working with a reliable air conditioning service provider will go a long way in getting your air conditioning system back up and running again as it should.
