What Is an AC Tune-Up? Understanding the HVAC Tech’s Checklist

Regular AC tune-ups are essential for maintaining the efficiency, performance, and longevity of your air conditioning system. But what exactly happens during an AC tune-up? Understanding the HVAC technician’s checklist can help you appreciate the importance of this service and ensure your AC is running smoothly when you need it most. In this blog, we’ll break down the comprehensive checklist that HVAC technicians follow during an AC tune-up.

1. Inspecting and Replacing Air Filters

Task: The technician will inspect the air filters and replace them if necessary.

Why It Matters: Clean air filters are crucial for proper airflow and efficient operation. Dirty filters can reduce efficiency and lead to system strain.

2. Cleaning the Condenser Coils

Task: The outdoor condenser coils are cleaned to remove dirt, debris, and other obstructions.

Why It Matters: Clean coils help the system release heat more effectively, which enhances cooling efficiency and prevents the system from overworking.

3. Checking the Thermostat Settings

Task: The thermostat is calibrated and checked for proper operation.

Why It Matters: Ensuring the thermostat is set correctly and functioning properly helps maintain comfortable indoor temperatures and improves energy efficiency.

4. Inspecting the Refrigerant Levels

Task: The technician will check the refrigerant levels and adjust them if necessary.

Why It Matters: Proper refrigerant levels are essential for efficient cooling. Low levels can indicate a leak, which needs to be addressed promptly.

5. Examining Electrical Components

Task: Electrical connections are tightened, and components such as capacitors and relays are inspected.

Why It Matters: Faulty electrical connections can lead to unsafe operation and reduce the lifespan of the system. Ensuring all connections are secure prevents potential failures.

6. Lubricating Moving Parts

Task: Moving parts like the motor and fans are lubricated to reduce friction.

Why It Matters: Proper lubrication prevents wear and tear, reduces energy consumption, and extends the life of the components.

7. Checking the Condensate Drain

Task: The condensate drain is inspected and cleared of any blockages.

Why It Matters: A blocked drain can cause water damage and increase humidity levels. Ensuring it’s clear prevents these issues.

8. Assessing the Ductwork

Task: Visible ductwork is inspected for leaks or blockages.

Why It Matters: Leaky ducts can significantly reduce efficiency by allowing cool air to escape. Proper ductwork ensures optimal airflow and cooling.

9. Testing System Controls

Task: The start cycle, operation, and shut-off sequence of the system are tested.

Why It Matters: Ensuring the system starts, runs, and shuts off correctly helps identify and prevent operational issues.

10. Evaluating Overall System Performance

Task: The technician will perform a complete system performance test to ensure everything is working together efficiently.

Why It Matters: A holistic performance check ensures all components are functioning properly, leading to improved efficiency and reliability.
