Signs of a Refrigerant Leak in Your AC

Why This Matters

Refrigerant is your AC's lifeblood. When it leaks, cooling drops and compressors can fail.

Key Signs to Watch For

• Warm air from vents: Low refrigerant can't absorb heat.
• Longer cycles: System runs longer to reach temperature.
• Ice on lines: Frozen lines indicate low pressure.
• Hissing sounds: May indicate leak location.

What You Should Do

1. Don't ignore warm air — Usually indicates refrigerant issue.

2. Don't just 'top off' — Fix the leak.

3. Check warranty — Compressors may have 10-year warranties.

When to Call a Professional

Refrigerant handling requires EPA certification. Never attempt DIY. An HVAC technician locates and repairs leaks.
