While it is true that the fan alone uses less energy than the AC, leaving it on will almost certainly result in higher utility bills. Running the fan constantly also increases your system’s maintenance needs. That’s because the more you run the fan, the faster your filter will get clogged.

Yes, that is your condenser fan motor, it should be running at all times when your compressor is running. You’ll need a multimeter to see if your getting 120 volts to it. If your getting 120 volts to it and its not turning then its bad.

The fan motor in the freezer will not run all the time, it will cycle during a defrost mode and when the unit cycles through the cold control on most models.

Most fans are quite energy efficient, especially in newer systems. The fan itself runs about as much energy as a refrigerator would. This can still add up to $50 a month, or $600 a year. This cost can be even higher if you consider the AC unit working harder to counteract the effects the fan may have.

With a ceiling fan, one can feel about 3 to 4 degree centigrade cooler, therefore if it is used along with an air conditioner, the load on the air conditioner can be reduced by keeping it at a higher temperature.

Fans are cheaper to run than air conditioners, and can be used in place of air conditioners or along with them to save money. You can actually raise the thermostat on your air conditioning unit by 4 degrees without lessening the cooling effect if you turn on the ceiling fan.

The Best Ways to Cool a Room Quickly

1. Switch to CFL or LED Bulbs.
2. Hang Dry Clothes and Handwash Dishes.
3. Limit Hot Meals.
4. Invest in a Misting Fan.
5. Shut Off Computers and Screens More Frequently.
6. Switch to Insulated Curtains or Honeycomb Blinds.
7. Create Natural Convection.
8. Create a Cross Breeze.

AC professionals recommend only using the aircon dry mode for 1-2 hours, at most. While the “Dry Mode” does a good job in lowering air moisture, keep in mind that it shouldn’t be used to completely remove the humidity of the room. It should only be used to maintain humidity at a level that is ideal for human comfort.

Use the “Dry” setting, not “Cool” This mode also runs the compressor at a much lower speed which can cut the running costs of your air-conditioner by up to 50%. This ‘dry’ mode will be most effective in more humid, coastal areas.

If we’re wondering how low it can go, then the general answer is that air conditioners are built to achieve a total drop of around 20F (11C) from the outside temperature. In other words, they’re not made to continually go lower and lower until the room is freezing!
