An air conditioner can stop cooling for many reasons. Some issues are simple, while others require an experienced HVAC technician.Dirty Air Filter
A clogged air filter is one of the most common causes of poor cooling. Restricted airflow forces your system to work harder and may even cause the evaporator coil to freeze.Replacing the filter every one to three months helps improve airflow, lowers energy bills, and extends equipment life. If replacing the filter doesn't restore cooling, call
+1 (844) 611-2488 for a complete inspection.Low Refrigerant Levels
Refrigerant doesn't get "used up." If your system is low, it usually means there's a leak.Signs include:
- Warm air from vents
- Ice on refrigerant lines
- Longer cooling cycles
- Higher utility bills
- Hissing sounds near the outdoor unit
Step-by-Step Troubleshooting Before Scheduling a Repair
Before assuming the system has failed, check these simple items.1. Verify the Thermostat
Make sure the thermostat is:- Set to Cool
- Below the current indoor temperature
- Running with fresh batteries if applicable
2. Inspect the Air Filter
Remove the filter and hold it toward a light source. If little light passes through, replace it.3. Check the Circuit Breaker
Sometimes the outdoor condenser loses power while the indoor blower continues operating.4. Look Around the Outdoor Unit
Remove leaves, grass, and debris around the condenser. Maintain at least two feet of clearance for proper airflow.If these steps don't solve the issue, contact
+1 (844) 611-2488 before a minor problem becomes a major repair.Common AC Problems in San Antonio Homes
San Antonio's long cooling season places significant demand on HVAC equipment.Frozen Evaporator Coil
A frozen coil blocks airflow and reduces cooling performance. Common causes include dirty filters, airflow restrictions, or refrigerant leaks.Dirty Condenser Coil
Outdoor coils collect dust, cottonwood, pollen, and dirt that reduce heat transfer efficiency.Failing Capacitor
A weak capacitor may prevent the compressor or fan from starting correctly.Symptoms include:
- Humming sounds
- Delayed startup
- Warm air
- System frequently shutting off
Compressor Problems
The compressor is the heart of the cooling system. If it begins failing, cooling capacity drops significantly.Professional diagnostics can determine whether repair or replacement is the better investment. Call
