HVAC Breakdown Response in Georgetown, TX, System Dead or Won’t Start
A complete breakdown is different from an HVAC that runs but underperforms: nothing happens when the thermostat calls, the system is completely silent, or it powers off and will not restart. These failures require systematic diagnosis from the power supply through to the control board. ProAir Georgetown resolves complete breakdown calls within 60 minutes. A complete breakdown in a home with a baby or another vulnerable occupant and no cooling left running is exactly the kind of call we move to the front of the queue.

Match your symptoms below. Each points to a specific cause. We’ll confirm the exact issue on-site.
| What You’re Experiencing | What It Likely Means |
|---|---|
| Thermostat calls for heat or cooling, absolutely nothing happens | Complete electrical failure: transformer, contactor, or control board |
| Outdoor unit is completely silent, no hum, no fan, no click | Power supply issue, failed contactor, or seized compressor |
| System powers on briefly then shuts off completely | Safety switch trip: high-pressure, low-pressure, or thermal cutoff |
| Breaker trips immediately when HVAC circuit is reset | Hard electrical short: compressor winding or ground fault, do not keep resetting |
| Loud pop or bang followed by total system silence | Capacitor explosion or compressor valve failure, shut off power at the breaker |
Common Root Causes
Georgetown-specific causes based on 3,200+ service calls in Wolf Ranch, Sun City, Berry Creek, and Teravista homes.
Dual-Run Capacitor Failure
When the dual-run capacitor fails completely, neither the compressor nor the condenser fan can attempt to start. The system is entirely silent. This is the most common ‘dead system’ cause in Georgetown and a $150-$220 fix if addressed before repeated failed-start attempts damage the compressor.
Control Board or Transformer Failure
The control board is the brain of the HVAC system. Georgetown’s frequent lightning storms and power fluctuations cause more control board failures here than in most Texas cities. A failed transformer ($95-$160) or board ($280-$480) creates complete unresponsiveness.
Hard Electrical Short to Ground
A shorted compressor winding immediately trips the breaker on reset. Repeated resetting of a shorted compressor causes arc damage that escalates repair cost significantly. Reset once, leave it off, and call for diagnosis.
Tripped Safety Switch
High-pressure, low-pressure, and thermal limit switches create total shutdown when tripped. Unlike a tripped breaker, these will not reset automatically, the underlying cause (refrigerant issue, airflow restriction, or electrical fault) must be corrected first.
Lightning or Surge Event
A direct or near-miss lightning strike can destroy a control board, transformer, or compressor without any visible sign. Williamson County averages 60-80 lightning days per year. If your system went dead after a storm, always have a technician verify component integrity before restarting.
