If your AC is running but not cooling in Spring, TX, the problem may be caused by the outdoor unit not running, low refrigerant, a dirty air filter, frozen evaporator coil, dirty condenser coil, weak capacitor, thermostat issue, restricted airflow, or compressor trouble.

A running indoor fan does not prove the system is actively cooling. The thermostat may be set to fan ON without a cooling call, or an airflow, outdoor-unit, electrical or refrigerant problem may be reducing cooling. Check thermostat settings and an accessible filter first. A technician must test the system to distinguish these causes.
When the AC sounds like it is running but the home does not cool, first distinguish indoor fan operation from an active cooling call. Fan ON can circulate air between cooling cycles. If cooling is requested and the room stays warm, thermostat, airflow, outdoor-unit, electrical or refrigerant problems may need diagnosis; the symptom alone does not identify a failed component.
During a cooling call, an indoor blower running while the outdoor unit remains off may point to power, controls, a safety lockout, applicable start components, motor or compressor problems. Outdoor operation can also vary with equipment controls; a technician should verify the reason.
Low refrigerant can reduce heat absorption and may contribute to icing. Refrigerant is not normally consumed in a sealed system. If charge is low, a technician should investigate leakage or an incorrect previous charge rather than assume adding refrigerant alone resolves the cause.
A clogged filter restricts airflow and reduces cooling performance. It can also contribute to frozen coils and longer run times.
Ice on the evaporator coil can restrict airflow and reduce cooling. Airflow and refrigerant problems are possible causes. Turn cooling off, allow it to thaw and schedule diagnosis; do not chip ice or remove equipment panels.
The outdoor coil releases heat from your home. If it is dirty or blocked by debris, the system can run but struggle to cool.
On equipment that uses these components, a failed capacitor or contactor can prevent the compressor or outdoor fan from operating while the indoor blower runs. Some systems use different motor and control designs. Electrical testing and repairs require a qualified professional.
Thermostat settings, wiring issues, control board problems, or low-voltage failures can cause the system to run incorrectly or fail to call for cooling properly.
If the compressor is not starting or is failing, the AC may run but not cool. Compressor issues require professional diagnosis before repair or replacement decisions.
If your AC is running but not cooling, there are a few safe checks you can do before scheduling service.
Call Expo Heating & Cooling Inc if the system is running but still not cooling after simple checks, or if you notice signs of a deeper issue.
Stop operation if you notice burning odor, electrical buzzing or water near electrical equipment, if you can do so safely. Leave a tripped breaker tripped and request qualified service. For smoke or fire, leave the area and call 911.
The right repair depends on the findings. A technician may evaluate thermostat operation, airflow, coil condition, refrigerant performance and applicable electrical components. Testing depends on the symptoms and equipment; no-start symptoms alone do not establish compressor failure.
Long periods of operation without useful cooling can waste energy. Some faults can also damage equipment if operation continues, so persistent poor cooling deserves diagnosis.
If the system is frozen, repeatedly trips a breaker, or makes unusual electrical noises, stop operation and arrange professional service. Otherwise, begin with the safe checks above and schedule diagnosis if cooling does not improve.

Your AC may be running but not cooling because of a dirty air filter, low refrigerant, frozen evaporator coil, dirty condenser coil, failed capacitor, outdoor unit problem, thermostat issue, weak airflow, or compressor problem.
If cooling is requested but the outdoor unit does not operate, possible causes include loss of power, controls, safety lockouts, applicable start components, wiring, motor or compressor problems. If the thermostat fan is set to ON, the indoor blower may also run between normal cooling cycles.
Yes. Low refrigerant can reduce cooling and may contribute to long run times or icing. A technician should verify charge under appropriate operating conditions and investigate leakage or an incorrect previous charge; refrigerant is not normally consumed in a sealed system.
Turn cooling off if ice is visible. Stop operation for unusual electrical noises, burning odor or persistent no-start symptoms, if you can do so safely. Leave a tripped breaker tripped and arrange qualified service. For ordinary poor cooling without these warning signs, check thermostat settings and an accessible filter, then schedule diagnosis if the problem continues.
Yes, on equipment that uses a capacitor for the affected motor. A failed capacitor can prevent the compressor or outdoor fan from operating while the indoor blower runs. Similar symptoms can have other causes, and some systems use different designs. A qualified technician must test the equipment.
Yes. Expo Heating & Cooling Inc diagnoses and repairs AC systems that run but do not cool, including capacitor problems, refrigerant issues, frozen coils, thermostat problems, airflow restrictions, outdoor unit issues, and compressor concerns.
