I need to get my A/C up and running again now that summer is here. One of my steel braided hoses ended up rubbing a hole in one of the A/C metal lines going into the dryer. So, it looks like I need a new dryer and some way to prevent the hose from rubbing. My question is, should I convert to r134 now? What experiences have any of you had with this conversion? What might i need and where might I get everything I need? Any help would be greatly appreciated.
