You may need to reset your circuit breaker.
Incorrect setting on your thermostat or your thermostat may simply be OFF.

Dirty coil may have frozen your system

Dirty or blocked ductwork
Check your indoor unit to see (or hear) if the blower is running. Then go to different vents in your house to feel for airflow. If you do not feel any air, contact a certified repair person for duct cleaning services.
