About twice a year, turn off your furnace and A/C, pulling your furnace door(s) off, taking out the filters, take your vaccuum cleaner and clean around your furnace fan and motor. Use a flashlight & look for any oil caps, that might need a drop or 2 of 3 in 1 oil. Cleaning the motor and fan will make the fan motor run cooler.
