First Checks — What You Can Do Before Calling
Before calling for service, check these items: verify the thermostat is set to Cool mode with the temperature set below the current room temperature, replace the air filter if it is visibly dirty (a clogged filter can cause the indoor coil to freeze and block airflow), check the circuit breaker for both the indoor air handler and outdoor condenser unit, ensure the outdoor unit is not blocked by debris, vegetation, or stored items (at least 2 feet of clearance on all sides), and verify the outdoor disconnect switch near the condenser is in the ON position. If these checks do not resolve the problem, professional service is needed.
Common Causes When AC Runs But Does Not Cool
The two most common causes are a refrigerant leak and a failed compressor capacitor. A refrigerant leak causes the system to gradually lose cooling capacity — you may notice the air is cool but not cold, then warm, and eventually the system runs without any cooling at all. A failed capacitor prevents the compressor or outdoor fan from starting — you may hear a humming sound from the outdoor unit but no fan movement. Other causes include a dirty outdoor condenser coil that cannot reject heat, a failing compressor that runs but does not build pressure, a stuck reversing valve (on heat pump systems), an indoor blower motor that is not moving enough air across the coil, and a control board or thermostat that is not sending the correct signals.
Why Professional Diagnosis Matters
AC systems contain high-pressure refrigerant that requires specialized equipment to handle safely. Attempting to diagnose or repair refrigerant issues without proper training and tools is dangerous and can damage your system. Our technicians use digital gauges to measure system pressures, temperature probes to verify proper coil operation across the indoor and outdoor units, and leak detection equipment to locate refrigerant leaks. Accurate diagnosis prevents unnecessary part replacement and ensures the repair addresses the root cause, not just the symptom. ${site.parentFull} provides transparent pricing with a written estimate before any AC repair begins.
