Why Is My Air Conditioner Running But Not Cooling Properly?

Your AC can run without cooling due to a clogged filter, dirty or blocked outdoor coil, low refrigerant from a leak, a frozen evaporator, or thermostat/airflow issues. Our licensed technicians in Lafayette and West Lafayette diagnose the cause, review upfront pricing, and complete agreed repairs on site, with 24/7 emergency service. Routine tune-ups (clean coils, measure refrigerant, tighten connections) help prevent this.

• Set thermostat to Cool and lower the setpoint below room temperature.
• Replace a dirty filter.
• Clear debris from the outdoor unit.
• Ensure supply and return vents are open.
