Question: how much electricity does a 4 ton air conditioner use?
Answer: A 4-ton air-conditioner will use approximately 4 kWh per hour. If a four-ton air-conditioner ran for 12 of the 24 hours in a day the usage would be 48 kWh per day. If a customer knows the BTU rating on his air-conditioner you can calculate the tonnage. 12,000 BTU = 1 ton.
