    Detecting a leak

    What is the most economical way to detect a slow leak.
    I have a 1.5 ton split system with condensing unit on the roof.

    I'd recommend calling a hvac contractor & get him to use his electronic leak detector. It looks something like this.


    He's gonna charge you a service call & a fee for finding your leak. Sometimes they'll let that go towards the repair if its something like a evaporator. Just depends. If I were you I wouldnt even bother finding it, unless your planning on spending the money to have it fixed.

    Call a contractor, they will come out check electronically and with bubbles. They may need to boost the pressure in the system with nitrogen. And as hvachero indicated, if the leak is in a coil it likely will be unrepairable and the coil will have to be replaced.

    bubbles detect gross| large| bad leaks.

    small leaks by gas detection instruments, tuned for the specific gas.
    harvest rainwater,make SHADE,R75/50/30= roof/wall/floor, use HVAC mastic,caulk all wall seams!

    Have you applied for professional membership yet? I highly recommend it. You'll get some more detailed answers to many of the questions you've been posting.
    Perhaps you should have read the instructions before calling.
