Car AC Compressor Maintenance Guide

1. Regular AC System Use

Why? Running the AC periodically (even in winter) keeps seals lubricated and prevents refrigerant leaks.

Action: Turn on the AC for 10-15 minutes weekly, regardless of the season.

2. Check Refrigerant Levels

Why? Low refrigerant strains the compressor, causing overheating.

Signs of Low Refrigerant: Weak cooling, frequent cycling, or hissing noises.

Action: Have a professional check pressure levels and recharge if needed.

Warning: Never overcharge—it can damage the compressor.

3. Inspect for Leaks

Common Leak Points: Compressor seals, hoses, O-rings, and condenser.

Action:

Use a UV dye kit or electronic leak detector.

Replace worn O-rings and repair leaks immediately.

4. Maintain Proper Lubrication

Why? PAG or ester oil lubricates the compressor; low oil causes friction and failure.

Action:

When recharging refrigerant, ensure correct oil quantity is added.

If replacing the compressor, drain and measure old oil to match the new fill.

5. Clean the Condenser

Why? A clogged condenser restricts airflow, increasing pressure and overheating the compressor.

Action:

Remove debris (bugs, leaves, dirt) with compressed air or a soft brush.

Check for bent fins and straighten them carefully.

6. Belt and Clutch Inspection

Serpentine Belt: Cracks or slipping can cause poor compressor performance.

AC Clutch: Worn clutches may not engage, leading to no cooling.

Action:

Replace cracked or glazed belts.

Test clutch engagement (listen for a "click" when AC turns on).

7. Cabin Air Filter Replacement

Why? A dirty filter reduces airflow, forcing the AC to work harder.

Action: Replace the filter every 12,000–15,000 miles (or per your car’s manual).
