One tip for troubleshooting an air conditioner is to begin by inspecting the thermostat to ensure it is functioning properly. Ruling out a faulty thermostat can make other problems easier to identify. Another tip is to ensure the circuit breaker has not been tripped. Further tips include ensuring the condenser fan is spinning and checking air flow around interior vents.
There are numerous problems that can interfere with the operation of an air conditioning unit. Basic troubleshooting efforts consist of ensuring the HVAC system is getting electrical power and thermostat and controls are properly set. Helpful tips for troubleshooting a problem may also include inspecting and changing the filter, cleaning the outdoor compressor and ensuring the system has sufficient coolant.
Troubleshooting units that are operational but suffering from impaired performance may involve inspection and lubrication of the condenser motor, pulley and belt. Replacing components that may be suffering from excess wear or adjusting belt tension can remedy a number of common issues. The presence of standing water or excess moisture on or around the unit often indicates a water leak. Inspecting and testing the condenser pump or removing ice build-ups that may be blocking tubes may also be parts of the troubleshooting process.
