Q: White smoke coming from A/C coolant is low?

If you are referring to "smoke" coming from the dash vents when the a/c system is running, that is simply water vapor. The refrigerant is contained in a sealed system, although not quite as well sealed as a home or office a/c system. Consequently, over a period of years, there will be some "seepage" or loss of refrigerant from most auto a/c systems. On a relatively new car such as yours, the only way there will be a meaningful loss of refrigerant is if there is a leak. If cooling efficiency seems low, that is if the air provided is not really cold, the best thing to do is request that the system be tested. If you desire a leak inspection and state of charge inspection, simply request an空调系统检查响应认证的机械师将为您解决这一问题。如果您有其他疑问或疑虑，请随时重新接触万博体育入口因为我们一直在这里为您提供帮助。
