In the winter, ceiling fans on the winter mode will rotate clockwise. The mode is usually used at a low speed in order to pull cool air up. The clockwise rotation pushes the warm air that has naturally risen back down. Through this, you keep the hot air down instead of losing it up near the ceiling.

Should I run the fan on my HVAC?

Does reversing fan make warmer?

By switching the direction that your fan blades turn, that cooler air is drawn upwards, which forces the warmer air near the ceiling back down into the space.

What fan speed should I use for heating?

To calculate your needed fan airflow for the heating mode of operation, divide the furnace's rated input by 10,000. This will give you the necessary multiplier to obtain the cfm per 10,000 Btu for the gas furnace type you're setting up. Let's say you have a 60,000-Btu input, 90 percent-plus furnace.
