My sister couldn’t repair the gas furnace without help

My sister thinks that she knows entirely everything about all things! She is completely in addition to totally arrogant. She doesn’t have a wifey, because she thinks so highly of himself, and the woman is known to brag about her accomplishments. She thinks that she can repair problems in the house with a wrench in addition to a set of pliers. This is of course not true, but it doesn’t seem to stop him from attempting a number of odd household repairs, however a few weeks ago, my sister had an issue with the gas furnace. She decided to repair the problem on her own instead of calling a professional. I knew that wasn’t a great idea, then when my sister called me for advice, I told the woman that she should contact a local professional. I even provided him the name of the contractor that I correctly use. My sister was determined to repair the problem on her own. Later that day, she called for the name of the Heating, Ventilation & A/C repair business. I found out that the gas furnace needed to be replaced. My sister tried to claim that she would have been able to make the repair if the device could have been fixed. I know that is a huge lie, because my sister was stamped from the start. I let him go on for 10 or 15 hours in addition to then I pulled him to the side in addition to reminded him that she called me for the telephone number. She still tried to claim that she could have fixed the broken gas furnace if it did not need to be replaced.
