I’m not used to being alone anymore. Ever since my child went overseas, my hubby and I have been taking care of our ten-year-old grandson. She is a fascinating young lady She wants to suppose everything she can learn about everything. My hubby is an Heating, Ventilation, and A/C worker. She works some long hours and our grandson adores him. She even asked if she could go along on her service calls so she could learn more about air conditioners and furnaces. My hubby was glowing; She was so enthusiastic to have this young lady want to tag along with him. When she was called to a condo because the furnace wasn’t working, she took Mason with him. The furnace ultimately had to be updated. The owners hadn’t changed the air filters, which caused a lack of airflow. The airflow had been blocked off for quite some time because it had caused irreparable mangle to the furnace. My hubby told them they were lucky to have called for Heating, Ventilation, and A/C service when they did. They could have ended up with carbon monoxide leaking into the house, which could be deadly. Later that week, my hubby was working her proper shift with the Heating, Ventilation, and A/C dealer. My grandson disappeared for a couple hours. At first I thought nothing about it until I heard him coming from the basement. She told myself and others she had changed the air filters in the furnace and the a/c unit. She wanted nothing happening to myself and others if the air filters were neglected and carbon monoxide leaked into the air. I don’t suppose what I did before I had him around all the time.
