My 2001 intermittently doesn't blow cold so it seemingly has a refrigerant leak as it has no other issues with blowing, no weird noises etc but there is a slight damp smell just before the cooling cuts out. I was just going to go get one of those kits to top it up but the slight damp smell has got me thinking it is likely worth while having a shop find & fix the leak, vacuum the system and recharge it.

What do y'all think? What shops do the A/C work? Anyone have a guy in Houston?
