Signs That You Need To Replace Your Air Conditioner

By ACR Solutions, February 9, 2023

A functioning air conditioner is essential to beating the Aussie summer heat! A good unit should be able to serve its purpose efficiently for years with proper maintenance; however, with age it may become less energy-efficient and effective and require more frequent repairs. Here are a few signs that you may need to replace your air conditioner:

Age Of Your Air Conditioner

The average lifespan of an air conditioner is around 10-15 years. If your air conditioner has been functioning for over a decade and is beginning to show signs of wear and tear, it may be time to consider a replacement. 

Increased Energy Usage

If you notice a sudden and consistent increase in your energy bills, it may indicate that your air conditioner is using more energy to perform its functions. Old air conditioners are often less energy-efficient and require more power to work properly, so it’ll likely work out more cost-effective in the long run to replace your air conditioner with a newer, more energy-efficient model.

Noisy Operation

A well-functioning air conditioner should operate quietly. If you notice unusual sounds such as rattling, screeching or grinding, it's time to get your unit checked by a professional. If the issue can’t be fixed or requires costly repairs, you can take that as a sign to consider replacing your air conditioner.

Poor Cooling Performance

An air conditioner failing to provide adequate cooling may have clogged filters, low refrigerant levels or other faulty components. Depending on the age and condition of the rest of the unit, a repair could be appropriate, however a professional may advise a replacement if the problem appears significant.

Frequent Repairs

If you’re having to fix your air conditioner multiple times in a year, it's probably not worth investing any more money into repairs. Instead, replace it with a new one that will function efficiently and save you money down the track. 

How To Properly Maintain Your Air Conditioner

Regular maintenance is crucial to extend the lifespan of your air conditioner as it helps to identify issues before they turn into major problems. 


  • Replace filters: Dirty filters can restrict airflow, reducing the cooling performance of your air conditioner. Clean or replace filters every month during the cooling season.
  • Clean the coils: Dust and debris can accumulate on the coils, reducing their efficiency. Clean the coils regularly to ensure proper functioning.
  • Check refrigerant levels: Low refrigerant levels can cause your air conditioner to work harder, using more energy and reducing its efficiency. Check the levels regularly and refill if necessary.
  • Lubricate moving parts: Moving parts such as fans and motors can become less efficient over time. Lubricating these parts regularly can help reduce friction and extend their lifespan.

Repairs Vs Replacement

It's important to consider the cost of repairs versus the cost of replacement. If the cost of repairs is close to 50% of the cost of a new air conditioner, it's probably not worth investing in repairs. Replacing your air conditioner with a new, energy-efficient model can save you money by reducing energy bills and the need for frequent repairs.
