    Rust at AC line connection to coil

    Quick question..... my clients just had an inspection done on a property yesterday and we got the report back today.

    The inspector said there was "rusting at the AC line connection to the coil."

    what will happen if this is left alone?

    rust around a coil in NC is noted because its synonymous with refrigerant leaks. home inspector's "have" to find something wrong. the don't go into great detail on HVAC equipment. to have the HVAC equipment checked properly call a local company. they can tell you if this "rust" is an issue or a inspector thats "finding" something wrong

    It's probably missing the insulation on that one point. As stated above rusting is the first thing you notice when you find a leak.....If I'm looking for a leak rust/oil is the first thing I look for on quick inspection to get a general idea where to use the leak detector.

    LMAO sounds like a good recipe to me! My fiance was a HVAC tech and explained the whole thing to me..... Looks like water isn't getting out....duh!.... I also checked some web sites that explain more about what could be happening inside and making it rust where the freon pipes inter the unit.

    Copper doesn't rust, aluminum doesn't rust, the galvanized end plates rust. So the rusting and leaking are related. How? Thanks in advance.

    He's probably not seeing actual rust but corrosion and calling it rust. Although the two are not far from each other.

    You said "where the freon lines enter the unit". In that case it's probably just the sheet metal rusting around the holes that the pipes pass through. The sheet metal is getting wet due to air leakage around the pipes or due to the suction line not being insulated well at that point. A little bit of silicone caulk to seal the air leaks will probably prevent further rusting of the cabinet or cover. Rust accumulating on the pipes isn't damaging to them, it just stains them.

    If it's left alone, then the rusting of the sheet metal will continue. Eventually the panel will rust through and the air leakage will get worse. I've only seen that happen on rare occasions though. Usually the unit needs replacing long before the sheet metal falls apart.
