Air Conditioner Tune-Up Checklist

This is air conditioner tune-up checklist combining the detailed steps provided with general maintenance practices. This checklist ensures your AC system operates efficiently and effectively:

1. Outdoor Refrigerant Lines Inspection
   • Examine for physical damage that could cause leaks.
2. Refrigerant Line Insulation Check
   • Ensure proper insulation to prevent condensation and mold growth.
3. Indoor Unit Coil Cleaning
   • Verify the coil is clean, free of dirt and debris, for optimal efficiency.
4. Outdoor Unit Coil Inspection
   • Check for dirt and potential damage from external factors, including pet urine.
5. Air Filter Replacement
   • Confirm the right filter is used and changed regularly, every 2-3 months.
6. Indoor Blower Motor Examination
   • Check for dirt and ensure it is functioning properly to avoid overheating.
7. Overflow Safety Switch Test
   • Ensure it works correctly to prevent water damage from condensation issues.
8. Motor Capacitors Check
   • Verify capacitors are functional and have sufficient charge to avoid system failure.
9. Air Handler/Furnace Leak Inspection
   • Check for excessive leaks that decrease system efficiency.
10. Disconnect Box Inspection
    • Ensure no burnt wires or loose connections, and that it’s properly sealed.
11. Refrigerant Caps Tightness
    • Check for missing caps and ensure they’re tight to prevent refrigerant loss.
12. Thermostat Functionality Test
    • Confirm it is correctly calibrated, wired, and powered.
13. Bug and Rodent Damage Inspection
    • Check for any pest-related damage to electrical compartments.
14. Fan Blade Balance Check
    • Ensure blades are balanced to avoid unnecessary noise and component damage.
15. AC Unit Platform/Pad Inspection
    • Verify the platform is stable and level to support the unit.
16. Amperage Measurement
    • Check compressor and motor amperage for signs of overworking.
17. Reversing Valve Inspection (For Heat Pump Systems)
    • Ensure the valve functions correctly for both heating and cooling modes.
18. Refrigerant Levels Accuracy Check
    • Use a digital gauge to measure exact refrigerant levels for efficiency.
19. Contactor Inspection
    • Check for proper signal reception and transmission from the thermostat.
20. Temperature Split Measurement
    • Determine the temperature difference for potential system issues.

This comprehensive checklist covers essential aspects of AC maintenance to ensure your system remains in peak condition, providing efficient and reliable cooling.
