Q: AC leaking

asked by on

My AC doesn't work. I think it has a leak in the system.

Hi. While there is a small amount of refrigerant that will be lost by the AC system over the years, there is also a chance a leak may have developed. The system’s pressure needs to be checked and recharged to specifications. If the system is empty, there is definitely a leak. The AC system’s components will have to be inspected for an oily film buildup, which would indicate a leak. A leak detector may be necessary to locate the leak if the leak is hard to detect. You may want to enlist the help of a mechanic, like one from YourMechanic, who will have the necessary test equipment to inspect the AC system and recharge the AC if that is found to be the only problem.
