re: HVAC Help Needed

The pessimist/curmudgeon in me thinks refrigerant leaks like this typically occur in the coil, but since it's under warranty he won't be able to "find" it for another year, at which point he'll do so and then recommend you replace your entire system.

But in regards to your question, it's 100% BS, but more than likely replacement refrigerant wouldn't be covered under a limited warranty.
