Mark had always had plans to move to the mountains and live in a cabin. Since he was young, that had been his wish, and his dad took him to a cabin for a short vacation. He loved exploring the woods and the silence, which was so different from the busy city. When the pandemic hit, Mark got an opportunity to own a cabin. His wife was also against the idea since they felt the need to move away from the crowded city life. They bought a cabin in the woods, which came with an oil furnace and so much land with a river cutting in between. The oil furnace was a good model which kept the cabin warm during the many cold evenings in fall and cold days in winter. His wife, at first, was having issues with having an oil tank in the area to supply oil to the furnace. But, an HVAC expert assured them the oil furnace setup was great. However, things weren’t as rosy last week when Mark’s wife discovered a leak from the oil tank. This sent her into a panic as she immediately shut off the oil furnace and phoned Mark, who was in town purchasing supplies. Mark knew an oil leak was a serious issue and requested his wife to ventilate the house even though it was freezing outside. On his way back, Mark passed by the HVAC company and went with an HVAC expert to the cabin to evaluate the oil leak from the oil furnace tank. This was an indoor oil leak caused by a faulty pipe that the HVAC expert replaced to avoid more issues.
