They would be storing nuts in the ductwork if they could but he said the HVAC company would take all that crap out when they did the ductwork cleaning.
I was quite surprised when I started hearing something running around in the ductwork. It was the fall season and I was already thinking about getting my heating system maintained. I didn’t want to have a bunch of dead critters in my ductwork so I called the HVAC company and told them about what was going on. They advised that I reach out to a pest control company first before having my ductwork system cleaned. They said there had to be someplace where the pests were getting into the ductwork and that would have to be sealed. They also said with an opening to the ductwork, that meant there was leakage that would be making my energy bills go up whenever I used the HVAC system. I thought the energy bills were a little costly towards the end of the summer season. So I had a pest control person come out and he learned it was squirrels that were prancing around in the ductwork. He said they were probably setting themselves up for winter with food storage and all. They would be storing nuts in the ductwork if they could but he said the HVAC company would take all that crap out when they did the ductwork cleaning. He had me turn on the system fan as he sprayed a sleeping agent into the ductwork that would knock the squirrels out. Then he would be able to pull them out of the ductwork system with his vacuum tool. He said it was a fairly gentle tool that wouldn’t hurt the squirrels and they would be released back into the wild. I was just happy when the squirrels were gone, but now I need the HVAC pros to take care of the rest.
