Maintaining a functional air conditioning (AC) system in Phoenix, AZ, is essential for indoor comfort, especially during scorching summer months. At American Home Water & Air, we understand that AC issues can arise unexpectedly. This article provides troubleshooting tips for common AC problems to help homeowners identify and potentially resolve issues before they escalate, ensuring continued comfort and efficiency.

Common AC Problems and Troubleshooting Tips

Learn how to troubleshoot these common AC issues:

1. AC Not Turning On

Issue: Your AC unit fails to start when the thermostat is set to cool.


  • Check Thermostat: Ensure the thermostat is set to cool and set below the current room temperature.
  • Inspect Power Supply: Verify the AC unit is receiving power. Check circuit breakers and reset if necessary.
2. Weak Airflow

Issue: The AC system is running, but airflow from vents is weak or reduced.


  • Replace Air Filter: A clogged air filter restricts airflow. Replace the filter if dirty.
  • Check Vents and Registers: Ensure vents and registers are open and unobstructed for proper airflow.
3. Uneven Cooling

Issue: Some rooms or areas in your home are cooler than others.


  • Inspect Air Ducts: Check for leaks, gaps, or blockages in ductwork. Seal leaks or consider duct sealing services.
  • Adjust Dampers: If your home has zoning, adjust dampers to balance airflow to different zones.
4. AC Cycling Frequently (Short Cycling)

Issue: The AC unit turns on and off frequently, often in short cycles.


  • Check Thermostat Placement: Ensure the thermostat is not exposed to direct sunlight or near heat sources, which can affect temperature readings.
  • Inspect Air Filter: A dirty filter can cause short cycling. Replace the filter if necessary.
5. Strange Noises

Issue: Unusual sounds such as grinding, rattling, or squealing coming from the AC unit.


  • Inspect Outdoor Unit: Check for debris around the outdoor unit that may be causing vibrations or obstructing moving parts.
  • Schedule Maintenance: Contact American Home Water & Air for professional inspection and repairs if noise persists.
6. AC Leaking Water

Issue: Water pooling around the AC unit or water leaks indoors.


  • Inspect Condensate Drain: Clear clogs or blockages in the condensate drain line. Use a mixture of bleach and water to clean the drain pipe.
7. Frozen Evaporator Coils

Issue: Ice buildup on the indoor evaporator coils.


  • Check Airflow: Insufficient airflow due to dirty filters or blocked vents can cause coils to freeze. Replace filters and ensure vents are open.

Benefits of Timely AC Troubleshooting and Maintenance

Identifying and addressing AC problems promptly offers several benefits:

  • Prevent Costly Repairs: Early intervention prevents minor issues from escalating into costly repairs.
  • Ensure Efficiency: Properly maintained AC systems operate efficiently, lowering energy bills.
