How To Calculate Air Conditioner Power Consumption. The power draw of a unit that size ranges from 1800 to 2500 watts in most cases. In that post I tried to explain how to calculate AC power consumption by multiplying the max current by the voltage of the AC unit.

It generally costs 013 036 per hour to use a reverse cycle air conditioner to warm a room. Running 3 hours a day is the same as running 9 hours a day for 4 of the warmer months. The temperature is only relevant to the on time.
Multiply that times the voltage and you have the.
Hours Used Per Day. Insulating can also be a helpful step towards reducing air conditioner power consumption if you cant yet replace your air conditioning. If you have a 2 ton unit with a SEER of say 12 then 2 tons X 12000 btuhr ton 24000btuhr 24000 btu hr 12 wattsbtu hr 2000 watts the average power. Enter the tonBTU of AC daily operating hours and cost per unit.
