When I was in my 20s I would often house sit for a wealthy couple that lived a few miles away. They just wanted someone to look after the lake house while they were away on holiday. I was grateful to get the work! They had a beautiful lake home and I had it all to myself. I remember one time I was staying there the HVAC system stopped working. It was a pretty hot Summer and I needed the a/c throughout the day to stay cool. I was not sure what to do. After trying to work on the machine myself to no avail, I decided to call the owners. They told me they would promptly call an HVAC company to come out and take a look. The next day a service truck pulled into the driveway and it was a sight for sore eyes. After only about an hour the serviceman said he had found the problem and had repaired it. Sure enough, I felt cool air coming from the air ducts again. I asked him if I owed him anything and he said the owners had already paid him. I hated to have to bother them while they were on holiday but I was certsinly relieved to be comfortable for the rest of my house sitting task.
