Failure rates of A/C systems

We are often asked which manufacturers are more reliable and which ones break down more often.


Unfortunately, there isn’t readily available data on the specific failure rates of Air Conditioning systems in the UK. Failure rates can vary depending on factors such as the model, installation quality, maintenance practices, environmental conditions and , of course, manufacturer.


While some studies or reports may provide insights into the reliability of certain brands or types of Air Conditioning systems, comprehensive and up-to-date data on failure rates across the entire UK market is generally not publicly available. We know some brands are worse than others; these are primarily sold via online appliance websites and the ‘cheap and cheerful’ brands imported from the Far East but ‘badged up’ in the UK, however there is no data to back that up, beyond personal experience.


Factors that contribute to the failure of Air Conditioning systems include:

1.      Poor installation: Incorrect installation can lead to performance issues, inefficiency and premature system failure.

2.      Lack of maintenance: Regular maintenance, such as cleaning filters, inspecting componentry and checking refrigerant levels, is essential to ensure optimal performance and longevity of Air Conditioning systems.

3.      Environmental Factors: Exposure to extreme temperatures, humidity, dust, and other environmental factors can affect the performance and reliability of Air Conditioning systems over time.

4.      Usage patterns: Heavy usage or improper operation of Air Conditioning systems can accelerate wear and tear and increase the likelihood of failure over time.


To minimise the risk of failure and maximise the lifespan of an Air Conditioning system, it’s crucial to invest in quality products, ensure proper installation by qualified professionals, adhere to recommended maintenance schedules, and address any issues promptly with timely repairs. Additionally, selecting a reputable manufacturer and choosing energy-efficient models can also contribute to reliability and performance.
