How Many Watts Does an Air Conditioner Use?

Air conditioners are one of the heaviest users of electricity in your Martinsburg, WV, home. The amount of electricity that an air conditioner uses is measured in watts. It’s important to know this information so that you can make an informed decision about purchasing an energy-efficient system and budgeting for your electricity bill. Read on to learn how many watts different types of air conditioners use and their energy use for different functions.

Central Air Conditioning Watt Usage: Cooling

When your central air conditioning system is running a cooling cycle, it uses about 3,500 watts per hour. This electricity powers the compressor, thermostat, motors, and fans. On a hot and humid day, your air conditioner will run for several hours. To reduce unnecessary cycling, be sure to change the air filter every month.

Central Air Conditioning Watt Usage: Fan Only

The thermostat for your central air conditioning system has a setting called “fan only.” When you switch the cooling system to fan only, it will use about 750 watts per hour. In comparison, a ceiling fan uses about 75 watts per hour. The fan-only setting of your central air conditioner filters and circulates air, but it doesn’t remove heat from your home.

Portable and Window Air Conditioners

Portable air conditioners use 2,900 to 4,100 watts per hour. Their energy use may exceed that of a central air conditioning system because their compressors aren’t as efficient. Small window air conditioners use about 500 watts per hour, whereas medium-size units use 900 watts, and large units use about 1,400 watts per hour.
