DEAR BARRY: When I bought my house, the home inspector found nothing wrong with the furnace, but his report says, "The furnace may need maintenance or repair soon." This did not seem urgent at the time, so we bought the house, assuming that the furnace was operative. But yesterday, the man from the gas company said the furnace has code violations and is not safe to use. I don't understand how my home inspector missed these problems. What should I do? --Heather
DEAR HEATHER: It would help to know exactly what kinds of code violations are involved. Not all code violations are difficult or expensive to repair. Specifics matter a lot.
