Just looking for some opinions. I got a call a few weeks ago from some former neighbors with whom I was friendly with. They said that the unit seemed to be having a hard time cooling, offered to come over and take a look, left this as a message and never heard back. Fast forward 1 week and I hear from them again. This time they say that the unit was "struck by lightning" and their insurance co. asked them to get a estimate on repairs. So I go over and find a t-stat and zone control bad. I happen to have an extra zone control of the exact same model. I wire the unit to run temporarily from the upstairs stat, do a quick check of the system(it is 8:30pm after a long day and I have not been home yet), and explain what I found. To my surprise they seem less than happy. I get the impression that they wanted my to condemn the entire system so that they can make a large insurance claim and include some other electronics that may or mayor may not have been damaged by this "lightning". Then the next day I receive a message saying the outdoor unit does not seem to be working. I am considering just going back and putting the system back to the condition I found it and telling them to contact someone else...frustrated and feeling like they are trying a abuse our friendship. What are the opinions here on doing work for friends, family, and neighbors??
