Question:

I have a two-story house with a basement, built in 1952. Is it a good idea to turn the furnace fan on, to distribute the heat throughout the house?

Answer:

H014 - Warm Air Furnace Fan and MotorYes and no. If you have a problem with a cool area when heating or a warm area when running the air conditioning, operating the fan continuously will even out the temperatures in your home. The downside is this will cost electrical energy to run the fan and cause some wear and tear on the fan. However, you can run a fan on a newer, high efficiency forced air furnace with an ECM or variable speed motor for little cost – about 1/10 the cost of a typical fan motor. Finally, I think your first step is to have a contractor inspect and adjust your system. At times, duct dampers can be adjusted to correct cold spots and air flow problems. Often you need to make a spring and fall damper adjustment for a two story home.
