How does the winter setting on a fan work?

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.

Is it expensive to run the furnace fan?

Higher Energy Costs

A standard furnace fan motor uses about 400 watts of electricity every hour. Assuming a national average of 12 cents per kilowatt-hour, let's see how much that would cost you in the long run. If you run your furnace fan twenty-four hours a day, it will cost you a little more than $1.15 every day.

Should I run the fan on my HVAC?

Keeping the fan on creates a more even distribution of heating and cooling, circulating the air if you have cold or hot spots in your house, like a bedroom above a garage. Less frequent starts and stops of the fan can reduce the stress from startup, and potentially help extend it's lifespan.

What does the fan option do on my thermostat?

The 'On' Fan Setting on Your Thermostat

What does the S and W stand for on a fan?

What does the Summer/Winter switch do? This switch is found above the motor on the ceiling fan and sometimes labelled S and W. In the Summer position, the fan will blow cooling air down that you can feel. In the Winter position, the fan will turn in reverse. This blows warm air over the ceiling and down the walls.

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.

How long should my HVAC fan run per hour in winter?

Most systems should run about 2-3 cycles per hour. How long should the furnace or AC run in a given cycle? Typically 10-15 minutes in mild weather. The closer you get to the max design temperature in heating (0 Degrees) or cooling (90 Degrees) the longer the run cycle will be.
