Trouble with Your AC? Let’s Unravel the Mystery
Fast Solutions, No Waiting
Even a minor AC issue can cause significant discomfort—especially in San Antonio’s relentless heat. If something feels off, here’s what might be happening:
Refrigerant Leaks
High heat strains your system, causing leaks that reduce cooling and blow warm air from vents.
Clogged Condensate Drains
Blocked drains can cause backups, leaks, and mold growth. We clear the way to prevent shutdowns.
Dirty Air Filters
Clogged filters restrict airflow, forcing your system to work harder, spiking energy bills, and causing coils to freeze.
Frozen Coils
Dirty filters or low refrigerant cause ice buildup that halts cooling and damages your system.
Thermostat/Electrical Issues
Faulty thermostats or electrical components lead to inconsistent cooling. We restore balance and reliability.
