When the HVAC technician was at the house, he told us there were some problems with the furnace.
He was fairly certain it would last us this year, but we had to have a new furnace before the following winter.
My husband thanked him for being frank and asked him what we should watch for. He gave my husband some suggestions, and said if we had any of those problems, we should call immediately. The noise I was hearing wasn’t part of the list the HVAC technician gave us, so I tried to ignore it. I figured there was some dust blowing around inside the ductwork, and that was why I was hearing some odd scratchy noises. When the noise got louder, and my husband noticed it, he was a bit aggravated. He asked why I hadn’t mentioned it before, and I told him it wasn’t on the list of worrisome things. He shook his head and took a deep breath, to keep from getting angry. I looked at him and asked if he wanted to purchase a new furnace or have a costly repair when we know we need a new furnace in less than six months. He said no, but he wanted to have heat for the next two months of winter. I agreed and said that if the noise got worse or items on the list were happening, then I would call immediately. Two days later, the HVAC technician was knocking on the door. Although my husband agreed with me, he still didn’t like the noise. He called and asked for an appointment when he got to work.
