Now my A/C warranty is going to be void forever

The two of us were disappointed actually when one of our neighbors easily helped myself as well as others with a heating, ventilation, as well as AC issue. Neither of the two of us were entirely mad when someone offered to help with the issue. The neighbor claimed greatly a respected knowledge in all things dealing with ventilation, heating, as well as AC issues. He claimed to be certified in this specialty area, but he did not have a very good answer about the reason why he was working in a call center instead of the respected field of heating, ventilation, as well as AC services. The neighbor tried to tell the two of us that he no longer had much interest in heating, ventilation, as well as ac service. The two of us got a list of parts that the two of us would need in order to fix the issues with the heating, ventilation, as well as AC idea. Things seemed to be just fine after my neighbor left. The very next day, the heating, ventilation, as well as AC idea began to experience the strangest noises and frightening sounds. The neighbor was extremely busy as well as could not lend any assistance to this issue. The two of us were then forced to call on a local heating as well as AC Center to fix up the problem. We found out that the warranty would no longer be up for grabs due to the fact that we had off-market Parts on our system. How would either of us have known this?
