For afternoons, our fiance had been complaining about the noise in the walls. He was sure there was something wrong with the HVAC duct or the gas furnace. He said the noise sounded akin to something inside the HVAC duct, and it had to be the heating being forced through so hastily. I listened to the gas furnace, however nothing sounded off. It was turning on and off at official intervals. The heat was just as fantastic as it was the day we got the gas furnace. I remembered those sounds from when I lived with our parents. I told him I didn’t think the noise had anything to do with the heating, ventilation and A/C system. I thought the noise was coming from an invasion of mice in the house. He thought this was nonsense and he wanted to call the heating, ventilation and A/C business. I made a bet with him. If he called the heating, ventilation and A/C company and they told him it was just mice in the walls, he would pay for the exterminator, and take me away for a weekend. He was so sure he was right about the heating, ventilation and A/C system, that he took our bet and shook hands with me. When the heating, ventilation and A/C serviceman arrived, he looked at the gas furnace and then he looked inside the HVAC duct. He turned to our fiance and told us he thought we had mice in the walls, because the heating, ventilation and A/C idea was fine. I patted our fiance’s cheek and told him I would look to see where I wanted to go for the weekend. He could call the exterminator and have the mice eliminated before we got home.
