It is never a bad thing to leave it to the professionals. Inexperience can lead to more damage or risk of injury. You can always call A&E Factory Service (1-800-905-9505), Sears(1-800-469-4663), or local service man you can trust (servicemagic.com).

The only advantage I see to injection that you know that the dye is dispersed for sure...
I've had several instances where I installed a dye drier on a system known to have leak, came back a few days later, blacklite and goggles in hand, and found nothing. A quick press of the schrader valve reveals that the pellet/capsule has failed to rupture as designed...
otherwise, not much difference in the two. I find it difficult, in some well lit kitchens (natural light) to get it dark enough to see the uv and have to cover myself and the area in question with a heavy drop cloth to get a good read.

I have not used the stuff in ether form myself......................Will it find a leak in the low side??????...........If it takes over a year or more for the refrigerant to leak out, does the dye leak out in a measurable amount?????

The claim I have heard is it will reveal leaks as small as a 1/2 oz. A year...
works well for me ...when it ruptures :-)

Yes it will find a leak on the low side because when the compressor cycles off, the refrigerant on the high and low sides equilize. I have a picture of a leak from the suction tube on the evap. the leak is between the cap tube and suction line. ill try to post it from my phone. I put the yellow glasses over the lens of mu phone and shined the uv light as i took the picture.

thanks for the replies.. at sears we only use the dye dryers by whirlpool and i kinda wish we used the injection as it would help see the leak faster maybe even the same day...
