Had an emergency call for a no cool. Woman said her son was deathly ill and bed bound. Had to have the ac fixed asap. Whet to the home, pulled the plugged filter and let the evap thaw. Cleaned the plugged evap. Checked operation, cond was screaming. Condenser coil was also plugged and had to wash it out several times to get it cleaned. Unit was running well so I presented the bill. She fussed about the bill. Told her at least her son would be comfortable. She then told me that it won't have any affect on her son because he was in the hospital. Had to bite my tongue, it was sore for a week.
