preferred leak detection method

dynamite196 on Mon June 22, 2009 9:05 PM User is offline

Refrigerant Type: r134a

Hi all, thanks to everyone here on the board we've narrowed my problem down to a leak (see the thread here: http://www.autoacforum.com/messageview.cfm?catid=2&threadid=20747).

Now the question is which method should I use, electric or uv? I'm just a DIY type so budget is a factor but at the same time I want to do the job right and if that means spending a little more that's fine. Adam was kind enough to suggest using one of the mastercool uv kits which looks promising but, after doing a little more research it seems that uv detection only works sometimes and that electric detection is the "way to go". So my question is this, do I have a pretty good chance of finding the leak using the uv kit, or would I be better off investing in one of the cheaper electric units? I probably have a good sized leak, maybe a can of refrigerant every month or so. Also, how long does the uv detection process take; are we talking an hour or two here or the whole afternoon? I'm pretty new to the a/c repair world but I like learning and it seems like this is the place to do it. Any help you can give me is greatly appreciated. thanks.

I would suggest the Tek-Mate electronic leak detector. Yes it cost a few more dollars but you can make it up by charging you pals a small fee to check their systems. A/C is not a difficult repair in most cases. But you do need a few tools to do the job correctly!

You could be waiting days or weeks to find a small leak with the UV system. It doesn't always show up right away on small leaks. The electronic "sniffers" work much better when the job is to find a leak then fix it.

I found having(and using to find a leak) both in the tool box is the way to go, i have the Tek-Mate and use UV dye between the two haven't been stumped yet..sometime small leaks are hard to sniff out too
i've found,so dye backs me up..

Thanks for the advice, so far I went and ordered up the mastercool pro uv kit (53351). If that doesn't point me in the right direction I'll go ahead and order up the sniffer too.

Daman makes a great point, sniffer to quickly pinpoint the leak, and dye for positive confirmation - way to go - especially when leak suspect is the evaporator.

We basically use an electronic leak detector in our shop. We do add dye as a back up for future leaks. No 53351 sold recently with ACkits.com but that's cool we will still be here to support the forum questions.
