Long Cooling Season

AC runs from April through October.

System Lifespan Is Shorter

Vegas AC units often last 8–12 years instead of 15–20.

Repair vs Replacement (Vegas Reality)

Replace your AC if:

• Repair exceeds 50% of replacement cost
• Unit is older than 10–12 years
• You’ve had repeated failures

Repair if:

• Issue is small
• System is relatively new

What To Do If Your AC Stops Working

In Las Vegas, acting fast can save you thousands.

Check Thermostat (Full Reset)

• Set to COOL
• Lower temp below room temp
• Replace batteries

Thermostat issues are often misdiagnosed as major failures

Use this quick fix guide: how to replace a thermostat battery correctly.

Check Breaker + Power

• Reset breaker once
• If it trips again → STOP

This often indicates:

• compressor failure
• electrical issue

Inspect Air Filter (Critical in Vegas)

• Remove filter
• If dirty → replace immediately

Dirty filters in Vegas:

• overheat system
• freeze coils
• cause shutdowns

Check Outdoor Unit (Desert Dust Problem)

• Check fan movement
• Listen for humming

If unit hums but doesn’t start → likely capacitor failure

Look for Ice or Water Leaks

• Ice → airflow or refrigerant issue
• Water → clogged drain line
