A properly functioning central A/C unit should be able to cool a moderate, four-bedroom home by 10 degrees Fahrenheit in three hours. Although the cooling power of your A/C also depends on the power, size, and age of your unit, your home should be noticeable cooler within a few hours.

An average central HVAC unit uses about 3500 watts and runs two to three times an hour for 10-15 minutes. In a 24-hour period, your HVAC would use around 28-63 kWh, resulting in about 850-1,950 kWh in a month, depending on the efficiency of your unit.

Old or Inefficient AC Unit: Older AC units may be less energy-efficient and consume more power. Clogged Air Filters: Dirty filters restrict airflow, making the AC work harder to circulate air. Blocked Vents or Registers: Obstructed vents can reduce airflow, making it harder for the AC to cool your home.
