Thread: A/C cold but not as cold as some?

The gas maybe slightly down. One reason for this is that most people don't run their A/C over winter.
The compressor for the A/C has a crankshaft which is turned by the fan belt. The shaft seal on the crankshaft which separates the A/C system from the atmosphere works on a wet seal principle..That is, the seal must remain constantly wet with refrigeration oil from inside the A/C system. When the seal does not have oil splashed on it regularly from the running compressor, it goes dry and this allows refrigerant to escape from the A/C system. As soon as you run the A/C, the seal re-wets itself and self repairs the leak thus allowing your A/C to keep running but with reduced cooling capacity.
This is a very common problem for most car A/C that is not running cold enough
999 out of 1000 times, this is the only problem if your A/C is not cold enough.
If the gas has leaked from the system this way, you can stop the problem in future by running your A/C once a week for ten minutes(rain, hail or shine).
Where the compressor is mounted has no bearing on on its efficiency. I could give you the reasons why, but then you may as well go and get your trade papers.
Just get it checked.
