Service call for a/c not cooling on arrival the fuse at the condenser was checked and the fuse was ok. The thermostat is calling for cooling but nothing is run air handler is not running and condenser is also not running. The air handler is located downstairs in growlers bar. Two techs and an extension ladder is needed to access the air handler in the ceiling. Access is needed to air handler to further diagnose the issue further. This issue is not related to the fuse burning out. There is no voltage at the thermostat. No one was onsite at the time of the visit.
