Why Is My Central Air Not Working? AC Troubleshooting Tips for Maize, Goddard & West Wichita

It’s a 100° Kansas day and your home feels like an oven. If you’re in Maize, Goddard, or West Wichita, you’re not alone. Here are the most common reasons a central AC stops blowing cold—and what to try before calling PD Plumbing Heating & Cooling.

Top 6 Reasons Why Your Central AC Isn’t Working

• Clogged Air Filter: Dirty filters choke airflow. Check monthly in summer and replace as needed.
• Tripped Breaker or Blown Fuse: Look for a tripped “AC” or “Furnace” breaker and reset once.
• Thermostat Issues: Confirm “Cool” mode, lower the setpoint 5°, and replace batteries if present.
• Dirty or Frozen Coils: Ice means airflow or refrigerant issues. Turn AC Off, fan On to thaw, then call.
• Blocked Outdoor Unit: Clear cottonwood, grass, mulch, or covers within 2–3 feet of the condenser.
• Low Refrigerant / Leak: Needs leak check and recharge by a licensed technician—don’t DIY.

DIY Troubleshooting Checklist

• ✅ Replace or clean your air filter
• ✅ Check the breaker panel for a tripped switch
• ✅ Make sure the thermostat is on “Cool” and set correctly
• ✅ Clear debris around the outdoor unit
• ✅ Use fan “On” to thaw a frozen indoor coil
• ✅ Still warm? Schedule AC service.
