I knew I had a concern with our outdated gas furnace. The gas furnace was almost thirty years old, & I had to get a new 1. I had known the outdated gas furnace was on its last leg for a couple of years. I was looking at unusual gas furnaces, trying to find out which 1 I would prefer. It wasn’t just a choice of oil or gas fuel, even though I also wondered if I wanted to stick with a traditional gas furnace. I considered getting a boiler & getting rid of the ductwork, since there was so much dust that came from ductwork. I was also looking into having a heat pump installed. I had so several questions that I called the Heating, Ventilation, & A/C business & had them send over an Heating, Ventilation, & A/C serviceman. When the Heating, Ventilation, & A/C serviceman arrived, she looked at the gas furnace & the a/c unit. She told myself and others she had a new Heating, Ventilation, & A/C system in the showroom that had a higher efficiency than what I had even when our new was first installed. She showed myself and others a/c units along with gas furnaces. I told him I didn’t want an entire Heating, Ventilation, & A/C system. All I wanted was a new gas furnace. She said every one of us bought the gas furnace & a/c units at the same time. It would save myself and others money to replace both at the same time. Normally, the a/c has a shorter lifespan than the gas furnace. I had no problems with our a/c machine & I couldn’t justify purchasing a new 1. After several thirds of trying to tell him what I wanted & didn’t want, she told myself and others that when I made a choice to call the office; she left.
