Outdoors AC Leaking Oil

HVAC Condenser Coil Leak & Warranty

This is a quick lesson or reminder to anyone who just purchased a new AC system or new construction home. Most HVAC come with ten year warranty. But you need to register your unit with manufacturer for warranty to be valid.


Recently, our AC stopped cooling. Outside unit had visible oil leak. Apparently, oil is mixed in the refrigerant or coolant. Refrigerant evaporates leaving behind oil. So if you have oil leak, then you also have coolant leak. I figured that the fix would be simple as finding a small leaking part, replacing it, and then refilling refrigerant. Apparently our coil is leaking and that is essentially whole unit.

We called the company that installed HVAC originally. The guy initially scared me by saying that if we didn’t register the unit, then it probably is not under warranty and you cannot register now. It is only 3.5 years old unit.

Luckily, the company had registered it on their side, so all parts will be free. We still have to pay for labor which is still pretty high about $1100. But without warranty, it would have been another $1000 or so for the coil.
