Common AC Problems We Fix in San Antonio

C.S.W. Power Solutions can diagnose AC problems such as warm air from vents, weak airflow, frequent cycling, frozen coils, clogged drains, water near the unit, thermostat failures, loud operation, electrical issues, and systems that run constantly without reaching the set temperature.

• Compressor failure — the most expensive AC repair; we diagnose before recommending replacement
• Refrigerant leaks — EPA-certified refrigerant handling, R-22 and R-410A systems
• Frozen evaporator coils — caused by low airflow, dirty filters, or refrigerant issues
• Thermostat malfunctions — wiring, calibration, and smart thermostat upgrades
• Blower motor problems — weak airflow, noisy operation, or complete motor failure
• Capacitor and contactor failure — common in San Antonio's high-heat environment
• Dirty or clogged condenser coils — reduces efficiency and causes overheating
• Drain line clogs — causes water damage and system shutdowns
• Electrical issues — tripped breakers, wiring faults, disconnect problems
• Ductwork leaks — losing conditioned air before it reaches your rooms

Need a Full AC Replacement Instead?

Some AC problems can be corrected with a repair, especially when the system is newer, parts are available, and the issue is isolated. Replacement may make more sense when the unit is older, inefficient, repeatedly failing, or no longer keeping up with the home. C.S.W. Power Solutions explains the repair findings and, when needed, can compare them with AC replacement options.
