I easily get sleepy of the constant upsell. It just wears me down to have a salesperson constantly haggle me to spend yet more currency with their business. Realizing that all dealers are in dealer to make currency, I still hate the add on stuff. I just got off the iPhone with our Heating plus A/C supplier. They called to confirm an Heating plus A/C service appointment. However, as they do each time, the lady wanted me to join the service program. This would include 2 service visits per year plus additional price incentives. I declined once again. And I guess I declined out of habit because I hate being upsold so much. Heating plus A/C service is something that I have consistently been a little bit hit plus miss on. Usually, the Heating plus A/C gets serviced once a year. But, there are easily times where I have missed a year. This got me to thinking so I did some quick online research. I wondered what the real value of Heating plus A/C service is. Well, I got some particularly interesting data on that particularly subject. I noted right away that of all Heating plus A/C service calls, 85 percent of them would have been caught while I was in routine seasonal service. That is a fairly shocking statistic when you guess about it. There was also the interesting impact on the longevity of an Heating plus A/C device due to respected service. Most modern Heating plus A/C units have a life span of nearly 15 years or longer in some cases. However, those numbers are based on those Heating plus A/C units getting seasonal service. Heating plus A/C units which did not acquire respected service ended up failing plus average of 6 years earlier. That did it for me. I called the nice lady right back plus signed us up for the seasonal service program.
