What is the correct way to flush an automotive A/C system?

Use closed-loop flushing with the OE-specified refrigerant and proper recovery/filtration to avoid contamination and protect seals and compressor oil.

Which A/C flush chemicals should I avoid?

Avoid alcohol, brake or carburetor cleaners, mineral spirits, penetrating oils, gasoline, and legacy refrigerants like R-11, R-22, or R-113.

Can using a non-approved flush void my compressor warranty?

Yes. Mixing non-approved solvents with compressor oil can alter viscosity, increase noise, reduce performance, and may void the compressor warranty.

What can I use to flush an automotive AC system?

Proper Flushing Techniques for Automotive A/C Systems

Most vehicle manufacturers recommend closed-loop flushing with air conditioning refrigerant as the flushing agent. This method avoids flush contamination since the refrigerant used is correct for the automotive A/C system.

Non-Approved Automotive A/C Flushes

Over the years, various non-approved liquids have been used to flush A/C systems. Common non-approved flushes include:

Alcohol
Brake Cleaner
Carburetor Cleaner
Mineral Spirits
Penetrating Oil
R-11, R-22, R-113
Gasoline

Risks of Using Non-Approved Flushes:

Damage to Rubber Components: Can harm sealing washers, compressor shaft seals, O-rings, and hoses.
Internal Compressor Damage: Alters the viscosity of the compressor oil when mixed, leading to performance issues, increased noise, and premature compressor failure. Using non-approved flushes can void the compressor warranty if failure occurs.
