If your air conditioner's indoor fan isn't working, first make sure that the switch hasn't been activated. If everything is OK, check the air filter. If it's locked, you might be able to fix it yourself. If there is ice on the evaporator coil and in the refrigerant lines, allow the ice to melt and check again if the fan is working.
If it doesn't work, the coil may freeze. A frozen coil requires a service call, as the technician may need to replace the contacts inside the fan relay, the fan belt, or even the motor itself. As summer approaches and flip flops become the usual weekend attire, just about everyone in Atlanta uses their air conditioners. And if you're the type who likes cool things indoors (think between 68 and 72 degrees), you're probably running the air conditioner a lot.
