The service from W F Hann was excellent. John, who worked on repairing the furnace, came immediately, and when his first attempt to fix the furnace did not work, he came back the second day, and replaced the key parts that needed to be fixed; but, on the first day, rather than just trying to replace parts, he worked out what needed to be done (open up more registers), so that when he replaced parts on the second day, it is much more likely that the furnace will keep working. This is excellent! Mark, the plumber, fixed many things in the house, and when I pointed out that when the plunger was down, the new fixture in the sink leaked, he came back the next day and replaced the entire fixture. This is also excellent service, and both service men were courteous, explained what they were doing, and had good advice for keeping things working for the future.
