Fan motors, like other types of motors and light bulbs are stressed the most
on starting up. Run the motor 24/7/360, and it will last a long time. I run
mine continuously and it is now 18 years old.

It will keep you more even and clean your air better , but figure the
cost. I pay 0.12 KWH my fan pulls apx 400 watts or 9600 a day , at
0.12 thats 1.152 a day or 34.56 a month. Well my entire electric bill
last month was 15. I think I like the savings of 350 a year, but you
may enjoy the comfort Also fan motors only last just so long.
