When assessing a cooling system after confirming that the thermostat is functioning properly, the next logical step is to verify the refrigerant levels. This is crucial because inadequate refrigerant can lead to inefficient cooling, compressor damage, and other issues within the system. Proper refrigerant levels ensure that the system can effectively absorb heat from inside the space and release it outside, thereby maintaining the desired temperatures.

If the refrigerant levels are low, it may indicate a leak or that the system was not charged correctly during installation or servicing, impacting the overall efficiency of the cooling system. Therefore, checking the refrigerant levels is a key step in troubleshooting and ensuring the system operates effectively.

While inspecting the compressor operation, checking the air filter condition, and confirming the power supply voltage are all important aspects of system maintenance, they would generally come after verifying the refrigerant levels, especially if the thermostat is functioning as intended.
