What happens if AC runs without a fan?

AC systems often face overheating compressors and reduced cooling efficiency without the outside fan. The outside fan in an AC unit dissipates heat from the condenser coil. If it stops working, the compressor may overheat, causing shutdowns or damage. Check the fan motor, capacitor, and wiring for faults.

How do Amish cool their homes without air conditioning?
