There could be many things wrong... 1. Dirty air filter in your furnace. (most common) 2. Low refrigerant level 3. Dirty indoor coil 4. Dirty outdoor coil If the outdoor unit is not running... 5. Tripped breaker for AC 6. Bad contactor 7. Bad capacitor 8. Locked compressor 9. Bad fan motor on AC These are the most common reasons. Hope this helps!
