A/C System: lifespan, maintenance and replacement

Typical lifespan: 8–12 years.

Maintenance schedule

• Run A/C for a few minutes — Monthly (even in winter)
• Check for cool air output — Before summer
• Professional A/C service — Every 2–3 years

Signs it needs replacing

• Air isn't cold enough
• Strange noises when A/C is on
• Musty smell from vents
• Water leaking inside the cabin
• A/C cycles on and off rapidly

Tips

Don't use store-bought recharge kits blindly — overcharging damages the compressor. Get a professional diagnosis.
