    Forget EZ Seal just use some caulking.

    Ran in to this beauty today.

    Previous tech decided the best course of action on a leaking microchannel condenser coil was to use some white caulking to seal her up.

    It didn't work to say the least.

    Poor customer was a few weeks out of warranty too.

    Ive seen caulking on roto locks before..... also seen pvc glue used to try and seal refrigerant leaks.....

    I wonder if epoxy would work...... I remember they used to sell epoxy for aluminum evaps in the supply houses.... back in the 12-22 and 502 days.

    That just looks like some of the birds we have here just left a deposit. I don't know about sealing a leak but it sure destroys your paint.

    What's this involve/how do you use it? I only see a picture of It, but no description on what it is exactly. I may give it a try to see how it works.

    I'll have to use mapp, as I only carry that and oxy-acetylene. Now I just need to find a supplier in Canada. I guess I can try York or maybe one of our local supply houses that carry Luxaire can get their hands on it.

    I would say more than half of the condenser coil leaks I find are on 4-5 year old microchannel coils. I think they're just crap to begin with.

    And the funny thing here is the same guy that installed it is the same guy that tried to fix it with caulking.

    The owner got fed up with him and called me.
