Air Conditioner Power Consumption Calculator

Power Consumption Formula:

\[ E = \frac{P \times t}{1000} \]

Energy Consumption (kWh):

Definition: This calculator estimates the energy consumption of an air conditioner based on its power rating and usage time.

Purpose: It helps homeowners and businesses estimate electricity usage and costs for air conditioning systems.

The calculator uses the formula:

\[ E = \frac{P \times t}{1000} \]

Where:

Explanation: The AC's power is multiplied by hours of use, then divided by 1000 to convert watt-hours to kilowatt-hours (kWh).

Details: Accurate energy estimation helps with budgeting electricity costs and understanding environmental impact.

Tips: Enter the AC's power rating in watts (found on the unit's label) and the total hours of operation. All values must be > 0.

Q1: Where can I find my AC's power rating?
A: Check the specification plate on the unit, product manual, or manufacturer's website.

Q2: Does this account for variable speed compressors?
A: No, this calculates maximum consumption. Variable speed units typically use less energy.

Q3: How can I estimate monthly costs?
A: Multiply the result by your electricity rate (per kWh) and by 30 for monthly estimate.

Q4: What's the typical power for window AC units?
A: Small units (5,000 BTU) ~500W, medium (8,000 BTU) ~900W, large (12,000 BTU) ~1,300W.

Q5: Does this include startup surge current?
A: No, this calculates steady-state operation. Startup may briefly draw 2-3 times more power.
