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.

Your AC may run but not cool if the indoor blower is moving air while the outdoor unit, compressor, refrigerant circuit, thermostat, airflow, or electrical components are not working correctly. Common causes include a dirty filter, low refrigerant, frozen coil, dirty condenser coil, failed capacitor, outdoor unit issue, or compressor problem.
When the AC sounds like it is running but the home does not cool, the indoor fan may be moving air while another part of the cooling system is failing. The problem may be electrical, airflow-related, refrigerant-related, or connected to the outdoor unit.
If the indoor unit is blowing air but the outdoor condenser is not running, the system may not be removing heat from the home. This can be caused by a capacitor, contactor, breaker, motor, or compressor issue.
Low refrigerant can prevent the system from absorbing heat properly. It may also cause ice on the evaporator coil or refrigerant lines.
A clogged filter restricts airflow and reduces cooling performance. It can also contribute to frozen coils and longer run times.
If the evaporator coil freezes, the AC may continue running but stop cooling the home effectively. Frozen coils are often connected to airflow or refrigerant problems.
The outdoor coil releases heat from your home. If it is dirty or blocked by debris, the system can run but struggle to cool.
A weak capacitor or bad contactor can prevent the outdoor unit, compressor, or fan motor from starting correctly while the indoor blower still runs.
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 if the system is running but still not cooling after simple checks, or if you notice signs of a deeper issue.
The right repair depends on the diagnosis. Our technicians can test the thermostat, capacitor, contactor, fan motor, compressor, refrigerant pressures, airflow, coil condition, and system performance.
An AC that runs constantly without cooling can waste energy and place extra stress on the compressor, blower motor, outdoor fan motor, capacitor, and electrical components.
If your system keeps running but the home stays warm, schedule AC diagnostic service before the issue becomes more expensive.

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 the indoor blower runs but the outdoor unit does not, the issue may be a failed capacitor, bad contactor, tripped breaker, fan motor problem, wiring issue, or compressor problem.
Yes. Low refrigerant can prevent the system from absorbing heat properly and may cause poor cooling, long run times, frozen coils, or warm air from the vents.
If the system is frozen, tripping the breaker, blowing warm air for a long time, or the outdoor unit is not running, it is best to turn the system off and schedule AC diagnostic service.
Yes. A weak or failed capacitor can prevent the compressor or outdoor fan motor from starting, which can make the indoor unit run while the system does not cool properly.
