I was bery pleased to get an appointment so quickly and the service technician arrived promptly after a heads up call that he was on his way. Once he arrived he tried to upsell me parts that I didn't need. I told him I thought the springs might be under
warranty and he said that they switched to a new system and he didn't have access to previous service history on his tablet. I told him to proceed as the work needed to be done but the warranty issue was still bothering me. I keep track of my expenses with Quicken and I was able to see that the previous service 4 1/2 years earlier was for 2 springs (plus other items) and that there was a 5 year warranty. After he completed the work I shared this additional info with him and he was now able to look up that same hsitory on his tablet. He called the office and they confirmed the work was under warranty and he removed the cost of one spring from the bill. After he left I gave this more thought and it seemed to me that since I had previously bought 2 springs, that were both under warranty, and I was encouraged to replace both springs, even though only one was broken, as he said that was standard practice and the other was likely to fail soon, that I shouldn't have to pay for either of the new springs. I called the office the next morning and the billing department agreed and I was credited for the second spring as well. So I never ended up having to pay $618 for 2 new springs, but it took persistence on my part to get both the technician and the office to take the necessary action.
