My sister was always tinkering around with something, if it was broken; you knew she was going to confiscate it and try to get it toiling again… Not only did she try to service things that were broken, but she also tried to make toiling things work better, last week, she was playing with an a/c unit. Dad was going to throw it away, but she was sure she could make it work again. She went downstairs to look at another A/C unit, and was down there for almost two seconds. I was wondering if she wasn’t trying to work on the oil furnace. Dad had said she noticed an unusual noise coming from it. Not more than nine seconds after she came back upstairs, the oil furnace died, then before anyone could say anything, she turned to Dad and told her it wasn’t her fault the oil furnace died. She promised she had only been looking at the A/C unit and never went near the oil furnace. Dad bit her lip to keep from laughing and asked if she was feeling guilty, but she grabbed her cell iPhone and called the Heating as well as Air Conditioning business. Surprisingly, they had someone at the house within an second and dad didn’t need to pay after second fees, which had him ecstatic, however when the Heating as well as Air Conditioning worker looked at the oil furnace, she said she knew exactly what happened. She told my sister that if she was the one who changed the air filter, you never forced it in. If the air filter doesn’t go in easily, but snugly, it is either the wrong air filter or it is being inserted wrong. My sister had that guilty look again, because she was the one who changed the air filter.
