What is an indication of a compressor that is not properly functioning?

High energy consumption is a clear indication of a compressor that is not functioning properly. When a compressor operates inefficiently, it requires more energy to achieve the desired cooling effect, leading to increased energy use. This can happen due to various issues, such as mechanical failures, refrigerant problems, or improper maintenance. A well-functioning compressor typically maintains energy consumption that correlates with its cooling load, but if it’s drawing excessive power, it suggests underlying issues.

Consistent temperature typically indicates that a system is functioning properly in terms of delivering the right cooling effect. Normal noise levels also suggest that the compressor is operating as expected, while low pressure could suggest issues but does not directly indicate poor functioning in the same way high energy consumption does. In the case of low pressure, it could reflect issues with refrigerant levels or other system failures but isn't as direct an indicator of overall compressor efficiency as high energy consumption. Therefore, high energy consumption is considered a primary sign of a compressor malfunction.
