    No trouble here. I use the medium setting for R-22 and the low setting for HFC's. What my manual says to do and I find it works.

    9 times out of 10 I found the leaks mid-section of the evaporator coil when it's a 410a system. Especially a Lennox coil.

    The new field piece is great for 410

    I have found the Amprobe UltraSonic to be very good for finding leaks in coils.

    I bought a cheap CPS detector and it works great on 410 but not so good on 22

    410a was specifically designed to be higher in pressure to environmentally safe, as opposed to R22. Now after stating the obvious, the reason there are so many more leaks in 410a systems is because of a design flaw that many manufacturer's didn't see coming. A condensating coil, such as an evap coil, with R410a running through copper tubing eats the copper away. THEN! The best part happens, the water mixes with the refrigerant and causes acidic properties that harm many known metals. It's pretty crazy but most brands have moved to aluminum evap coils. Or better yet, aluminum painted copper coils. lol

    I side tracked. My answer would be the good, old fashioned, soap and bubbles. I have found some leaks I would have completely overlooked without it. Messy but very successful.
