When should the refrigerant levels be checked in a system?

Checking refrigerant levels before starting the system is crucial for several reasons. First, it ensures that the system is operating efficiently from the get-go. Adequate refrigerant levels are necessary for the system to function properly, as low levels can lead to inadequate cooling and increased stress on the compressor, which could result in premature failure.

Additionally, checking the refrigerant before starting can help identify any potential leaks or other issues that may have occurred during installation or from past operation, ultimately preventing more significant problems from arising. Establishing a baseline for the refrigerant level prior to system operation aids in understanding its performance and can help in troubleshooting issues that might develop later.

While checking refrigerant levels during maintenance or when performance issues arise is also important, doing so before starting the system allows for proactive management and ensures the unit is ready to operate optimally right from the start.
