Last year, we nearly voided our HVAC warranty without meaning to, but apparently, with some warranties, you have to have your HVAC plan correctly diagnosed within a particular period of time, but you also have to use particular heating plus cooling companies that are allowed by the warranty supplier. Every one of us knew that we needed to have some oil furnace service done on our electric oil furnace, but we weren’t aware that we had to use a particular HVAC serviceman to do all of the work for us… I guess we thought that as long as we were using a certified HVAC serviceman to do the tasks, it didn’t legitimately matter all that much. It turns out that we were definitely wrong, though, but thank goodness we started studying the nice print on our oil furnace paperwork when we did actually, because we only had two days before the warranty expired on us when we noticed it. Every one of us had been having our oil furnace inspected by a little family owned HVAC supplier based here in town, but the oil furnace paperwork said that we needed to use this other oil furnace service supplier from a couple of towns over. I called them up right away to make an appointment plus they were able to squeeze us in literally the day that our oil furnace warranty would have expired. I guess my advice to most people who buy an HVAC plan with a superb warranty is to make sure that you learn the nice print on the warranty so that you don’t accidentally void it all! I would have been so mad if we had ended up doing that, because a single of the reasons we bought that oil furnace was for the warranty that it had.
