Hoping someone can validate what I was told about running a furnace fan blower. I have a 2 story house that typically stays cold in the basement, okay on the main level, and warm on the second level when the a/c is running. I was told to put the fan blower to "ON" instead of "AUTO" and just let it run all the time. I've done this for two days and the results are amazing. The basement is warmer, main floor still okay, and the upstairs cooler. The question/concern I have is if this could prematurely burn out the fan motor or cause any other problems by running it all the time. Appreciate any input/advice on this....thanks.
