Going on the assumption that an Heating plus A/C warranty was pretty much like any kind of warranty was my first error.
No, absolutely it was my second mistake.
The first mistake was not realizing that I only had 90 days to register the warranty on my current Heating plus A/C equipment. After that the Heating plus A/C warranty wasn’t gone. Thankfully for me, I have a spouse who pays attention to the Heating plus A/C corporation about what we need to do. So I got away with 1 there, however that streak wouldn’t continue. About multiple years into having the Heating plus A/C installed, I observed there was some soot or something around 1 spot on the gas furnace. This was observed because I thought the gas furnace was acting a bit funny. It seemed like it was running more than it should given the temperature outside. So when I saw that streak I took off the panel to discover some sort of switch or something which looked dirty plus burned out. My noggin said, upgrade it. And that’s exactly what I did. But, I used a part from the hardware store plus not a factory piece. Had I read my Heating plus A/C warranty, I would have known that me working on the Heating plus A/C plus using non OEM parts would void the warranty. When the gas furnace ultimately broke down I had to pay for some truly lavish service because there was no more warranty on the furnace due to my actions. So do yourself a favor and make sure you study plus understand every word in the warranty for your Heating plus A/C equipment.
