When I needed an up-to-date furnace, I needed the same money-back guarantee I acquired from every other vendor I had purchased from, but i needed to make sure that if I didn’t enjoy the furnace, then they would refund our money or supply me another one. I said this to the HVAC service tech, and he gave me an odd look, and he told me he wasn’t sure that was possible, they offered me plenty of choices for a furnace, and a professional HVAC dealer would explain the main difference between every furnace and tell me which was the most efficient in heating and energy. The HVAC dealership would measure and take copious notes so they would get a furnace that suited our heating needs and those in efficiency that I asked for, but even though he gave me answers that would suit the everyday person, I still wasn’t cheerful. I wanted a guarantee that if I wasn’t pleased with how the furnace worked over the first sixty afternoons, I could return it. He eventually told me that he could not make that guarantee, and I would need to ask the HVAC dealership owner when he came to the house to discuss the up-to-date furnace with me. I’m not sure if I’ll follow through with the purchase from this corporation, especially if I don’t get some kind of guarantee. I don’t want to be stuck with a furnace for the next 20 or more years, if it isn’t exactly what I want. I’m thinking I’ll talk to several other HVAC companies in the area, and see if they’ll offer me some kind of guarantee. If they don’t, I’ll go with the best deal on the furnace I want.
