Electricity Usage & Cost of a Air Conditioner (Central)

A central air conditioner is a powerful system designed to cool your entire home, providing comfort during the hot summer months. On average, a central AC unit uses around 3500 watts while operating, but the energy usage can range between 2000 to 5000 watts depending on the size, efficiency, and age of the unit, as well as the home's insulation and climate. Central AC systems are composed of an outdoor unit and an indoor unit that work together to circulate cool air through ducts to every room in the house.

Several factors influence the energy usage of a central AC:

  1. Size and Capacity: Larger homes require more powerful units, which consume more energy.
  2. Efficiency Rating: Units with higher SEER (Seasonal Energy Efficiency Ratio) ratings use less energy.
  3. Thermostat Settings: Lower temperature settings increase energy consumption.
  4. Maintenance: Regular maintenance, such as cleaning filters and servicing the unit, can improve efficiency and reduce energy usage.
