The End-of-Summer AC Inspection Checklist

Outdoor Unit Assessment

Your condenser needs special attention after months of continuous operation:

• Coil cleaning to remove summer debris, pollen, and cottonwood accumulation

• Fan blade inspection for balance issues and physical damage

• Refrigerant level verification to catch developing leaks

• Electrical connection tightening after thermal expansion/contraction cycles

• Compressor evaluation for signs of excessive wear or overheating

Indoor Component Checkup

Hidden issues often develop in your indoor unit during high-use months:

• Evaporator coil inspection for biological growth and debris accumulation

• Condensate system cleaning to prevent end-of-season overflow issues

• Blower wheel cleaning to remove buildup that affects airflow and balance

• Motor bearing lubrication if applicable to your system type

• Secondary drain line verification to ensure proper emergency drainage

Airflow Optimization

Restricted airflow causes numerous late-season problems:

• Comprehensive duct inspection for leaks that have developed from summer expansion/contraction

• Supply register balancing to ensure proper distribution to all areas

• Return air evaluation to verify adequate system breathing

• Filter replacement with consideration of increased late-summer allergen loads

• Blower speed assessment for proper air movement across the evaporator coil

System Control Verification

Your thermostat and control systems need evaluation after heavy summer use:

• Thermostat calibration check to ensure accurate temperature readings

• Anticipator adjustment if using older mechanical thermostats

• Battery replacement in applicable control devices

• Program verification to optimize for changing day length and temperature patterns

• WiFi connectivity confirmation for smart thermostats after summer storms
