How Much Does It Cost to Run an Air Conditioner in Karachi, Pakistan?

The cost of operating an air conditioner in Karachi, Pakistan, can vary based on several factors, including the type and efficiency of the unit, electricity rates, and usage patterns. This article provides a comprehensive breakdown to help you estimate these costs.

Electricity Rates

As of 2023, the average electricity tariff in Karachi is approximately PKR 30 to PKR 40 per kWh, depending on the provider and the consumer's usage slab.

Air Conditioner Power Consumption

A typical split air conditioner consumes between 1.0 kW to 2.0 kW per hour. For example, a 1.5-ton AC generally consumes about 1.5 kW.

Usage Patterns

If you run the air conditioner for 8 hours a day, the calculations would be as follows:

Cost Calculation

Daily Cost:

For a 1.5 kW AC running 8 hours:

Energy used 1.5 kW × 8 hours 12 kWh

Cost 12 kWh × 35 PKR/kWh 420 PKR

Monthly Cost:

Monthly Cost 420 PKR/day × 30 days 12,600 PKR

Factors Affecting Costs

AC Efficiency: Inverter ACs are more energy-efficient than non-inverter models, which can reduce costs.

Ambient Temperature: Higher outdoor temperatures may lead to longer running times, increasing costs.

Insulation: Better-insulated rooms require less cooling, thus reducing costs.

In summary, running a 1.5-ton air conditioner in Karachi for 8 hours a day could cost around PKR 12,600 per month, depending on the electricity rate and the efficiency of the unit. Adjustments can be made based on actual usage and the specific characteristics of the air conditioner.

Additional Considerations

The cost of running an AC also depends on the AC's power rating and usage duration. On average, it can cost PKR 20-50 per hour. Keep in mind that this is a general range, and actual costs may vary.

For new 1.5-ton inverter ACs, if they are run for almost 15-16 hours a day at a constant temperature set at 24°C, the monthly cost should not exceed PKR 5,000. This amount is exclusive of other appliances that may be used concurrently.
