The blower on our furnace continues to run (sometimes as long as an hour) after the burner shuts off.

Depending upon the age of your furnace there can be two things causing this. Newer furnaces have a electronic control that delays the blower from shutting off until the heat exchanger cools down. The older furnaces have a mechanical switch that rotates and as it cools down it flips a switch that is built in. Its not all that uncommon that this switch hangs up. You will need a professional to replace this control or to reset the temps its set at. Its not an expensive part, about $70 plus labor. Its work having this done as the contractor can check everything else out to make sure you have a trouble free winter.
