FAQs for AC Problems
Why is my AC not working or cycling on and off?
Your system not turning on at all could signal a problem with your thermostat or a clogged air filter, although it’s possible that just a blown fuse or tripped circuit breaker is to blame.
Short-cycling is a common and typically more-serious AC malfunction that involves the system starting a cycle before quickly turning off but starting another cycle soon thereafter. The frequent and premature on/off cycling causes unnecessary wear and tear on internal components, leads to higher energy bills, and may be a symptom of ventilation system leaks, a defective thermostat, or other underlying problems.

If your system turns on, but the AC isn’t cooling to set temperatures, there may be a communication issue with your thermostat, or the unit could require a simple filter change. A refrigerant leak is another common cause of air conditioners running but not blowing cold air. A leak or low refrigerant levels should be tended to promptly before the air conditioner’s evaporator coils freeze and cause further complications.
- Water leaking and puddles forming
