Detailed air conditioning system’s inspection needs to be done in every year even on your high end European Import Car – otherwise it might cost you more at the end.
At first, if your car’s A/C smells the system must be disinfected.
Your car air conditioning should be checked for proper operation and Freon charge at least once a year. Freon is very hard to contain in an automotive system. The reason is your air conditioning compressors operates at all different speeds due to engine RPM. The rest of the system is comprised of many dissimilar materials that expand and contract at different rates and along with the movement of the engine, this allows a minute amount of Freon to escape.
This is normal and that’s why the system should be checked for a low charge. You’re probably asking yourself does that mean I have a leak; probably not, at least not significantly.
Checking the amount of Freon in the system is very important because the Freon in the A/C system carries the refrigerant oil through the system to lubricate moving parts and seals. Insufficient Freon can damage the compressor, expansion valve and seals resulting in very costly repairs.
