We've reported on brands that 50 or more people responded to in our survey. Brands that got fewer responses tended to be smaller brands and not as widely owned.

Common faults

A low score means the brand is less likely to have that fault, according to people who responded to our survey. A high score means there were more reports of this fault for the brand.

Compare brands by commonly reported faults. Brands with a lower percent had fewer faults, so are a better choice.

The top performers

These brands scored best for reliability, satisfaction and service. This information gives you an indication of expected lifespan for various brands and can help when choosing a product.

Most reliable brands

Daikin, Mitsubishi Electric and Mitsubishi Heavy Industries

What we found

Overall, air conditioners are a relatively reliable product category with an average reliability score of 87%.
LG is more likely to have problems with filters and not enough heating / cooling.
Split and multi-split systems are more reliable than ducted systems. However, satisfaction scores are similar across types.

Warranty and your consumer rights

The stated manufacturer's warranty is one of the things to consider when buying an air conditioner. But it's just as important to understand your rights under Australian Consumer Law. You're entitled to a free repair, replacement or refund if your air conditioner develops a major fault within the first few years.

Your rights still stand even if the manufacturer's warranty has expired and you didn't buy an extended warranty.

FAQ

How did CHOICE get these results?

In 2023 we surveyed more than 950 people. We asked them about the performance and reliability of their air conditioner over the past 12 months. We then cut the data down by selecting air conditioners between 0-10 years old with a sample size of more than 50 people per brand, so we’re more confident that our results match real world experiences. Results were age standardised. See below for information on what this means.

What does age standardised mean?

To make sure the results aren't skewed by brands that may have recently come on the market, or that aren't making air conditioners anymore, we weigh results to an average distribution across the ten years. That means brands are compared more evenly.

How can I use this information?

This information tells you whether a brand is well regarded by people surveyed about customer satisfaction and reliability. Alongside our expert test results, this data can help you choose the best oven for your needs.

What does sample size mean?

The number of individual responses we received about a certain brand. For statistical accuracy we only included brands that had more than 50 responses.
