Georgetown Context

Why This Matters in Georgetown TX

Georgetown's summer indoor temperatures can exceed 100°F within hours of AC failure — a genuine health risk for elderly residents, young children, and anyone with medical conditions. We prioritize no-start calls in our dispatch queue and carry capacitors, contactors, and thermostat batteries on every truck. Most Georgetown no-start calls are resolved within the first hour of arrival.

Diagnosis

Common Causes & What They Cost

Our Georgetown technicians diagnose these issues daily. Here's what we find most often.

⚡

Failed Capacitor (Most Common)

The start capacitor provides the initial jolt to start the compressor and outdoor fan motor. Capacitors fail frequently in Georgetown's heat — July and August are peak failure months. You may hear a click or hum before it dies completely.

$85–$150

🔌

Tripped Breaker or Blown Fuse

A tripped breaker or blown fuse in the outdoor disconnect box cuts power to the system. Check your panel first — if the breaker is tripped, reset it once. If it trips again immediately, call us (indicates a wiring issue, not just a trip).

$0 if just a trip; $150–$350 if underlying electrical issue

🌡️

Thermostat Issue

Dead batteries, a thermostat in lockout mode, or a Wi-Fi thermostat that lost its schedule can prevent the system from calling for cooling even when the outdoor temperature demands it.

$0–$180 (often just battery replacement or settings reset)

🔧

Failed Contactor

The contactor is the electrical switch that closes to power the compressor and outdoor fan when the thermostat calls for cooling. Contacts pit and weld over time — a failed contactor prevents the outdoor unit from starting.

$95–$175

💧

Float Switch Tripped (Water Overflow)

Georgetown's hard water causes condensate drain blockages. When the drain pan fills, a float switch shuts down the system completely. The system won't start again until the pan is drained and the drain is cleared.

$85–$150 drain service

Our Process

How We Diagnose It

Electrical Check First

We test for power at the outdoor disconnect, indoor air handler, and thermostat. No power = electrical or fuse issue. Power present = component failure.

Capacitor Test

We test capacitor microfarad rating. Capacitors test weak before failing completely — we replace on the spot if below spec.

Contactor Inspection

We visually inspect contactor contacts for pitting and measure voltage drop across closed contacts. A pitted contactor gets replaced immediately.

Thermostat & Controls Test

We verify thermostat operation, wiring continuity, and safety switch states (high pressure, low pressure, float switch). We clear any tripped safeties after resolving the root cause.

FAQ

Common Questions

Check: (1) thermostat is set to COOL, temperature is set below current room temp, (2) batteries in thermostat are fresh, (3) circuit breaker for AC is not tripped, (4) outdoor disconnect box is closed. If all four check out and the system still won't start, call us.

A capacitor replacement runs $85–$150 for parts and labor. This is the single most common Georgetown HVAC repair — we carry capacitors for all major brands on every truck and can replace same-day.

Clicking + humming = capacitor failure signature. The contactor is closing (click) and the compressor is trying to start (hum) but can't without the capacitor's starting boost. Don't keep trying — running against a failed capacitor can burn out the compressor motor windings.

You can reset the breaker once (if tripped). You can check and replace thermostat batteries. You can check that the outdoor disconnect box is fully seated. Beyond those three checks, leave diagnosis to a licensed technician — attempted repairs on electrical components can cause additional damage or injury.

Yes. Georgetown's indoor temperatures can exceed 100°F within 3–4 hours of AC failure in July. We classify no-start calls as priority dispatch during June–September. Call us immediately — don't wait until the next morning for an appointment.
