Air Conditioner Troubleshooting Guide 

By following the basic diagnostic approach that repair professionals use, you can determine if your air conditioner needs expert intervention before it breaks. First, examine your thermostat. Check to see if it is set on “cool” and if the temperate is set below the ambient temperature in your home. If it is, ensure that the electric breakers for the furnace, air handler, and AC are on. 

If there are no tripped breakers, the problem may lie in your thermostat, the wiring between the furnace and air handler, or the furnace and air handler control boards. If you do not think this is the case, you can also check your unit’s condensate pump to see if the reservoir is full. A new pump may be needed. 

When these possibilities are exhausted, focus on the outside unit. If the blower is running inside, but the fan on the outside unit won’t budge, you may have wiring or terminal repair issues. Before inspecting any wiring or controls, shut off the power to the unit to avoid system damage and bodily injury. If you shut off your outside unit and it does not restart, a reset button may do the trick. 

In many cases, a total loss of power to the outside unit means there are problems with the contactor or condenser fan motor. In some cases, your air conditioner may be low on refrigerant. Other possible challenges include too much ice or condensation on the unit and dirty parts. The AC filter, evaporator coil, and blower wheel need to be clean to operate effectively. 

Most of these scenarios will require that your air conditioner is serviced by a licensed and insured repair professional.
