Yes, turn the AC off if it’s running but not cooling to prevent damage and wasted energy. The most common cause is a clogged filter or a frozen evaporator coil (the indoor cooling coil), which needs time to thaw before safe operation. If the coil is iced, switch the thermostat to Fan (On) to move air and speed thawing, but keep Cooling (Cool) off. Our technicians help homeowners throughout the Noblesville area with these exact summer breakdowns.
If you want quick checks before a visit:
- Confirm the thermostat is set to Cool and below room temperature.
- Replace a dirty air filter and make sure vents are open.
- Look for ice on the refrigerant lines or indoor coil panel.
- Check the breaker; if it trips again, leave the system off.
- Note any burning smells, water around the furnace, or rapid on-off cycling.
Do not chip ice or open sealed panels; schedule a professional diagnosis before restarting the AC.
