When I bought my new furnace, I had a two-year unconditional warranty and a third year that was conditional. I added the extended warranty, hoping I would get service when I needed it, and it wouldn’t cost me as much money. I had five years of warranty, and nothing happened to the furnace. The servicing was done regularly, and the furnace was always in excellent condition. I was changing the air filters, and I even had my ductwork cleaned two years after having the furnace installed. It was two days after the extended warranty expired that I knew there was a problem with my furnace. I called the HVAC company, thinking I still had a few days on the warranty, and asked them to do service. They couldn’t send anyone to the house for three days. The three days ended up being nearly a week. The HVAC technician finally arrived and looked at the furnace. They were minor repairs, but I had to pay for them. I asked about the warranty, and he told me it had expired. It hadn’t expired when I called about the work on the furnace, and he shrugged. He said I would need to take that up with the HVAC company. The warranty had already expired when the HVAC technician got there. I paid the bill and was going to call the HVAC company, but my wife stayed my hand. She said to let it go. The bill was less than $100. She said we had enough money to pay the bill, and she didn’t think the work the HVAC tech had done, would be covered under the warranty.
