We had the HVAC service technician at the house last week.
Mom was sure there was a problem with the furnace, but I didn’t hear anything. Every morning, she would wake up and complain about the noises she heard all night. She said there were groans coming from the ductwork, and it sounded like something running up and down the ductwork. I laughed at her description and said that maybe there were goblins stuck in the ductwork and they were trying to get. It was Halloween! She slapped my head and told me to get ready for school or I would miss the bus. I came home that afternoon, and the HVAC technician was at the house. She must have really believed there was something in the ductwork if she called the HVAC company. The HVAC technician was looking into the air vents and trying to see if he could see something. He had already said the groan was the pipes expanding when the heat blew through the ductwork. It was a normal sound and once she got used to it, she wouldn’t notice the sound. The running had him baffled. He said he put a stethoscope up to the ductwork, but he heard nothing. An hour later, I heard the noise. I told mom I thought we may need an exterminator because it sounded like there were mice in the ductwork. She called the HVAC company and told them what I said. She said he was the HVAC service technician, and she needed cleaning and eviction service for the ductwork.
