Calculate AC units
Reviewed 10 July 2026. AC wattage is a planning estimate. Actual units vary by room size, thermostat, compressor load, insulation, maintenance, and outdoor temperature.

Quick AC Bill Answer

A 1.5 ton inverter AC used for 8 hours daily can consume about 312 units per month. At Rs 55 per unit, that is roughly Rs 17,160 before taxes, FCA, QTA, fixed charges, and arrears. A non-inverter 1.5 ton AC used the same way can consume about 432 units/month, or roughly Rs 23,760.

Solar impact2.6kW

The solar impact number means this AC usage alone may require roughly 2.6kW of solar generation capacity under Bijli Hisab's Pakistan-average monthly generation assumption.

AC Unit Counter Formula

The simple formula is: watts x quantity x hours per day x days per month divided by 1000. For example, one 1.5 ton inverter AC using 1300 watts for 8 hours a day over 30 days is about 312 units per month.

1.5 Ton AC Bill Per Month in Pakistan

A 1.5 ton AC is one of the most common household loads in Pakistan. At Rs 55 per unit, an inverter 1.5 ton AC used for 8 hours daily can add roughly Rs 17,160 per month before taxes and adjustments. A non-inverter 1.5 ton AC can add more because its average running load is usually higher.

For a dedicated 1.5 ton AC cost breakdown with 4, 6, 8, 10, and 12-hour scenarios, see the 1.5 ton AC bill per month guide.

Inverter AC vs Non-Inverter AC Bill

Inverter ACs usually have a lower average running load when the room is cooled and the compressor slows down. Non-inverter ACs usually cycle at a higher fixed load, so the monthly units can be higher for the same hours. The difference becomes more visible in long summer usage, especially at 8 to 10 hours per day.

1.5 ton inverter estimate: about 1.3 units/hour.
1.5 ton non-inverter estimate: about 1.8 units/hour.
At 8 hours daily, the difference is about 120 units/month.
Actual savings depend on thermostat, room heat, and AC condition.

How To Reduce AC Bill

Use realistic temperature settings instead of overcooling.
Clean filters and service the outdoor unit before summer peak.
Improve curtains, sealing, and room insulation where possible.
Estimate total household units before buying solar only for AC.
