Common AC Problems in San Marcos
System Overload from Heat
San Marcos summers regularly push past 100°F, forcing AC systems to run almost constantly. That leads to capacitor failures, weak compressors and frozen coils.
Dirty Coils & Filters
Central Texas dust and cedar pollen clog filters and coat condenser coils, reducing efficiency and triggering breakdowns. Regular maintenance prevents this.
Refrigerant Leaks
Constant cycling and temperature swings cause refrigerant line connections to develop slow leaks. We locate the leak, repair it and recharge to spec.
Electrical & Storm Damage
Lightning and power surges common to San Marcos can damage contactors, control boards and capacitors. We diagnose electrical faults safely and replace failed components.
