A small extra or goodwill is helping move a couch. Anything electrical is $$. As soon as they ask you need to tell them the price to do it. If someone is asking you to do the work they are willing to pay a price. If not do you really want there business. Anyone they refer you to is going to try the same thing. I shy away from conflict but being paid for my time shouldn't create tension. They aren't about to come over to your house and work for free are they?
