cost to run home air conditioning
For an average 3 ton (36K BTU size) 17 SEER (efficiency rating) we would expect total power draw to be 1.89 KW per hour, with summer cooling hours of 1,100*, and a cost of $0.06 per KW. 1.89 x .06 x 1100 = $124.00 per year for an average (will increase if thermostat is set lower) or $0.1134 cents per hour.
