AC Not Cooling? 5 Emergency Fixes
(And When to Call a Killeen Pro)

5 DIY Fixes to Try First

1. Check the Thermostat

Common Killeen issue: Power surges from Texas storms reset settings.

• Ensure it’s set to “Cool” and below room temp
• Replace batteries if display is blank
• When to call: If thermostat is unresponsive

2. Inspect Air Filters

Texas problem: Dust storms clog filters 3x faster than average.

When to call: If airflow is still weak after changing

3. Reset Circuit Breaker

Local insight: Fort Cavazos area experiences frequent power fluctuations.

1. Locate your electrical panel
2. Find the AC breaker (usually labeled)
3. Flip fully OFF, then ON

When to call: If breaker trips again immediately

4. Clear Condenser Unit

Killeen hazard: Fire ants love nesting in outdoor units.

• Remove leaves/debris within 2 feet
• Straighten bent fins with a fin comb
• When to call: If unit is damaged or making noises

5. Check for Ice Buildup

Texas paradox: Ice forms in 100°F weather when refrigerant is low.

• Turn system OFF immediately
• Let ice melt completely (4-6 hours)
• Change filter before restarting

When to call: Always – ice indicates serious issues

When DIY Isn’t Enough

Call a Killeen HVAC pro immediately if you notice:

• Burning smells (electrical fire risk)
• Water leaks (mold grows fast in Texas humidity)
• R-22 refrigerant (illegal to recharge – needs replacement)
