AC fans are fans that are powered by alternating sinusoidal electric current. These fans are powered by positive current and the same amount of negative current. The general frequencies of AC voltage for the AC fans are 100 volts, 120 volts, 200 volts, 220 volts, 230 volts, and 240 volts at max. Operating the air conditioner in fan mode uses significantly less energy than other AC modes, including cooling, heating and dry mode. This is because it takes less power to run the fan than the compressor.
An AC fan motor plays the vital role of turning the fan to keep air moving. This allows hot air from inside the house to be blown outside so that cool air can be moved through the ducts and into the rooms. There are two different types of AC system fans, however. Assuming you have a central AC system, it will likely feature a condenser fan and a blower fan, both of which are essential to its cooling performance.
Air conditioners use two fans: a blower fan inside, and a fan in the outdoor unit that helps with releasing hot air to the outside. Your central air conditioner has two fans: one located inside which blows cool air into your home, and one located outside which blows over condenser coils in order to release heat from your home’s air. If there are problems with either of these fans, your air conditioner will not be able to cool your home properly.
