How Do I Know If My AC Needs a Regas?

- • Takes ages to cool down - Used to be quick, now takes 10+ minutes
- • Musty smell - Bacteria growth in the system (needs cleaning too)
- • AC clutch not engaging - May indicate low refrigerant
- • Visible oily residue - Around AC hoses indicates leak
How Often Does AC Need Regas?
Car AC systems naturally lose about 10-15% of refrigerant per year. Most systems need regas every:
- • 2-3 years for optimal cooling
- • 4-5 years maximum before performance noticeably drops
- • Immediately if cooling suddenly stops (indicates leak)
💡 Summer Tip
Book your AC service in spring (September-October) before the rush. Many workshops offer specials before summer hits, and you won't be stuck waiting when you need it most.
