I haven't been on here in years, but want to celebrate with you guys.
So, I've been tracking down refrigerant leaks for a new customer all summer. A supermarket, of course...with 507. Also, I have another new customer who's had a leaking 404a system. I started with bubbles and a 'new school' leak detector and was somewhat successful but couldn't find all the leaks that I knew were still around. I ran into an old H10a on craigslist and talked the guy into selling to to me for $35 + $15 for shipping (in-state). He sent it and I put it to use right away. Ol' reliable pinpointed several leaks right away!!! I'm going to build a special padded crib for this baby and NEVER let 'er go. Thanks be to God and thanks be to the H10
