How do I remove oil from my car's AC system?

The oil in my car’s AC system seemed low, so I topped it off—except now there’s oil all over the place, and I’m pretty sure I put too much in. How can I remove this oil?

Answer
Getting excess oil in your AC system is definitely frustrating, but solvable! Removing oil from a car AC may require a bit more knowledge, so don’t be afraid to take it to a mechanic or go through your car insurance claims process to get the job done right. If you’re feeling adventurous, however, you can follow these steps:
  • Flush the entire system, including solvent and compressed air
  • Vacuum out the excess oil with a wet-dry vac
  • Flush the system with rubbing alcohol
  • Put oil back in the system
A working air conditioner is vital to any car, so if you can’t fix this issue, your comprehensive coverage or extended warranty may cover it.
If you want to add comprehensive coverage to your policy for the best deal possible, check out the Jerry app—we’ll get you personalized quotes from top insurers, so that all you have to do is choose the plan that works best for you.
Best of luck with getting rid of that oil!
