I am a highly skilled and experienced home service professional. Recently, I received a call from a customer who was experiencing issues with their heating and cooling system. Upon inspection, I discovered that the collector pan was leaking water, which had been a problem for some time. The unit was also starting to rust out badly. I explained to the customer that this was a factory issue and not related to my work. I offered to replace the collector pan, but the customer declined, stating that they wanted to wait until the warranty expired. I informed the customer that the warranty would not cover the issue, and that they should contact the manufacturer directly to address the problem.
