Central Air-Conditioners use on average 1-kilowatt hour per ton per hour.
A 4-ton air-conditioner will use approximately 4 kWh's per hour.  If a four-ton air-conditioner ran for 12 of the 24 hours in a day the usage would be 48 kWh's per day.  If a customer knows the BTU rating on his air-conditioner you can calculate the tonnage.  12,000 BTU's = 1 ton.
