How the estimate is calculated
We use typical average power for each size while the aircon is running: about 1.1 kW for a 1 ton non-inverter unit, scaled for other sizes. Inverter units are assumed to average about 45% less once the room reaches the set temperature.
Monthly cost = power (kW) × hours per day × days × rate per kWh × number of units.
Real consumption depends on the room, the set temperature, insulation, outdoor heat and how clean the unit is. Setting 24–25°C instead of 18–20°C and keeping filters clean are the cheapest ways to save.
Questions
How much electricity does a 1 ton aircon use?
A 1-ton non-inverter unit draws around 1.0–1.3 kW while the compressor runs. An inverter unit of the same size usually averages much less once the room is cool.
What electricity rate should I use?
Use the total rate per kWh from your latest DEWA, ADDC or SEWA bill (slab tariff, fuel surcharge and 5% VAT), typically about AED 0.30 per kWh in Dubai. It differs by emirate and consumption slab.
Does cleaning the aircon reduce the bill?
Yes. Dirty filters and coils make the compressor work longer to reach the set temperature.
