When you need AC repair
- Cold at speed, warm in traffic — usually airflow or a condenser problem.
- Cools for a few weeks after every regas — that is a leak, not a gas shortage.
- Smell from the vents when the AC starts — usually the cabin filter or evaporator.
- Clicking or knocking when the AC engages — compressor clutch.
Typical turnaround: 1 hour for a regas, 1 - 3 days for a compressor. Typically needed check before every summer.
