When the HVAC tech came in and did the inspection on our furnace, he also inspected the ductwork.
He told us he had noticed a couple of cracks along the seams of the ductwork.
He wanted to call a team of professional ductwork cleaners and have them inspect the entire ductwork system and see if it needed repaired or replaced? If it was able to be repaired, they would repair the ductwork, then clean and sanitize it. I worried about what it was going to cost if I needed to replace the ductwork. I knew it had to be pretty old. The ductwork was already in the house when we bought it, nearly fifteen years earlier. I agreed to have the ductwork professionals come to the house and inspect the ductwork. When they arrived, I asked them why the ductwork was so important. They explained that the ductwork was like a major highway. It is how the heating and air conditioning is directed through the entire house. When there was a crack or hole somewhere in the ductwork, there was a loss of heat or AC coming through that hole. We would be wasting energy since we didn’t have proper airflow, and there was a loss of energy/HVAC. I didn’t want to be losing heat or air conditioning, but I knew it would be expensive to replace the ductwork. I held my breath as the inspection was done. Luckily, all they had to do was seal the ductwork, and then they cleaned and sanitized it. Our ductwork was good for at least another two years.
